@Socoolscienceshow No, not really... you got me, I don't know anyone except the chinese guy who juggles the knives at the local Chinese buffett and Sarah Palin. But I was wondering if someone else did it. :)
Well actually, diesels dont work the same way your experiment did. Diesels work off of pure compression, which is why they take so long to start \ dont fire right off ( ESPECIALLY in colder weather.) the piston goes down, allowing air in, the intake valve shuts, and the injector shoots fuel in. as the piston comes back up it compresses this air \ diesel mixture so much it explodes. Then the piston shoots back down super fast, shooting the opposing linked piston up super fast. :]
@NickelbackPWNS Wrong! The piston when goes up it only compress the air (not air \ diesel mixture) when its near the Top Dead Center-TDC the injector injects the diesel and because the air is so hot it burns the diesel (combustion) pushing the piston down again. Diesel does not explodes it burns, explosion is in petrol engines!
@hellhunter359 Im not sure if your saying add damn science to the phrase "and that is why damn science" see that jus doesnt sound right, "and that is why science... is so cool.
and if your say its just damn science meaning who cares well if you enjoy this engine or mroe importantly enjoy your computer well its not just DAMN science its DAMN cool science.
diesel engine goes about 20+ : 1 compression ratio. increase in comprsion increase the heat. therefore, there is no spark plug needed in diesel engine.
Umm petrol produces more power in an otto-cycle engine because: petrol is burnt more easily and quickly and also requires less air then diesels. Additionally, the high compression ratios in diesel engines means that they have to operate at low RPMs (also because the fuel needs more time to burn due to longer chains), so according to the equation HP = TQ x RPM / 5252, petrol engines generally produce more power.
@PetrolDemon I hate to break it to ya bud, but your wrong.A diesel burning the same amount of fuel as a gasoline engine at say 1600 RPM, will produce much more power. The big loophole in you statement there is the equation, while the torque of the diesel is around 1 thousand pounds, the gasoline will be a wimpy 3-400 pounds. Therefore the diesel produces more power. Don't believe me? Go to every ship, semi, and farm tractor you can find and see what it burns.
@UncleBubbles94 I understand what you mean, but I'm saying that top end power is greater (usually) in a comparable petrol engine (talking small displacements), will produce more power at the upper end as the torque may be lower, but RPM can reach say 9,000 whereas a diesel engine will be only able to rev to areound 4-5,000, so although the torque is significantly greater, the rpm is also much lower. But yes, at say 2,000 rpm a diesel will produce more power than a petrol at 2,000.
@UncleBubbles94 I understand what you mean, but I'm saying that top end power is greater (usually) in a comparable petrol engine (talking small displacements), will produce more power at the upper end as the torque may be lower, but RPM can reach say 9,000 whereas a diesel engine will be only able to rev to areound 4-5,000, so although the torque is significantly greater, the rpm is also much lower. But yes, at say 2,000 rpm a diesel will produce more power than a petrol at 2,000.
@PetrolDemon yeah engines do but its bad if they use less air in them cus the stocheimetric ratio for petrols are 14.7:1 which means if they burn twice as much fuel if a 2.2litre petrol than a 2.2 litre diesel than the effeicency rating on that will be lower since burnt fuels release carbon, hydrogen ect which are green house gases and there fore the petrol releases it quicker.
@truemagicskillz1 you also need to understand that a diesel cannot obtain a true stoikiometric ratio, with a diesel engine, it ingest's more air then what it needs to the amount of fuel it requires.
@mxtj3wboi they dont bother me at all people get jelouse of people who do better then they do on youtube here, its all part of the job. Besides there are plenty of people who enjoy these sci files and I think I ow it to at least those people to keep making new sci files :D

@InfernoEdge outback zach is way more annoying then me, all he does is yell about stupid things too I men the guy is a low class loud mouth that wouldnt even fit in anywhere near my level of personoa.
@prepaidbrian There is no such thing as a low compression diesel. Glow plugs are just another way to warm up the air inside the combustion chamber. Intake heaters essentially do the same thing, but they heat up the air before it goes into the engine, whereas glow plugs heat it up when it's already in the engine.
@UncleBubbles94 Actually cars that use diesel such as Mercedes and Volkswagen are considered low compression diesels, and some trucks are low compression, a low compression diesel is 17-20.1 anything higher than 20.1 is a high compression diesel, and glow plugs are not in the combustion chamber they are on the fuel injector using a pre ignition then being forced into the combustion chamber. Try Again...
@prepaidbrian I have already explained and not going to waste my time on that anymore. But let me explain how much of a moron you are if you can't understand a simple fact. You need to put yourself into one piece and get some education, you can do shit as long as you are in front of the keyboard but if I see you across the street things will be very different for you smallchild.
@Dosalt Maybe u need the education seeing as how I am enrolled in college to be a mechanic? If you dont believe I will give you the name of my school, Ivy Tech, East Chicago Campus, I am being trained by ASE not on youtube, hence why I have proved 3 people wrong already. small child, I am more or less older and bigger than you..good bye
@prepaidbrian My, my, you think that enrolling in a school makes you superior to everyone else here? You fucking retard, it's people like you that are the reason everyone has to get that useless and exorbitantly expensive 'piece of paper' just to be able to make a living now. What ever happened to common sense.
@racefactory900 No you fucking idiot, it doesnt make me superior but showing I am in school as a mechanic and learning diesel as well...if some of you would get the same piece of paper you would make a better living for yourself, and common sense is not available when it comes to machinery now who's the fucking retard hmmmm
@prepaidbrian Its mainly used for cold temperatures where the diesel fuel cannot compress and generate the heat needed to combust . The glow plug will aid in heating up the fuel/air mixture and combusting the fuel
Diesel engine is NOT necessarily powerful than gasoline engine, it's a meaningless comment. A gasoline engine can be made to produce the same power as that of a semi. Diesel has more Carbon compared to gasoline, and by burning more carbon you get more energy, that's all it is. To make the same amount of energy you need more gasoline compared to diesel.
@Dosalt Wrong, you don't need more gasoline, you need a fuel with higher octane or pure alcohol, normal road vehicles would not have 17-25.1 Compression those would be considered drag cars. and higher compression means more torque not horsepower.
@jblsound13 well they burn up fule more efficently then the diesel engines do, how-ever they are currently working on ways to create bio-fules that would work in a deisel engine which would be efficent and renewable :)
@Socoolscienceshow actually a gas engine is its most fuel effecient within its first 1000 miles a diesel is its most fuel effecient at 150,000 miles, diesels are also better for the enviorment the black smoke isnt oil its unburnt fuel the smoke however is to heavy and cant reach the ozone layer there for gas engines are less enviormentally friendly than a diesel, today however if a brand new truck smokes its broke new EPA systems have removed the black smoke effect....
@Socoolscienceshow with exhaust systems and the adding of a chemical called urea they are able to greatly reduce a pollution problem all engines gas and diesel create called oxides of nitrogen not NOx, so if you take a prius and a well maintained diesel side by side the prius actually pollutes more than the diesel, and are able to produce mpg numbers in the 25+ and able to tow a small house! if you have further questions that need true answers send me a message :)
Diesel engines arent more powerful. Simply are more torquier. More G's per combustion, considering the pressure rate which is a lot higher. Yet less revvy and linear than petrol ones...
I appreciate your attempt to make educational videos, in fact I support it, though I wish you would take the time to be a little more detailed as this video misses key pieces to the function of that engine. While it used compression for the ignition its vital that the fuel [diesel] be atomized via injector [10,000 PPM upto 50,000 ppm] which allows for a far easier time causing the ignition due to the higher flash point of diesel. There's obviously more details but those take time to learn
@phantomkitsunezero The series socoolscienceshow is not ment to be a a full fledge colledge course where you gain all the information you could possibly learn but rather a spark to get people more interested in a topic enough to make them want to learn more about that subject. I really wish I had the time and money to put more information into these videos, how-ever the current time it takes me to put one of these videos together is already more time then I want to extend into these 3-4min films
i dont know why i clicked on this video...I clearly know more on how this type of engine works...just like a jet engine. You need some serious compression in order to make the explosion happen. If you just tried to ignite diesel on its own the flame will go out almost as fast as it started since diesel fuel is not already oxidized. Normal gasoline is oxidized so you can lite it under just about any compression. Only reason why those trucks use diesel is due to the amount of torque they produce.
@fightingfalconfan where are you people coming from??? The point of the demonstraion is not to say that deisel engines ignight by just using pressure, but rather to show people that heat can ignite a fule souce such as that craeted when the fuel source in a deisel engine is heated through compressure to create an explosion. You know what the problem is... to many of you rednecks are clicking on this vidoe and I dont really like you redneck people very much.
@Socoolscienceshow Not a redneck here. Far from it in fact. I just know the differences between regular gas engines and diesel engines. from what i could tell of that spray thing you did it wasn't gas like in the engine your trying to show. Diesel works on almost purely compression alone. Were regular gas needs the spark to do the same thing. Its just how diesel is created and refined is the key. If you take a look at both engines, you will notice the diesel one is bigger..
@Brodes1983 cuz trolls are destroying a good video becuz they are jelous that they are not getting the same amount of views and attention as I am, thus they think they can destroy a good video by rating it down. Dont worry Im going to youtube partner meet up soon where I will be making a case to remove the voting bar so good videos like this one dont get destroied out of jelousy.
@Socoolscienceshow I say good on ya, keep it up. At least you are the one doing these vids for people to watch, at least you have the time, effort & balls. Good stuff.
@bigdantootcorps you shut off the fuel injector by turing the ignition off, with out fuel being injected there wont be any more controled explosoins and the engine will stop working.
@Socoolscienceshow Nope, i looked it up and "when something is activated , it is made active; when something is actuated , it is moved to take action (or produce a consequence)
to actuate is a general word meaning 'to set working' and has more to do with mechanical action - while activate is used mainly in scientific expressions " sas the consequence is a squirt of diesel.
You made me uncertian since english isn´t my native tounge, but i know my diesels.
@Socoolscienceshow mechanically 'actuated' is correct, and you don't turn off the ignition to a diesel. Old diesel engines had a handle you pulled out which cut the fuel supply. New diesel engines have an electric solenoid which cuts the fuel supply. There is no ignition system to be turned off. They are ignited by compression, never heard of compressure.
very informative ........i actually enjoy the annoying bill nye the science guy approach ......my only gripe is the political comment .......really...........inform us don't direct us..... outstanding video.
@nothinglikesleeping diesel is made from left over crud from making petrol, the original diesel engines ran vegetable oil, but the oil company's found they could run on there waste so they pushed that out to make more money... funny that :)
You forgot the part when fuel is actually injected in the piston. And diesel engines are not more powerful than gasoline. Diesel engine is just more fuel efficient (because compression ratio is higher)
@nejckra you do the video experiment, have a gas engine pull a truck trailor and when I see a tiny lil gas engine pull the wight of a massive truck trailor for the same distances with out blowing out over the same life span, I will accept that.
@Socoolscienceshow Actually "tiny lil gas engines" are not made for truck trailor towing. Have you really just gave me a challenge to pull a truck trailor with 2 litre gasoline engine, when a truck engine has at least 10 litres (diesel or gasoline)? If you want to compare engines you take two engines (one gasoline and one diesel) of the same size. Note: ALL modern diesel engines have turbochargers
/watch?v=3eG_sD8yD40
Sincerely, Your student of mechanical engineering.
@Socoolscienceshow Diesel combustion engines are designed to take intense heat and pressure for very long periods of time, hence they are built a whole lot better. That's why their lifespans are much longer than that of gasoline combustion engines. You can have a gasoline engine still pull a trailer but the engine is more suspected to wear and tear faster than that of a diesel since the engine is not as heavy built. Build it (the gas engine) heavier and you will have a challenge.
@nejckra no diesel engines have more more energy than gasoline engines, they last longer with less maintenance they can be abused more because there parts are more durable, yes diesel are more fuel efficient but there more fuel efficient because of the way the fuel is ignited and how much less of it is used than a gasoline engine. gasoline engines in trucks 200'000mi. to 300,000mi. if you treat them right. diesel engines 500,000mi. to 800,000mi. or MORE. Diesels have more energy per gallon.
You forgot something! On modern diesel cars the glowplug is used for another purpose on (manual transmission). The clutch has a switch under it, so when you press it, the glowplug heats up and burns off excess diesel. It's to prevent smoke. If you see a smoking diesel it means too much fuel is going in to the cylinders. Caused by crap diesel tuning boxes. The excess burns off in the manifold, EGR, CAT, DPF and also fouls the exhaust valves - they stick open and reduce power & kill the engine
@urbex2007 thats true but I cant put everything into a 3-4min video. I would do it but that would drag the vidoe out into like 5-8mins long. I like to keep the sci files short because if I go too long they tend to not be watched all the way through and whne youtube looks at my videos thats makes me look bad when people dont watch all the way through. So to keep youtube happy and to keep the sci files interesting I keep them short.
@urbex2007 glow plugs are only used when its cold glow plugs dont burn off excessive fuel and diesel will smoke anyway the really cold more than anytime i never heard of a tuning box more like a injection pump if excess fuel burns off in the manifold and fouls up exhaust valves and make them stick open then repair shops would be rich on fixing this problem iem not saying you dont know what your talking about i am just saying your just slightley off on the info (no insult intended)
@Socoolscienceshow a diesel engine compresses the gas into a tiny space even tinier than a gasoline engine and makes it explode by moving the molecules of the gas around so fast that it ignites and thats what they call the power stroke
@chevytrucker1 I don't know the answer to that question. But you can travel more miles with a gallon of diesel than with a gallon of petrol. In the UK, even though diesel is more expensive, it proves more economical in the long run as you can do more miles with the same quantity of fuel.
@JackMacyntire Trucking companies use diesel trucks primarily because they have more torque at lower rpm than a petrol engine would have. The more torque you have the more towing capabilities you have. You're thinking of horsepower when thinking of diesels as not being "powerful". But you are definitely correct that they are much more efficient engines!
@Socoolscienceshow i think thats not a fair comparison... try pulling a load that bodybuilders pull with their big muscles with your tiny little arms. it wont even move... :S not saying youre wrong though... not an expert in engines

Diesel engines...
1. Run on Diesel fuel
2. Are compression ignited (compressed air creates the heat needed to ignite)
3. Composed of heavier and stronger parts
4. Sometimes use glow plugs to pre-heat the air.
5. Are Direct Injected into the combustion chamber. Gasoline, the intake manifold)
6. Are more efficient (and durable)

Diesel engines arent more powerful. Simply are more torquier. More G's per combustion, considering the pressure rate which is a lot higher. Yet less revvy and linear than petrol ones...

I appreciate your attempt to make educational videos, in fact I support it, though I wish you would take the time to be a little more detailed as this video misses key pieces to the function of that engine. While it used compression for the ignition its vital that the fuel [diesel] be atomized via injector [10,000 PPM upto 50,000 ppm] which allows for a far easier time causing the ignition due to the higher flash point of diesel. There's obviously more details but those take time to learn

@phantomkitsunezero The series socoolscienceshow is not ment to be a a full fledge colledge course where you gain all the information you could possibly learn but rather a spark to get people more interested in a topic enough to make them want to learn more about that subject. I really wish I had the time and money to put more information into these videos, how-ever the current time it takes me to put one of these videos together is already more time then I want to extend into these 3-4min films

i dont know why i clicked on this video...I clearly know more on how this type of engine works...just like a jet engine. You need some serious compression in order to make the explosion happen. If you just tried to ignite diesel on its own the flame will go out almost as fast as it started since diesel fuel is not already oxidized. Normal gasoline is oxidized so you can lite it under just about any compression. Only reason why those trucks use diesel is due to the amount of torque they produce.

@fightingfalconfan where are you people coming from??? The point of the demonstraion is not to say that deisel engines ignight by just using pressure, but rather to show people that heat can ignite a fule souce such as that craeted when the fuel source in a deisel engine is heated through compressure to create an explosion. You know what the problem is... to many of you rednecks are clicking on this vidoe and I dont really like you redneck people very much.
Socoolscienceshow 1 month ago
@Socoolscienceshow Not a redneck here. Far from it in fact. I just know the differences between regular gas engines and diesel engines. from what i could tell of that spray thing you did it wasn't gas like in the engine your trying to show. Diesel works on almost purely compression alone. Were regular gas needs the spark to do the same thing. Its just how diesel is created and refined is the key. If you take a look at both engines, you will notice the diesel one is bigger..
fightingfalconfan 1 month ago
@Socoolscienceshow and the regular gas one is much smaller. Diesel is a bigger bang.

@bigdantootcorps you shut off the fuel injector by turing the ignition off, with out fuel being injected there wont be any more controled explosoins and the engine will stop working.
Socoolscienceshow 2 months ago
@Socoolscienceshow nah, its more like shut the fuel off, the injector is mechanically actuated.
smirnofowner 2 months ago
@smirnofowner you mean "mechanically activated"???
Socoolscienceshow 2 months ago
@Socoolscienceshow Nope, i looked it up and "when something is activated , it is made active; when something is actuated , it is moved to take action (or produce a consequence)
to actuate is a general word meaning 'to set working' and has more to do with mechanical action - while activate is used mainly in scientific expressions " sas the consequence is a squirt of diesel.
You made me uncertian since english isn´t my native tounge, but i know my diesels.

smirnofowner 2 months ago
@Socoolscienceshow mechanically 'actuated' is correct, and you don't turn off the ignition to a diesel. Old diesel engines had a handle you pulled out which cut the fuel supply. New diesel engines have an electric solenoid which cuts the fuel supply. There is no ignition system to be turned off. They are ignited by compression, never heard of compressure.

You forgot the part when fuel is actually injected in the piston. And diesel engines are not more powerful than gasoline. Diesel engine is just more fuel efficient (because compression ratio is higher)

@nejckra you do the video experiment, have a gas engine pull a truck trailor and when I see a tiny lil gas engine pull the wight of a massive truck trailor for the same distances with out blowing out over the same life span, I will accept that.
Socoolscienceshow 2 months ago
@Socoolscienceshow Actually "tiny lil gas engines" are not made for truck trailor towing. Have you really just gave me a challenge to pull a truck trailor with 2 litre gasoline engine, when a truck engine has at least 10 litres (diesel or gasoline)? If you want to compare engines you take two engines (one gasoline and one diesel) of the same size. Note: ALL modern diesel engines have turbochargers

nejckra 2 months ago
@Socoolscienceshow Diesel combustion engines are designed to take intense heat and pressure for very long periods of time, hence they are built a whole lot better. That's why their lifespans are much longer than that of gasoline combustion engines. You can have a gasoline engine still pull a trailer but the engine is more suspected to wear and tear faster than that of a diesel since the engine is not as heavy built. Build it (the gas engine) heavier and you will have a challenge.

Lowend65 2 months ago
@nejckra no diesel engines have more more energy than gasoline engines, they last longer with less maintenance they can be abused more because there parts are more durable, yes diesel are more fuel efficient but there more fuel efficient because of the way the fuel is ignited and how much less of it is used than a gasoline engine. gasoline engines in trucks 200'000mi. to 300,000mi. if you treat them right. diesel engines 500,000mi. to 800,000mi. or MORE. Diesels have more energy per gallon.

Socoolscienceshow 2 months ago
You forgot something! On modern diesel cars the glowplug is used for another purpose on (manual transmission). The clutch has a switch under it, so when you press it, the glowplug heats up and burns off excess diesel. It's to prevent smoke. If you see a smoking diesel it means too much fuel is going in to the cylinders. Caused by crap diesel tuning boxes. The excess burns off in the manifold, EGR, CAT, DPF and also fouls the exhaust valves - they stick open and reduce power & kill the engine
urbex2007 3 months ago
@urbex2007 thats true but I cant put everything into a 3-4min video. I would do it but that would drag the vidoe out into like 5-8mins long. I like to keep the sci files short because if I go too long they tend to not be watched all the way through and whne youtube looks at my videos thats makes me look bad when people dont watch all the way through. So to keep youtube happy and to keep the sci files interesting I keep them short.
Socoolscienceshow 3 months ago
@urbex2007 glow plugs are only used when its cold glow plugs dont burn off excessive fuel and diesel will smoke anyway the really cold more than anytime i never heard of a tuning box more like a injection pump if excess fuel burns off in the manifold and fouls up exhaust valves and make them stick open then repair shops would be rich on fixing this problem iem not saying you dont know what your talking about i am just saying your just slightley off on the info (no insult intended)

@Socoolscienceshow a diesel engine compresses the gas into a tiny space even tinier than a gasoline engine and makes it explode by moving the molecules of the gas around so fast that it ignites and thats what they call the power stroke

chevytrucker1 3 months ago
@chevytrucker1 I don't know the answer to that question. But you can travel more miles with a gallon of diesel than with a gallon of petrol. In the UK, even though diesel is more expensive, it proves more economical in the long run as you can do more miles with the same quantity of fuel.
JackMacyntire 3 months ago
@chevytrucker1 Because manufcturers know that people want it, so they can make more money out of people. Greed is the answer.
urbex2007 3 months ago
@JackMacyntire Trucking companies use diesel trucks primarily because they have more torque at lower rpm than a petrol engine would have. The more torque you have the more towing capabilities you have. You're thinking of horsepower when thinking of diesels as not being "powerful". But you are definitely correct that they are much more efficient engines!
