@fd3srules: The 13b that is used by the Rx7 is turbo changed or twin turbo charged and for Rx8's its N/A. So the rx8 is less powerful.. the name 13 in the 13b is the displacement of the engine which is 1.3L. If I am not mistaken the engine in the Rx8 can be run on hydrogen.. =]
This comment has received too many negative votesshow
A guy who sells performance parts out of japan told me that the rx8 is a 1.3L turbo rotary engine. And that if it was just rotary it would have like 40hp and that it had to be turbo rotary in order to get the 238 horsies. He said its a built in factory turbo. And to increase your HP by 25 or so u can change the factory turbo PSI settings up a few PSI and safely increase your HP from your stock engine. Thoughts? I looked around not sure what to think? thanks guys
how does each outer shell piece connect? each section he attached was never bolted together, and also wheres the gaskets between each piece? I never saw any Orings? what are there LONG ass bolts that go through the whole side to clamp all 5 sections together?
There are gaskets, indeed. If you look carefully, you will see a red o-ring nearest the rotor, and a black o-ring on the outer perimeter. These are the gaskets!
who knew??? that was really an eye opener for me. im used to tearing apart american pushrod v8's. amazing how those things acctually work. ive been looking at them for a while now and im trading my cobra in on an rx8 in the morning. time for a change.
and for that point, forget saving the environment. i don't litter or anything, but for every person trying to save the environment, there's probably 10 more people destroying it somehow. if you drive a yaris and pull up to a 68 GTO with valves incorrectly adjusted, pouring smoke out the back end of its 400ci V8 engine, do you think you're saving the environment as much as he's killing it?? NOPE!
batterys are a piss poor way to power a car. thats why the batterys in most hybrid cars weigh hundreds of pounds, yet can barely top 100mph and can only hold a charge for a day or two.
You just proved you dont know that much about electricity.. Given enough volts an electric engine could theoreticly move an object close to the speed of light.. Theres no explosion that would come close to that.. We simply cant make an engine strong enough to hold such power so we're still stuck with the old fuelcrapajack..
in order to produce high power from elec u need higher voltage yes
but it's not just the engines fault that it cant handle 60,000 volts being shoved up its arse and run at like 3 million rpm and imagine the E.M.R from a E motor like that, we'd all get cancer
the problem is finding a small, light, cheap and effective battery capable of supplying such immence power.
i just can't wait to know more about this hydrogen rotary engine mazda r apparently working on, when u burn H2 u get water vapor
anyhow, anything involving Carbon produces CO2 when burned wich will make the UV-radiation to stay inside our atmosphere. H2 is the ultimate fuel because it produces 432kJ/mol and the only thing that comes out of it is H2O.. Theres a problem however to keep the H2 in liquid form, and/or bound to a metal wich means you could maintain the H2 inside the metal at room temperature. The problem here is that H2 is covalent and needs to be in ionic form to bound with a metal.
yeah the only "safe" method is bound to metal as otherwise ur screwed in a crash. no 1 needs supercold liquid H2 spewing out of a tank especialy near an ignition source
but as for the chemical bonding method i think U.N have hit the nail on the head. google united nuclear smart tank, they even sell them with H2 chargers but it takes like a week to make enough to fill your car
and on the H2 note the rotary is the best engine for it, only thing better is jet turbine because of the H2 burn speed
electric power is measured in amps and voltage. 60000 volts and 1 milliamp is 60 watts, as much power a light bulb needs. an AC induction electric motor can use just about any combination of voltage and amperage depending on the design. the series wound electric motors in trains produce great power at great efficiency and they dont require huge voltages or much maintenance and have been used for decades. the rotaty engines are good but electric power is always better and far more efficient.
not sure on the weight but alot of the wheels on a train have the motor connected directly to them. no gear box or anything, even a a manual transmission wastes alot of energy. as the train accelerates, the series wound motor (especially) uses less and less electric power until it reaches maximum speed, automatically without a gear box! drawing just enough to keep the train moving at that speed. how much does a carriage weigh compared to the electric motor the size of a microwave oven? not much.
Well, batteries are strong, but electricity is not the way. A Prius polutes more than a hummer H2 can (in a year or two, cant remember) because of how the batteries in the prius's are put together. They polute much!
If you define efficiency in terms of how much fuel is burned in relation to the size and power output of the engine, the rotary kicks the ass of most other engines around right now including piston engines. If you are talking about how much fuel per hour is burned for a given amount of power, the rotary loses. But it's quickly made up for when you get into 3 or 4 rotor engines.
in comparison to other engines of similar size (would be put in 4.0L class due to the way a rotary works) it is much more efficient when you look at the amount of power:fuel consumed. As for the actual amount of fuel consumed it depends on the vehicle the engine is in. In a standard mazda cosmo you'd probably expect to get around 15-17mpg in combo city/hwy driving.
If you can afford the RX-7 or RX-8 you can pay for the gas. I would rather put precious gas in a Rotary engine than a Fuel economical POS. Rotary for life
you will be suprised, eventually rotary engine and economical will no longer be mutually exclusive as they perfect the engine. Eventually u might see it in one's family hatcback...
marek0086 a wankel has smaller size more hp than a piston engine, it's way lighter than other engines,it has less vibrations, it cost less than a same output PE,
cause it's light the car can have a better weight distribution so u can touch the 50-50 weight.
It's the future engine when it will need less gas than now :P
