bullshit.... hate this video. I have assignment 'bout this for my school.. Damnnn :(
-
@Anoshh50 chemistry? shouldn't it be physics?
-
Wrong title. This is only one type of a 4 stroke engine, spark-ignition, there is also compression-ignition engines.
-
i have a question: if the exhaust spring stays uncompressed(valve shut) or doesn't open fully, will this give a compression issue causing the engine not to fire?
-
I have a question: What about the vacuum in the crankase, when the piston moves up??
vaccum in crankase = Makes it difficult for the piston moveing up ?? Am i wrong?
-
@Anoshh50 lol :D hey i have a tip you can use ethanol on engines :D loololol

@Nickers518 Yes,but the camshaft needs to spin first before the pistons go up and down to turn the crankshaft. in order for the crankshaft to rotate, the camshaft has to open the valves so how is it possible for the pistons to turn the shaft. So what starts the process if the camshaft spinning?
-
@cop083 The camshaft is what moves the valves. the crankshaft spins the camshaft, they are connect by a chain or belt.
-
@cop083 14.7:1 - 14.7 pounds of air to 1 pound of fuel(gasoline). that is the best mixture for maxium combustion.
you just did my chemistry homework :)

For every one who was wondering, the piston probably wouldnt have enough momentum by itself to complete the compression stroke . But the crank shaft (rod it spins) is connected to a weight called a flywheel that keeps the momentum. This is a REALLY basic diagram that shows only the piston and few other parts.
