A car engine uses a four-stroke cycle -- how can two strokes accomplish the same tasks? Learn all about the two-stroke engine, where it's used and how it compares to a four-stroke.

That piston does a PISTON of stuff!
Nice explanation 👍
Marshal I have seen many vids explaining 2 stroke engines. but I must say,ur video was the most explanatory and very simple. Thank You very much. Hope to learn much more from u, about 2 stroke. I am a rukee in this field having much interest in repairing my Yamaha RX100,2 stroke,91 model. Thank You:-)
A piston that acts like a piston...smart
One disagreement... 4-cycle small gas engines spark plugs will STILL fire at the top of the exhaust stroke. The coil and spark plug don't know what stroke the engine are on and will fire every time that the flywheel magnets pass the coil. No, it doesn't produce power, but the plug still "sparks"... Great video, though!
awesome video, basic, and that helps
Excellent. Thanks. I forgot and gave up remembering.
a great explanation
has twice the power? lol. no.
I have a grass cutting company and I make my living of 2 stroke engines.
greater...
thank you for the refresher course. got a problem saw I'm working on. spitting fuel back out carb. was thinking possible piston damage, after watching this refreshing my mind on the 2 cycles, I'm thinking clogged muffler. yes, 3 am here, I HATE troubleshooting just before bed!
What about the Reed Valve?
No coverage of how induction is managed, though. The graphic shows reed valve between carb and crankcase, but most chainsaws I've seen are piston-ported, which then casts the piston as the intake valve too. Nowadays, strato scavenging significantly boosts thermal/fuel efficiency and reduces emissions, as required by law. This sort of stuff might make it into V2.0?
The piston have 4 roles : intake valve, exhaust valve, compressor and he push the air/gasoline mixture in the combustion chamber.
okay lets say the engine is doing 6000 rpm. that's 100 times a second or 100 combustion cycles a second which means one revolution every .01 seconds which means the fuel needs to be burnt up in a less than .005 seconds before the intake charge comes in. i know fuel burns fast but it doesn't burn that fast.
So thats why you have to replace the top end more then 4stroles
Thank you sir :)
great presentation. but in MY opinion nothing beats the old chevy videos of transmission, diffs etc
