How Two-stroke Engines Work
bicycles reviews | bicycles videos | bicycles online
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.

has twice the power? lol. no.

I have a grass cutting company and I make my living of 2 stroke engines.

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
-
i have always wondered this. THANK YOU now i have a better understanding of two strokes, i knew the utmost basics but this has made it very easy to understand and follow, also makes working on them a lot simpler. again, thank you.
-
why doesn't intake charge ignite on the way in?
-
Why aren't these used in cars?
-
Awesomely explained
-
thanks man
-
Great video
I'm now smart :) -
Yes, your presentation is easy to understand, but you neglected the two major issues with two-stroke: 1, It throws unburned fuel into the air through the exhaust port, and thus, 2, It is terribly fuel inefficient.

true this guy presents stuff in laymans terms easy to understand and digest .theres none of that unnecessary what at times can seem like deliberate intent to complicate things and thus cause nothing but confusion.keep up the good work. these types of videos play a vital role in educating the public .

good and he let me understand every thing easily
