The Only Video You’ll Ever Need to Watch to Know how 4 Stroke and 2 Stroke Engines Work and Differ

I have given it my all to try an pack as much information as humanly possible and present them in a simple, coherent and understandable manner with the goal of creating what is the only video anyone needs to watch to learn how a four stroke and a two stroke engine work. The video also covers the differences, benefits and drawbacks of 2 stroke and 4 stroke engines and also answers the question of why the four stroke ultimately prevailed over the two stroke in most applications despite being larger, heavier, more expensive and more complex. Let’s start with the four stroke. Why is it called a four stroke? It’s because the four stroke engine needs four strokes to complete one combustion cycle. Every time the piston moves from top to bottom............. or vice versa............... that’s one stroke. One stroke of the piston equals 180 degrees of crankshaft rotation. Now the four strokes are: intake... compression..... combustion..... and exhaust During the intake stroke the piston trav
