Are two stroke and Four stroke carbs diffirent? - Bike Chat Forums What happens if I put 2-stroke fuel in a 4-stroke engine? 2 Stroke Vs. 4 Stroke Dirt Bike: Pros And Cons - TreMoto The main difference is the oils viscosity. of the. How fuel and air enter and exit the chamber is crucial to this design. It takes four processes to burn fuel with each process comprising one stroke. The more cylinders an engine has, the more power it can generate. 2-strokes do make peak power at much higher RPM, but the shortened cycle allows the engine to reach high speeds in a much shorter period, effectively increasing throttle response. What Is a Four Stroke Engine? Once the piston reaches the top of the chamber, ignition occurs, driving it downward again with all valves remaining shut during the duration of both the compression and ignition strokes. Made with in Silicon Valley. series. The first difference is the fact that the spark plugs fire once every revolution in a two-stroke engine, and fire once every other revolution in a four-stroke engine.
