Difference Between 2 Stroke Engine vs 4 Stroke Engine!

The debate over which engine is better, the two-stroke or the four-stroke is everlasting, so here are some differences between the engines that you might help make up your mind!

A two-stroke engine is a type of internal combustion engine which completes a power cycle with two strokes of the piston during only one crankshaft revolution.

  • A compression stroke compresses the fuel which then explodes.
  • The return stroke, called the power stroke, is driven by the exploded fuel. It moves the crank case, releases exhaust gases, and lets in new fuel and air for the next stroke.

A four-stroke engine on the other hand requires four strokes of the piston to complete a power cycle.

  • The compression stroke compresses air and fuel.
  • The power stroke. The compressed air is ignited, driving down the piston which turns the crankshaft in the process as well as providing enough energy to drive the other three strokes.
  • Exhaust stroke. As the piston moves up, it releases exhaust gases through the exhaust valve.
  • Intake stroke lets in a new supply of fuel and air for the first stroke.

Here is a video that highlights the major differences between a two stroke and a four stroke engine!
