What Is The Difference Between A Four-Stroke & A Two-Stroke Engine?

Introduction

The difference between a four-stroke and two-stroke engine lies in the number of strokes each engine type uses to complete a single cycle of operation. A four-stroke engine completes one cycle in four steps—intake, compression, combustion and exhaust—while a two-stroke engine completes one cycle in only two steps: intake/compression and combustion/exhaust.

A four-stroke engine is a type of internal combustion engine.

A four-stroke engine is a type of internal combustion engine. It has four strokes: intake, compression, combustion and exhaust.

The first stroke is the intake stroke that occurs when the piston moves from bottom dead centre (BDC) to top dead centre (TDC). This draws air into the cylinder through an open valve at BDC and closes it at TDC.

The second stroke is called compression where the air/fuel mixture is compressed by rising pressure in order to increase temperature so as to ignite easily when exposed to heat generated during ignition process later in this same cycle; which happens when you squeeze down on your bike’s throttle while riding uphill or going fast downhill while pedaling hard on level ground too!

The four strokes are: 1) Intake, 2) Compression, 3) Combustion and 4) Exhaust.

The four strokes are: 1) Intake, 2) Compression, 3) Combustion and 4) Exhaust. This can be remembered with the phrase “Iccceeee”. The number of strokes is the same as the number of pistons in an engine.

The intake valve opens and allows air/fuel mixture into the cylinder while simultaneously pushing out any remaining exhaust gases left over from previous cycles. The compression stroke begins when all valves close at top dead center (TDC). This compresses both fuel-air mixture as well as existing gases inside each cylinder until ignition occurs on its own during next cycle’s power stroke–explosion! Finally comes another period where no movement occurs within an engine until exhaust valves open up again at bottom dead center (BDC).

A two-stroke engine is another type of internal combustion engine.

A two-stroke engine is another type of internal combustion engine. It’s called a “two-stroke” because it has only two strokes: 1) Intake, and 2) Combustion/Exhaust. A four-stroke engine can be thought of as having one extra stroke called “Compression”.

A two stroke engine has a higher power-to-weight ratio than a four stroke due to its simplicity, but it also produces more emissions (which means more air pollution) because there are no valves or spark plugs involved in its operation

Conclusion

The main difference between a four-stroke and two-stroke engine is the number of strokes used to complete one cycle. In a four-stroke engine, there are four strokes: intake, compression, combustion and exhaust. The intake stroke sucks in air and fuel into the cylinder; then the compression stroke compresses this mixture until it’s ready for ignition by spark plugs or other means (like glow plugs). Next comes combustion (where fuel burns), followed by exhaust where gases leave through an exhaust port on their way out of the engine. Finally there’s another intake stroke before starting over again with another cycle!
