Otto cycle is a four-stroke combustion cycle used in spark-ignition engines.

• It consists of four processes: intake, compression, power, and exhaust.

• During the intake stroke, the fuel-air mixture is drawn into the cylinder.

• In the compression stroke, the mixture is compressed to a high pressure and temperature.

• The power stroke is where the spark plug ignites the mixture, causing it to expand and push the piston down.

4 stroke engines have separate intake, compression, combustion and exhaust strokes while 2 stroke engines combine intake and compression strokes and combustion and exhaust strokes.

• 4 stroke engines are more fuel efficient and produce less pollution than 2 stroke engines.

• 2 stroke engines are simpler in design and have fewer parts than 4 stroke engines.

• 2 stroke engines have a higher power-to-weight ratio than 4 stroke eng...read more
