What is Four Stroke Engine?
A four stroke engine is a type of internal combustion engine used to power motor vehicles. Most automobiles in the world today used the four stroke engine. Four stroke refers to the number of steps the engine takes in order to create energy. These four steps are namely:

  1. Intake ‘“ In this step, the piston located inside the engine goes in  downward motion which reduces pressure internally and draws in fuel and air.
  2. Compression ‘“ in this step, the intake and exhaust vales close, and the piston moves back up, compressing the air and fuel mixture.
  3. Power ‘“ as the air and fuel is put under great pressure, it is then ignited either by a spark plug or simply by the heat generated by the compression, which in turn forces the piston back down with great force, producing torque and power.
  4. Exhaust ‘“ After the power step, the exhaust valve is then opened where the used up fuel and air mixture is released.

The four steps are repeated over and over again, and the power generated from the four stroke engine is the power that drives vehicles.

German Engineer Niklaus Otto was the first person to produce a car with a four stroke engine, which explains why this type of engine is also referred to as the Otto cycle or Otto engine. A patent however was applied for, for the very first four stroke engine in 1861 by Alphonse Beau de Rochas, a French engineer, 16 years before Otto did.
