Diesel engine or Petrol engine

Petrol Engines use spark plugs to create the required amount of temperature, to ignite the fuel because the firing temperature of petrol is very high around 280 degrees C. Spark Plug creates a spark for a small instance and that helps to create the power stroke.Diesel Engines are also called compression ignition engines. This cycle is based on Diesel Cycle. The name Diesel is given by its inventor Rudolf Diesel.
