In a petrol engine the combustion takes place when a petrol air mixture is compressed and ignited by an electric spark which forces the piston to move whereas in diesel engine only air is compressed rather than fuel and air mixture and at the end of the compression stroke the fuel is directly injected into the combustion chamber by a fuel injection pump.
