The diesel engine along with the thermodynamic cycle was created by Rudolf Diesel in the year 1897. A diesel engine is an internal combustion engine. It works by usuing the heat of compression to make ignition to burn the fuel. The fuel is injected into the combustion chamber in the last stage of compression. This is different from the petrol engine that uses spark ignition. The diesel engine is way more efficent and planet friendly.
