A motor car engine is an Internal Combustion Engine (ICE). Energy is created by burning either diesel or petrol in a combustion chamber. In such an engine, the energy is transferred from the pistons moving up and down at high speeds. This up-down motion is converted to a rotary motion through the crankshaft and axle.
Why does a car's engine get hot? Why does a car's engine get hot when it is running? A car's engine is not efficient. The engine works by converting chemical energy in the form of fuel to the mechanical energy (work) that drives the wheels and makes the car move. But only about 20 to 30 percent of the chemical energy is actually converted to mechanical energy.
