Here to assist. This video explains the different aspects of petrol also known as gasoline, and diesel engines.
Diesel and petrol engines work on the same four-stroke circuit.
Suction Stroke: The piston lowers and draws air into the cylinder and fuel is introduced. Compression Stroke: The piston moves upwards, compressing and heating the air and fuel that was sucked in it. Power Stroke: A spark plug can ignite hot air and fuel for the piston to move back into the cylinder. It’s the essence of the engine. Exhaust Stroke – Finally, the used up fuel and air are released out through an exhaust port, as the piston drives up. It is then time to start the cycle again.
Gasoline and diesel engines differ in how they ignite the fuel inside the cylinder. A diesel engine does not require a spark plug in order to ignite the compressed air and fuel. Instead, it is reliant upon compressing air and fuel to a self-ignition temperature.
It is the reason why diesel engines from petrol ones. For more information on the differences, watch the video at the link below.
