Such plug is needed in order for the engine to start. Diesel engine, on the other hand, acts by utilizing the natural process of fuel compression for combustion to begin.

    Apart from the difference in action, petrol engine and diesel engine differ in terms of effect to the vehicle’s function. Diesel engine is known to function with higher efficiency, especially in terms of fuel usage. This can be supported by the fact that diesel enhances lubrication and does not destroy the consistency of the engines function. Petrol engines, however, obtain the capacity of being light and permits drivers to handle vehicles at an easier and more convenient pace.
