Petrol Engines

Petrol vs Diesel engines and fuel efficiencyPetrol engines are generally quieter, smaller and utilise an internal combustion system within which means that fuel and air are pre-mixed together before being injected into the engine and ignited by spark plugs.

Diesel Engines

Diesel fuel is a mixture of hydrocarbons taken from petrol fuel and can be ignited without a spark due to air compression in the engine.
