Unlike gasoline engines that are spark-ignited, diesel engines are compression-ignited. These engines spray highly pressurized diesel into compressed air causing ignition that eventually leads to power stroke. In earlier days, these engines were much noisier, inefficient, and produced much emissions. However, diesel engines were greatly improved in the 1980s and now they are more efficient than ever. In this regard, let's explore how a diesel engine works. Working Mechanism Explained Petrol and diesel engines share many similarities in terms of components with slight differences such as the presence of the spark plug in the former. This makes all the difference in regard to how the fuel is ignited. While in petrol engines air-fuel mixture is ignited by a spark, in diesel engines it's ignited by compression. The Compression ratio of diesel as compared to petrol in ICE engines is 20:1 and 9:1 respectively. The high compression ratio in diesel engines helps to generate the muc ... read more
