Diesel engines vs petrol engines:

  • Spark Ignition (Petrol Engines): In petrol engines, the ignition process begins with the introduction of an air-fuel mixture into the combustion chamber. A spark plug then generates a high-voltage electrical spark, which ignites the compressed air-fuel mixture, initiating combustion. This method is known as spark ignition, as the spark plug plays a crucial role in igniting the mixture.

  • Compression Ignition (Diesel Engines): Diesel engines operate on a different principle known as compression ignition. In these engines, air is compressed within the combustion chamber to a high temperature and pressure by the upward movement of the piston. This compression causes the diesel fuel, injected into the combustion chamber, to ignite spontaneously without the need for a spark plug. The high pressure and temperature created during compression cause the diesel fuel to combust, driving the power stroke of the engine.
