Air is drawn into the engine and compressed at high ratios, heating it up. Diesel fuel is then injected into the hot, compressed air, causing spontaneous ignition. This process leads to the expansion of gasses that drive the engine's pistons, generating power. Diesel engines do not use spark plugs. Instead, the fuel combusts on its own because of the immense pressure. Because of the way they ignite, the fuel, durability, and reliability are greater than in gasoline engines.
