Do Gasoline and Diesel Engines Work Differently?

Differences Between Diesel and Gasoline Engines

Gasoline Engine Overview

Gas powered engines produce energy using a stroke combustion cycle. During the intake stroke, a controlled amount of fuel combines with air in a cylinder. A piston then compresses the fuel and air in the compression stroke. A spark ignites the mixture, creating a small explosion that forces the piston back up in the combustion stroke. Finally, the exhaust stroke allows the resulting gases to exit through the open exhaust valve. Engine components work in unison to create this chain reaction. Cylinders provide the spaces for gas and air to combine, while spark plugs enable the ignition of the compressed mixture. Valves open and close to let fuel in and exhaust out. Pistons move up and down in the cylinders to create the needed compression. Rings prevent escape/leakage. As the crankshaft transforms vertical movement to circular, a connection rod rotates at each end, connecting the crankshaft and piston. Surrounding the crankshaft, the sump holds motor oil.

Diesel Engine Overview

Different from a gas power plant that compresses the fuel-air mixture in the cylinders to create a controlled explosion, a diesel engine compresses air only. As the air is compressed, it reaches a very high temperature. This allows it to ignite atomized diesel fuel as that fuel is injected into the combustion chambers. The fuel is added relatively late in the combustion process, so the fuel-air mixture is unevenly distributed (heterogeneous). Therefore, the amount of fuel added rather than the air intake controls the torque the engine produces, and the air-fuel ratio is usually high.
