View source for Diesel fuel system

A '''diesel fuel system''' is used in [[Diesel engine]]s that are [[internal combustion engine]]s burning [[diesel]] oil rather than [[gasoline]]. Injectors are used to spray droplets of diesel oil into the combustion chambers, at or near the top of the compression stroke. 

Ignition follows due to the very high temperature of the compressed intake air, or to the use of "glow plugs," which retain heat from previous ignitions (spark plugs are not used). Diesel engines are generally more fuel-efficient than gasoline engines but must be stronger and heavier because of high compression ratios.
