fuel-air mixture

fuel-air mixture

The fuel-air mixture denotes a combination of fuel and air within a certain range of proportion. It is chemically correct when there is enough air in the mixture to burn up the present fuel completely. Normally, it is 1:15 by weight. There are three types of fuel-air mixtures: normal, lean, and rich.
