air-fuel mixture ratio

air-fuel mixture ratio
The ratio by weight of air and fuel in the mixture being sent into the cylinders of a reciprocating engine. Ideally, the ratio should be 15:1. Besides the ideal (stoichiometric) ratio, the air-fuel mixture may be rich or lean depending on the quantity of fuel in the mixture. With more fuel, the mixture is rich, and with less fuel, it is a weak or lean mixture.
