A Technique to Characterize Quantitatively the Air/Fuel Mixture in the Inlet Manifold of a Gasoline Engine 690515

This paper discusses in detail a new technique for air-fuel mixture entering individual cylinders of a multicylinder engine. The method described provides estimates of the weights of both air and fuel entering individual cylinders and the proportions of the fuel that are present as liquid at points just upstream of the inlet valves. The technique has been developed for steady-speed conditions and is not applicable to transient operating conditions.
