Abstract

A mass flow, timed fuel injection system is provided, wherein fuel flow is maintained at all times in a predetermined relation to air mass flow actually entering the engine at any instant, and the fuel injection valve is maintained open for an interval corresponding to a constant crank angle. This interval is corrected to compensate for any error which may have occurred because of inaccuracies introduced by the venturi through which air is metered and to compensate for the variations in discharge nozzle downstream pressure that occur in the induction ports.
