Abstract
Several embodiments of fuel injection controls for two-cycle crankcase compression internal combustion engines. In each embodiment, the fuel injection is controlled by measuring the amount of air inducted through measurement of the pressure generated in the crankcase. In each embodiment, abnormal pressure variations in the crankcase not due to the amount of air inducted are eliminated by measuring the pressures at predetermined crankshaft angles. In some embodiments, this is done through the use of a valving arrangement and in other embodiments, this is done electronically.
