Abstract
Improvements in a fuel injected, internal combustion engine having a first passage for flow of air into the combustion chamber and exit of exhaust gases from the combustion chamber and a single poppet valve opened and closed in timed relation to rotation of the engine's crank shaft to control flow of gases through such first passage, an inlet air passage and an exhaust gas passage each communicating with the first passage and one another and a diverter valve movable in timed relation to operation of the poppet valve selectively to direct, in one position, air into the combustion chamber through the inlet passage and, in another position, exit of exhaust gases through the outlet passage wherein the improvement comprises a separate small passageway in parallel flow relation with the intake air into the combustion chamber which directs supercharged air into the combustion chamber when the diverter valve is in the exhaust position to purge the engine.
