ABSTRACT:
An improved gas injection system for uniflow dual fuel engines having a plurality of cylinders, a piston in each cylinder, inlet ports arranged around each cylinder to be uncovered by downward movement of the piston in the cylinder is disclosed. It is comprised of a seal located in one inlet port and a reed valve assembly connected to the inlet port via the seal. An inlet pipe connected to the reed valve assembly is adapted to be connected at its distal end to a gas source. An air inlet pipe is connected between the port seal and the reed valve assembly for feeding air therebetween such that when the piston closes the one inlet port, air from the air inlet pipe will close the reed valve to prevent further flow of gas.
