Manifold intake arrangement for internal combustion engines

Patent ·
OSTI ID:6672938
This patent describes an internal combustion engine, comprising: a combustion chamber having a piston disposed therein; a pressure chamber; a first intake valve means for providing selective communication between the pressure chamber and the combustion chamber; a second valve means for providing selective communication between the pressure chamber and a fuel and air mixture supply; exhaust valve means for providing selective communication between the combustion chamber and the atmosphere, the exhaust valve means opening during the exhaust stroke of the piston and allowing spent gases to be expelled therethrough and closing at the end of the exhaust stroke; an intake control means connected to the first valve means for opening the first valve means during the intake stroke of the piston after the exhaust valve means is closed and maintaining the first valve open during an initial portion of the compression stroke for pressurizing the pressure chamber during the initial portion of the compression stroke and for closing the first valve means during the remaining portion of the compression stroke; wherein the second valve means opens during the intake stroke of the piston a period of time after the opening of the first valve means and closes during the compression stroke of the piston.
