Abstract:
An internal combustion engine has a stator passage leading to a cylinder. An intake poppet valve is disposed between the cylinder and stator passage, and a rotary valve adjoins the opposite end of the stator passage. The rotary valve has a rotor with an elongated tapered rotor passage partially in registration with the stator passage. The rotor is driven by the crankshaft and is adjustable in phase to vary the time of opening and closing of the rotary valve, and is axially shiftable to vary the valve opening duration. A control system responsive to engine speed and load independently varies the rotary valve phase and duration for optimum engine operation.
Abstract:
A rotary valve is utilized to accomplish stratified charging of an internal combustion engine. The port in the valve communicates first with a source of non-enriched gases and thereafter with a source of carbureted gases during the intake or suction stroke. The valve is adjustable such that, as engine speed increases, the amount of carbureted gas fed to the combustion chamber is increased.
Abstract:
A fluid system of an engine which has an outwardly opening engine valve controls fluid delivery and removal from first and second cylinders for controlling the position of the engine valve and injection of fuel responsive to the position of the engine piston.
