Abstract
An internal combustion engine of the rotary type has a pair of connected pistons and provides increased power and fuel economy. The fuel combustion chamber includes a single-acting air inlet valve and a double-acting outlet valve. The oil cooling system delivers air through each of the pistons whereby the oil is recirculated after cooling.
Claims22
A rotary engine comprising:
- an engine block, said block defining an internal rotor cavity, a rotor, said rotor eccentrically positioned within said cavity, said block defining a combustion chamber, said combustion chamber positioned exteriorly of said rotor cavity and in fluid communication therewith, a pair of pistons, said pistons affixed to each other and slidably mounted within said rotor, an air inlet valve, said inlet valve positioned at one side of said combustion chamber, a dual acting outlet valve, said outlet valve comprising a top and a bottom rest, said outlet valve positioned at the other side of said combustion chamber, said combustion chamber defining both an outlet valve ceiling port and an outlet valve floor port, means to ignite fuel, said fuel ignition means located within said combustion chamber between said inlet and outlet valves, said block defining an exhaust port, said exhaust port spaced circumferentially from said combustion chamber and in fluid communication with said rotor cavity, said block defining an inlet port, and said inlet port circumfrentially spaced from said outlet port and in fluid communication with said rotor cavity.
A method of operating a rotary type internal combustion engine having a rotor with a pair of pistons positioned in an engine block cavity, the block defining a dome-shaped combustion chamber, said combustion chamber comprising an air inlet valve, said combustion chamber defining both an outlet valve ceiling port and a floor port, a double-acting outlet valve and a means to ignite the fuel, the method comprising the steps of:
- (a) turning the rotor whereby the first piston moves towards the combustion chamber while the inlet valve is closed and said outlet valve is seated within said dome ceiling port;
- (b) opening the inlet valve to allow air into the combustion chamber while maintaining the outlet valve open as the first piston continues to approach the combustion chamber;
- (c) closing the outlet valve by seating said valve in the combustion chamber floor port;
- (d) injecting fuel into the combustion chamber;
- (e) opening the outlet valve;
- and
- (f) igniting the fuel therein.
