ABSTRACT OF DISCLOSURE Disclosed herein is a rotary internal combus- tion engine comprising a housing assembly defining a rotor cavity including a peripheral wall and an inlet for admitting a fuel-lubricant mixture into the rotor cavity, a rotor located for rotation in the cavity and including a plurality of apex portions in engagement with the peripheral wall so as to create in the cavity and in response to rotor rotation a substantially sealed rotating chamber which, during one portion of the rotor rotational cycle, increases in volume so as to provide inflow through the fuel inlet and into the ro- tating chamber of a fuel-lubricant mixture, which, during a second portion of the rotor rotational cycle subsequent to the first cycle portion, decreases in volume to compress the fuel-lubricant mixture in the rotating chamber, and which, during a third portion of the rotor rotational cycle subsequent to the second cycle portion, increases in volume in response to fuel ignition in the rotating chamber, an area to be lubri- cated, and a conduit extending between the rotor cavity and the area to be lubricated such that, in response to the compression of the fuel-lubricant mixture during the second portion of the rotor rotational cycle, fuel- lubricant mixture is pumped from the rotating chamber in the rotor cavity to the area to be lubricated.
