Internal combustion engine

Claim 1

An internal combustion engine having a cylinder and a piston within the cylinder for reciprocating movement between top dead center and bottom dead center in order to drive crankshaft through a 360° rotation, comprising a fuel injector for charging the cylinder with fuel, an oxidizer injector for discharging an oxidizer into the cylinder, a spark plug for igniting the fuel and the oxidizer to produce combustion that establishes a power stroke for each full rotation of the crankshaft, an exhaust valve for enabling a portion of said combustion products to be discharged from the cylinder, a distributor, piston position sensing means fixed relative to said distributor for initiating the discharge of the fuel and the oxidizer into the cylinder when the piston is at top dead center and further fuel and oxidizer sensing means associated with said distributor to terminate said fuel and oxidizer discharge into the cylinder as the piston moves from top dead center to bottom dead center, said further fuel and oxidizer sensing means being movable relative to said piston sensing means in order to selectively vary the length of time that the fuel and oxidizer are injected into the cylinder, and ignition sensing means in said distributor for initiating spark ignition within the cylinder, said ignition sensing means being movable relative to said piston postion sensing means in order to initiate said power stroke after said fuel and oxidizer discharge into said cylinder has terminated a stop fixed in position relative to the distributor, speed governor sensing means associated with said distributor for registering the engine speed, and speed governor means fixed in position relative to said position sensing means for engaging said stop and arresting relative movement of said stop and said speed governor means.
