Abstract
An internal combustion engine has a cylinder block that defines a blind cylinder bore that terminates within the cylinder block. A piston is positioned within the blind cylinder bore. The piston is connected to two crankshafts. A combustion chamber is formed between the piston and the blind end of the cylinder bore. Various mechanisms can provide actuation, timing control, and during control of valves that control flow into and out of the combustion chamber.
Claims20
An internal combustion engine comprising a cylinder block, the cylinder block defining a cylinder bore, a piston capable of reciprocating within the cylinder bore between top dead center and bottom dead center, a combustion chamber defined above the piston within the cylinder bore, an intake passage extending into the combustion chamber, an intake port defined at a junction of the intake passage and the combustion chamber, an exhaust passage extending from the combustion chamber, an exhaust port defined at a junction of the exhaust passage and the combustion chamber, an intake valve that opens and closes the intake port, an exhaust valve that opens and closes the exhaust port, the piston driving a crankshaft, the crankshaft driving a cam assembly, the cam assembly controlling movement of the intake valve and the exhaust valve and having a worm gear such that the cam assembly is configured to control at least one of valve timing or valve duration.
