  • Poly valve system for internal combustion engines having non-parallel valve arrangement
    Patent number: 6457444
    Abstract: A poly valve system for an internal combustion engine having at least one cylinder having a bore and a cylinder center line, a piston capable of reciprocal travel within the bore, a cylinder head adjacent the bore having a hemispherical cylinder roof, intake and exhaust manifolds, and a combustion chamber defined between the cylinder head and the piston, comprising a plurality of independently operated valves. Valve seats comprise openings in the cylinder head between one of the manifolds and the combustion chamber. Poppet valves are situated in the valve seats to selectively allow communication between one of the manifolds and the combustion chamber. The valves are independently operable by a control signal, are non-parallel, and are oriented toward the cylinder center line.

  • Poly valve system for internal combustion engines
    Patent number: 6443111
    Abstract: A poly valve system for an internal combustion engine having at least one cylinder having a bore, a piston capable of reciprocal travel within the bore, a cylinder head adjacent the bore, and a combustion chamber defined between the cylinder head and the piston, comprising a plurality of independently operated valves. Intake and exhaust manifolds are located adjacent to the cylinder head. Valve seats comprise openings in the cylinder head between one of the manifolds and the combustion chamber. Poppet valves are situated in the valve seats to selectively allow communication between one of the manifolds and the combustion chamber. The valves are electrically, pneumatically, or hydraulically operated so that each valve, including one of several intake valves per cylinder, may be operated independently of each other.
