Poly valve system for internal combustion engines

A valve system for an internal combustion engine comprising at least one cylinder defining a bore for receiving a piston, a cylinder head adjacent to said bore, a combustion chamber defined within the bore between the piston and cylinder head, an intake manifold and an exhaust manifold adjacent to the cylinder head, valve seats in the cylinder head which each provide communication between the combustion chamber and one of the exhaust manifold and intake manifold, comprising:

• at least three intake valves associated with the cylinder for selectively controlling communication between the intake manifold and the combustion chamber, the valves each have a poppet located in one of the valve seats for selectively opening and closing communication between the intake manifold and combustion chamber through said valve seat, each valve is independently operated by a control signal.
