ENHANCED PERFORMANCE POPPET VALVES FOR INTERNAL COMBUSTION ENGINES

摘要

A valve arrangement for an internal combustion engine having at least one intake valve, at least one exhaust valve, and at least one reciprocating piston. Each intake valve is seated in the cylinder head at a lesser distance from the piston than is each exhaust valve. Also, each exhaust valve has a cross sectional area less than seventy percent of the cross sectional area of each intake valve. The cross sectional area of each exhaust valve may be for example sixty to sixty-two percent of the cross sectional area of each intake valve.

1. An internal combustion engine comprising an engine block containing at least one cylinder and at least one piston translatably in each one of the at least one cylinder, and a cylinder head at one end of each one of the at least one cylinder, the cylinder head including, for each cylinder, at least one intake valve, an intake valve seat for each intake valve, one exhaust valve for each intake valve, and an exhaust valve seat for each exhaust valve, wherein the intake valve seat is located a lesser distance from the piston than the exhaust valve seat.
