  • Cylinder head for internal combustion engines
    Patent number: 6098590
    Abstract: A cylinder head for internal combustion engines, particularly diesel engines with direct fuel injection, which has two inlet valves per cylinder each including spin-inducing means for producing spin flow about the longitudinal axis of the associated cylinder. Having regard to the direction of spin, the leading inlet valve is provided with an eccentric, crescent-shaped chamfer facing in the general direction of spin flow, and the trailing inlet valve includes flow blocking means for preventing combustion air from exiting the trailing inlet valve in a direction opposite to the direction of spin flow.
