Internal combustion engine

摘要

An internal combustion engine includes a combustion chamber defined by a cylinder, a piston defining a piston top, a cylinder head with an intake port and an exhaust port, and a corresponding intake valve and an exhaust valve. The internal combustion engine further includes an intake manifold for supplying air to the combustion chamber and an exhaust manifold for drawing exhaust gas from the combustion chamber. The flow dynamics of the internal combustion engine are improved by including textured surfaces on one or more of the piston top, the cylinder head, the intake valve, the intake port, the exhaust valve, the intake manifold, the exhaust manifold, or the fuel supplier. The textured surface may include indentations, protrusions, or combinations.

1. An internal combustion engine comprising:
at least one cylinder; at least one piston received in the at least one cylinder; at least one cylinder head coupled to the at least one cylinder defining at least one intake port and at least one exhaust port; a combustion chamber defined by the at least one cylinder head and a top of the at least one piston; at least one intake valve corresponding to the at least one intake port; at least one exhaust valve corresponding to the at least one exhaust port; an intake manifold adapted to supply air to the combustion chamber; a fuel supplier comprising one or more fuel injectors or one or more carburetors adapted to supply fuel to the combustion chamber; and an exhaust manifold adapted to direct a flow of exhaust gas from the combustion chamber, wherein at least one of the at least one cylinder head, the at least one intake valve, or the at least one exhaust valve includes a surface comprising a plurality of surface features arranged in a matrix pattern, wherein a center of each one of the plurality of surface features on the surface is spaced apart from a center of another one of the plurality of surface features on the surface.
