INCREASED DURATION INTAKE CAMSHAFT WITH DWELL AT PEAK LIFT

摘要

An internal combustion engine includes a cylinder block that defines a cylinder and a cylinder head mounted to the cylinder block. A reciprocating piston is arranged inside the cylinder for compressing a mixture of air and fuel. A crankshaft is arranged in the cylinder block and rotated by an application of combustion force on the piston. An intake valve is operatively connected to the cylinder head and controls delivery of the air to the cylinder for combustion therein. A mechanism provides a constant peak lift of the intake valve over an angle of rotation of the crankshaft that is at least 5 degrees, i.e., an extended dwell at peak lift. A vehicle having such an engine is also disclosed.
