Abstract: A new mechanism of Inlet Camshaft with valve lift varying infinitely for Internal Combustion engines is presented. In this, the valve opening and closing is done by a three-dimensional cam or camoid with a translating spherical follower. And the camoid is actuated by a Governor which rotates about a horizontal axis. Also, the design procedure for spring and analytical expressions for Governor are generated. And the design of camoid profile is defended by employing the theory of envelope. A numerical example is given to explain the application of the approach.
Keywords: Camoid, Governor, Variable Valve Lifting.
