Abstract:
A charge motion control valve for use with an engine of the type including an air intake port which branches into first and second ports which communicate with a cylinder, a fuel injector which injects fuel into said first and second ports, said engine further comprising a first intake valve which is operatively disposed within said first port and a second intake valve which is operatively disposed within said second port, wherein an amount of fuel condenses on said first and second intake valves during cold start conditions, said charge motion control valve being operatively disposed in said air intake port in relative close proximity to said first and second ports and comprising a first half which forms a first unrestricted area, effective to allow a first amount of air to enter into said first port and a second half which forms a second unrestricted area which is larger than said first unrestricted area and which is effective to allow a second amount of air to enter into said second port, said first and second amounts of air being effective to carry said fuel into said cylinder and to create turbulence within said cylinder, and wherein said first and second amounts of air being further effective to shear said condensed fuel from said first and second intake valves, thereby substantially vaporizing said condensed fuel.
