  • Patent number: 7654574
    Abstract: A mud flap mounting system for connecting a mud flap to a mud flap mounting bracket of a vehicle includes a mud flap group and a mud flap mounting assembly for connecting one mud flap of the mud flap group to a vehicle mud flap mounting bracket. The mud flap group includes at least two mud flaps, each comprising a sheet of flexible material having a top edge and defining at least two mounting openings, each mounting opening including a bolt hole, a first slit and at least a second slit, said first slit being a severed portion of the sheet with virtually no loss of material and extending from the top edge to the corresponding bolt hole, and the at least a second slit extending outwardly from the bolt hole. The mud flap mounting assembly includes a pressure plate, a spring member, a bolt with a head and a shank with a distal end, and a tightening member.

  • Patent number: 7607413
    Abstract: An induction system for an internal combustion engine, having a combustion chamber and an intake port in periodic communication with the combustion chamber, includes an intake tube having a lower trumpet (41) and an upper trumpet (42), each having an upper end, a lower end and a length; a transition section (43) extending between the upper end of the lower trumpet and the lower end of the upper trumpet; wherein the lower trumpet is connectable at its lower end to the intake port (22) of an engine and has an inner transition diameter (48) proximal its upper end, and wherein the upper trumpet has an inner expansion diameter (55) that is between about 68 percent and 217 percent greater than the transition diameter.
