摘要： An improved cast cylinder head for a high performance internal combustion engine is provided by an especially configured quench surface from which a contoured combustion chamber extends having a metal mass buildup shrouding the exhaust gases through the exhaust valve seat. A metal mass buildup configuration is also provided about the intake valve seat which acts in conjunction with an especially configured and proportioned valve intake passage to draw the fuel-air mixture into the combustion chamber in an unshrouded, helical flow pattern. The intake passageway configuration is such that a rich fuel-air mixture is drawn through the intake valve seat at a portion thereof remote from said exhaust valve seat while a lean fuel-air mixture exits the intake valve seat adjacent the exhaust valve seat. Positioning the fuel-air mixture in such a manner in combination with the unshrouded metal mass buildup minimizes short-circuiting of the fuel through the exhaust valve seat in a valve overlap condition.

摘要： An improvement in a cast head for a high performance internal combustion engine of the type using wedge shaped combustion chambers where the opening of each combustion chamber includes an undulating curved edge portion extending inwardly towards a position between the two valve seats in the form of a generally V-shaped protuberance. A built up mass of cast material sloping from the protuberance towards the valve seats guides gases from the combustion chamber through the exhaust outlet primarily and, to a lesser extent, from the intake inlet into the combustion chamber. This velocity increasing mass of material adjacent the exhaust port of the combustion chamber increases the velocity of the exhaust gases through the exhaust port to improve breathing of the internal combustion engine.

摘要： An improvement in a cast head for a high performance internal combustion engine having a flat mounting surface for each of several in-line circular piston areas, a wedge type combustion chamber extending from the head mounting surface and defined by a flat quenching surface and a concave, contoured wedge-shaped cavity forming surface. This wedge-shaped cavity tapers outwardly from the quenching surface between a shallower portion adjacent the quenching surface to a deeper portion in which the valves are located. The cavity forming surface of the deeper area of the combustion chamber being provided with a general contour defined by two parallel intersecting, truncated cones generally concentric to the two valve openings in the wedge-shaped combustion chamber with a gradually contoured surface section between the cones at the deeper area of the combustion chamber and a velocity increasing protuberance in the combustion chamber at the shallower portion of the cavity which protuberance includes a curved edge portion of the flat quenching surface, which edge portion extends inwardly of the wedge shaped cavity toward a position between the two valve seats and a built up mass of cast material sloping from the curved edge of the quenching surface toward the valve seats to guide gases from the combustion chamber through the exhaust outlet primarily and, to a lesser extent from the intake inlet into the combustion chamber. This mass of material increases velocity through the exhaust port during the engine exhaust cycle.

摘要： A concave, multi-planed scooter for performing riding tricks having handles attached to at least one end of the scooter's generally concave riding platform for a person, who is supported by the platform and riding the scooter, to hold onto. The handles are angled such that a rider's feet are placed properly for a well-centered riding position. The improved scooter has a wheel assembly attached to the underside of the platform beam in a directional aligmnent that provides the various planar surfaces of the riding platform with relatively wider or relatively tighter turning radii. Moreover, the wheel assembly may be mounted by a pinion nut system that allows the scooter ease in steering and includes an adjustment lock-nut for tight or loose steering. The two center wheel assemblies may be mounted on wedge-shaped spacers that position the wheel assemblies away from the underside of the platform beam for better stability and shock absorption. The scooter also has a decelerator consisting of a decelerator seat and decelerator pad attached to the underside of the platform beam, which pad is easily replaced when worn by removal of a screw or other means for fastening the decelerator to the underside of the platform beam.
