摘要： An engine (112) with an exhaust pathway air injection system includes a combustion chamber (342) having an exhaust port (250) and a crankcase (312) having an opening formed in the crankcase (312). The opening is designed to allow pressure pulses from within the crankcase (312) to be received through the opening. The engine (112) also includes an air pump (310; 414; 510; 610) having an inlet (322; 512; 612), an outlet (324; 514; 614), and a pumping mechanism. The air pump (310,414,510,610) is attached to the opening formed in the crankcase (312). Pressure pulses power the pumping mechanism. Additionally the engine (112) includes a manifold (254; 346) attaching the exhaust port (250) and the pump outlet (324,514,614).

摘要： An automatic choke apparatus (54) for use in an internal combustion engine (10). The choke apparatus (54) includes a choke valve (18) automatically operable in response to the speed of the engine, a thermally conductive assembly that conducts heat from exhaust gases produced by the engine (10), a thermally responsive member (118) in thermal communication with the thermally conductive assembly (66), and a mechanism (62) that moves in response to the thermally responsive member (118) to cause the choke valve (18) to remain in at least a partially open position during engine starting when the thermally responsive (118) member senses a temperature above a predetermined temperature. The thermally conductive assembly at least partially surrounds the path of the exhaust gases.

摘要： An internal combustion engine (16) having a centrifugally-responsive vacuum release mechanism (14) that relieves a vacuum within a combustion chamber (106) during the expansion stroke of an engine (16) at engine starting speeds. The vacuum release mechanism (14) is disposed adjacent to a cam (10) and engages a cam follower (34) at engine starting speeds to unseat an engine valve (82) while an engine piston (90) is moved toward a crankcase (98) and away from the combustion chamber (106). When the engine rotation speed reaches a desired kick-out speed, the centrifugal force transitions the vacuum release mechanism (14) from an engaged position to a disengaged position. The vacuum release mechanism (14) engages the cam follower (34) to separate the cam follower (34) from the cam (10) when the vacuum release mechanism (14) is in the engaged position. When the vacuum release mechanism (14) is in the disengaged position during normal operating speeds, the cam follower (34) is permitted to contact the cam (10) throughout the entire rotation of the cam (10).
