Scavenge valve for a two-cycle engine |
摘要 |
A method and system, including a valve (32) for controlling the amount of fluid purged from a cylinder (12) of a two-cycle engine prior to the combustion of an air-fuel mixture within the cylinder especially during low demand periods of engine operation. The system including a throttle (26) disposed upstream of an inlet port (14) and controlled to be maintained in an open condition during such intervals. The valve (32), which is adapted to communicate with a scavenge port (30) includes a piston (80) that is movable relative to an aperture (76) in response to a pressure differential created in part by the operation of a cooperating electromagnetic valve (54), such that when the piston is moved to uncover the aperture a predeterminable amount of fluid within the cylinder can be purged therefrom as the cylinder piston is moved through its compression cycle.
