ABSTRACT:
An internal combustion engine includes a mechanism for releasing compression from the cylinder during starting. That mechanism has an actuator attached to the engine camshaft for sliding between first and second positions. In first position the actuator is engaged by a lifter to open the engine exhaust valve during the compression phase of the combustion cycle. At the second position, the valve lifter does not engage the actuator and the exhaust valve remains closed during the compression phase. A weight lever is pivotally attached to the camshaft and drives the actuator between the first and second positions in response to engine speed. At slow speeds occurring while before the engine starts, the actuator is held the first position so that the compression is relieved. After the engine starts, centrifugal force causes the weight lever to drive the actuator into the second position at which normal compression occurs.
