STOP CONTROL DEVICE FOR ENGINE

摘要

A stop control device for an engine can suppress vibration of the engine in the stopping of the engine and at the same time prevent a collision of a valve element of an intake restriction valve. The stop control device has the intake restriction valve (13) provided in the intake path (11) of the engine (1) in an openable and closable manner and capable of opening and closing the intake path (11), and also has control means (14) for controlling the intake restriction valve (13). In the stopping of the engine (1), the control means (14) controls the intake restriction valve (13) such that the intake restriction valve (13) is closed quickly to a predetermined opening degree near a totally closed position and also such that, when the intake restriction valve (13) reaches the predetermined opening degree near the totally closed position, in order that a large impact is not generated when the intake restriction valve (13) closes the intake path (11), the intake restriction valve (13) is closed more slowly to the totally closed position than when closed to the predetermined opening degree near the totally closed position.
