Title:
DEVICE AND METHOD FOR CONTROLLING TIMING AT WHICH IGNITION IS STOPPED WHEN INTERNAL COMBUSTION ENGINE BECOMES STOPPED
Document Type and Number:
WIPO Patent Application WO/2010/067536
Kind Code:
A1
Abstract:
A control device for stopping an engine, configured in such a manner that, when, after the ignition of the engine is turned off, the throttle valve is opened to introduce air in order to avoid that a piston stops near the top dead center, the control device stops the engine without causing a misalignment of the stop position of the piston and without degrading emission quality. A device for controlling the timing at which ignition is stopped when an internal combustion engine becomes stopped is provided with: a means for sending, depending on the rotational speed (NE) of the internal combustion engine detected by a rotational speed sensor decreasing to a level lower than or equal to a predetermined value (Np) after the ignition (55) is turned off and the throttle valve (14) is closed, a signal to an actuator (18) so that the throttle valve (14) is opened in order to control the stop position of a piston; and also provided with a means for stopping the ignition of the ignition plug when the throttle valve (14) becomes opened in order to control the stop position of the piston.
