摘要： In a process of automatically stopping a diesel engine upon fulfillment of automatic engine stop conditions, an ECU cuts off fuel injection when the engine speed equals a preset first engine speed N1.

摘要： 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.

摘要： The invention relates to a method for switching off an internal combustion engine and to an internal combustion engine suitable for carrying out said method. Here, after a switching off command for an internal combustion engine, the throttle valve in the air intake system is again opened to enable a relatively large amount of fresh air to be sucked into the combustion chambers of the internal combustion engine. This considerably increases the gas forces in the combustion chambers while the engine slows to a standstill, so that the internal combustion engine can be switched off in a controlled manner. At the same time, products of combustion, which may possibly still be present, are removed from the combustion chambers of the internal combustion engine. As a result, the preconditions for directly starting the internal combustion engine without a starter are created.

摘要： A stop control apparatus (100) for an internal combustion engine performs stop control of a three-or-less cylinder internal combustion engine (200). The stop control apparatus for the internal combustion engine is provided with: a determining device (161) configured to determine a compression stroke immediately before the internal combustion engine stops; and a throttle valve controlling device (168) configured to control an opening degree of a throttle valve (208) to be a predetermined opening degree while an intake valve (211) is closed in all cylinders, in the compression stroke immediately before the internal combustion engine stops, which is determined by the determining device. This reduces an influence of an intake negative pressure in an intake stroke, and makes it possible to preferably control the crank angle when the engine stops, even in the three-or-less cylinder internal combustion engine.

摘要： An automatic choke apparatus for a carburetor includes an electric actuator, a choke valve opening/closing mechanism configured to open and close a choke valve by being driven by a power exerted by the electric actuator, and a controller configured to control operation of the electric actuator. The controller, to which a battery supplies electric power, operates the electric actuator and the choke valve opening/closing mechanism in order that, when the engine is stopped, the choke valve is set in a semi-opened position and, when the engine starts to be cranked, the choke valve is set in a fully-closed position. Accordingly, it is possible to prevent the choke valve from freezing up in the fully-closed state in a case where the engine is stopped under an extremely low temperature environment.
