摘要: To achieve an intermediate lock state in a short period when an engine is stopped and improve the accuracy of confirmation of the intermediate lock state, an engine valve timing control apparatus includes a variable valve timing mechanism configured to vary engine valve timing, and an intermediate lock mechanism configured to restrict relative rotation positions of a first and a second rotor of the valve timing mechanism at an intermediate lock position for starting the engine. Upon detection of an engine stop request, the valve timing mechanism and the intermediate lock mechanism are driven and controlled for establishing an intermediate lock state. When a predetermined period from detection of the engine stop request has expired without detecting the intermediate lock state within the predetermined period, an engine stopping process is executed. Even after the engine stopping process has been executed, monitoring of the intermediate lock state is continued.

摘要: An internal combustion engine and control method therefor in which the engine is selectively started by combustion without cranking. The temperature in the combustion chamber of an engine cylinder is stabilized upon starting of the engine, thereby allowing secured staring without cranking. When predetermined idling stop conditions (or engine stop conditions) are established, the temperature in the combustion chamber is estimated based on engine operating conditions read before such establishment, and the period of maintaining a engine rotational speed in a predetermined low range before stopping the engine is calculated or estimated based on the estimated temperature in the combustion chamber. The engine is then stopped after the calculated or estimated period of maintaining the engine rotational speed in the predetermined low range.

摘要: Embodiments are disclosed to reliably carry out engine starting without cranking. Using an internal combustion engine 1, when an idle stop condition is established, a third path switching valve 28 that is provided at the connection of the compressed air supply path 25 and a first blow-by path 21, and a blow-by control valve 24 are “closed”. The connection of the crankcase to the inlet path 14 is blocked, idling for a designated time is carried out, and finally the engine is stopped. On the other hand, when the idle stop release condition is established, an inlet valve 8 is “opened”, and the first to third path switching valves 26 to 28 are “closed”, thereby operating a compressor 17 for a designated period of time. Compressed air is thereby supplied to the combustion chamber 2 and the crankcase via the compressed air supply path 25, allowing an increase in the internal cylinder pressure. Finally, the engine is started.

摘要: An engine starting control apparatus is basically provided with a motor control section, a valve timing control section and a start control section. The motor control section is configured to operate an electric motor to crank an engine with an output of the electric motor being adjustable. The valve timing control section is configured to operate a variable valve operating mechanism when the engine is started to change at least a close timing of an intake valve of the engine from an initial timing to a start timing such that the start timing is set closer to an intake bottom dead center during a single engine start as compared to the initial timing. The start control section is configured to adjust the output of the electric motor as the close timing of the intake valve changes from the initial timing to the start timing during the single engine start.
