Abstract: An oil supply control device for an engine includes: a hydraulic controller which outputs a control value to an adjusting device to cause a detected hydraulic pressure detected by a hydraulic pressure sensor to coincide with a predetermined hydraulic pressure value; a determination portion which compares an output control value output from the hydraulic controller to the adjusting device when the detected hydraulic pressure coincides with the predetermined hydraulic pressure value and a control value stored in a memory, to determine whether or not a difference between the output control value and the stored control value lies within a predetermined allowable range; and a device controller which allows activation of a hydraulic actuating device when an oil temperature is not lower than a first temperature in a case where the difference lies within the allowable range, inhibits activation of the hydraulic actuating device when the oil temperature is lower than a second temperature higher than the first temperature in a case where the difference does not lie within the allowable range, and allows activation of the hydraulic actuating device when the oil temperature is not lower than the second temperature in a case where the difference does not lie within the allowable range.

Abstract: A main lock member is fitted in a main lock bore at a main lock phase for closing an intake valve at a timing later than a timing when a piston reaches a bottom dead center, whereby a rotation phase is locked. In a subordinate lock mechanism, the rotation phase is locked at a subordinate lock phase advancing further than the main lock phase. In a lock control mechanism, a temperature sensing body is changed to an expanded state, whereby a moving member is latched at a first position in which the main lock member is allowed to be fitted in the main lock bore, whereas at a main lock phase in a cold stop state after a timing when the temperature of the stopped internal combustion engine becomes less than a preset temperature, the temperature sensing body is changed to a contracted state.

Abstract: If a relative rotational phase between a first rotor drivably connected to a crankshaft and a second rotor drivably connected to a camshaft is not an intermediate lock phase when an engine is started, a fuel injection starting timing is delayed more than that of the time when the relative rotational phase is the intermediate lock phase. The delay time is determined according to the working oil temperature of a valve timing mechanism during the engine start or the same oil temperature at the previous stop time of the engine, for example. As a result, the start of the engine can be completed as soon as possible while retaining the startability of the internal combustion engine.

Abstract: A controller for a variable valve device of an internal combustion engine includes a hydraulic valve timing changing mechanism that changes the valve timing VT of an intake valve, a valve timing locking mechanism that locks the valve timing VT to an intermediate phase, and an electronic controller that controls the operation of the valve timing changing mechanism.

Abstract: In a variable valve timing control apparatus, a hydraulic variable valve timing device adjusts valve timing by changing a VCT phase. In a lock mode, the lock pin is allowed to be displaced in a lock direction for locking the VCT phase, and the VCT phase is slightly shifted in a lock-mode VCT phase shift direction corresponding to one of an advance direction and a retard direction. A lock control unit shifts the VCT phase in a direction opposite from the VCT phase shift direction if the VCT phase is located on a lock-mode VCT phase shift direction side of the intermediate lock position when the engine becomes equal to or less than a first rotational speed, and otherwise the lock control unit allows the lock pin to be displaced in the lock direction.
