摘要： A variable valve timing apparatus includes: a variable valve timing mechanism; an intermediate locking mechanism that locks the valve timing at an intermediate timing; and a hydraulic pressure supply device that hydraulically actuates these mechanisms. The hydraulic pressure supply device uses a single oil control valve to control a state where lubricating oil is supplied to or drained from each of an advance chamber, a retard chamber and an intermediate chamber of an intermediate locking mechanism. The oil control valve has first to fourth modes. The oil control valve advances the valve timing and actuates the intermediate locking mechanism in a projecting direction in the third mode, and, under a situation that the amount of lubricating oil supplied to the variable valve timing mechanism is smaller than that in the third mode, advances the valve timing and actuates the intermediate locking mechanism in a release direction in the fourth mode.

摘要： In a hydraulic variable valve timing mechanism including a lock pin that locks a vane rotor and a housing against relative rotation in the most retarding phase, a specified angle α is set so that release of the lock pin is started at a time when positive cam torque acts on the vane rotor. When the crank angle reaches the specified angle α, supply of hydraulic pressure to the advancing oil chamber is started to release the lock pin from the engagement with the lock hole, thereby enabling a reliable release of the lock pin prior to start of change of valve timing.

摘要： A variable valve actuation device for an internal combustion engine includes a variable valve timing mechanism and a valve timing restricting mechanism. When the operating state of the variable valve timing mechanism is in the phase restricting state and the operating state of the variable valve timing mechanism is changed to the phase releasing state on the basis of pressing the accelerator pedal, a torque limiting control is then performed to limit an increase in the torque of the internal combustion engine. With this control the rate of increase of the torque is set less than the rate of increase of the torque corresponding to the operation of pressing the accelerator pedal by retarding and correcting the ignition timing. Thus, when the operating state of the variable valve timing mechanism is changed from the phase restricting state to the phase releasing state, thereby reducing discomfort experienced by the driver.

摘要： An oil control valve has a housing and a spool valve that is arranged in the housing and is movable in the axial direction. The movement range of the spool valve includes a first area and a second area. In the first area, a port that is connected to a lock mechanism opens to prevent the movement of a variable valve timing mechanism through drainage of oil from the lock mechanism. In the second area, oil is supplied and drained to and from the variable valve timing mechanism through a passage inside the spool valve. The first area exists at a position separated from the second area in the movement range.

摘要： A primary resilient member urges a primary limiting member into a recess in an inserting direction in a state where a rotational phase is a limited phase in a limited phase range. A relative slide gap is radially provided between the primary limiting member and a secondary limiting member at a location adjacent to a working chamber. First and second primary slide gaps are radially provided between the primary limiting member and radially opposed wall surface sections of the receiving hole. A secondary slide gap is radially provided between the secondary limiting member and a radially opposed wall surface section of the receiving hole. The relative slide gap is larger than the first and second primary slide gaps and the secondary slide gap.

摘要： 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.

摘要： A start control device for an internal combustion engine controls a starting manner of the engine having a hydraulic variable mechanism, which fixes valve timing at a middle angle. Specifically, with the engine speed during cranking when the valve timing is not fixed at the middle angle defined as a first engine speed and the engine speed during cranking when the valve timing is fixed at the middle angle defined as a second engine speed, the start control device performs starting control for decreasing the first engine speed compared to the second engine speed during engine starting. As a result, the valve timing is fixed at the middle angle at increased frequency.
