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. | 02-20-2014 |
20140069359 | VARIABLE VALVE TIMING DEVICE - A variable valve timing device that allows a valve timing of an engine valve to be varied by relatively rotating a vane rotor and a housing. The variable valve timing includes a lock mechanism that releases the locking in accordance with the application of a lock releasing oil pressure. A crank angle CCA at which the application of the lock releasing oil pressure is instructed can be varied in accordance with an engine speed NE so that the lock releasing oil pressure rises at a crank angle in which cam torque is suitable for lock releasing. | 03-13-2014 |
20140069363 | VARIABLE VALVE TIMING DEVICE - In a variable valve timing device, which varies the rotational phase of a camshaft through the relative rotation of a vane rotor and a housing and is provided with a lock mechanism that releases the lock thereof in response to the application of lock-release hydraulic pressure, the crank angle CCA at which the application of lock-release hydraulic pressure is commanded is set variably in accordance with the pressure of the oil supplied for the application so that the lock-release hydraulic pressure rises at a crank angle at which the state of the cam torque becomes suitable for lock-release without relying on changes of time needed for the lock-release hydraulic pressure to raise resulting from oil temperature. | 03-13-2014 |
20150285105 | OIL CONTROL VALVE - 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. | 10-08-2015 |
