摘要： PROBLEM TO BE SOLVED: To restrain the deterioration in a combustion state by the performance of cylinder resting operation, by improving fuel economy by performing the cylinder resting operation in the widest engine operation area, regardless of whether a variable valve train is an operation permitting state or an operation prohibiting state.
SOLUTION: An engine operation area for performing the cylinder resting operation in cylinder resting control is switched between a cylinder resting area AP1 and a cylinder resting area AP2, in response to the fact of whether valve timing control of an intake valve 9 is performed in the operation permitting state of the variable valve train 13 or the valve timing control is stopped in the operation prohibiting state of the mechanism 13. Therefore, the engine operation area for performing the cylinder resting operation can be set in an area suitable to respective states in response to the fact of whether the variable valve train 13 is the operation permitting state or the operation prohibiting state.

摘要： PROBLEM TO BE SOLVED: To achieve both of excellent starting characteristics and stability in idling operation in an engine equipped with a variable valve timing mechanism for adjusting the opening/closing timing of an intake valve. SOLUTION: This variable valve timing control device is provided with a torsion coil spring (an advance energizing spring) 110 advancing the rotation phase of an intake camshaft 12 against the cam torque of the intake camshaft 21, and a motor-driven oil pump (a sub-oil pump) 20 assisting oil pressure supplied to the variable valve timing mechanism 100. When starting the engine 1, the opening/closing timing of the intake valve 13 is held into a predetermined advance position by the energizing force of the torsion coil spring 110. An actual compression ratio in starting is thereby improved to secure excellent starting characteristics. During idling operation after the start of the engine, the motor-driven oil pump 20 is driven to delay the opening/closing timing of the intake valve 13 with respect to the starting advance position. Valve overlap is thereby reduced to secure stable idling operation. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of detecting variation of actual rotation phase of a camshaft accompanying opening and closing of an engine valve in relation to theoretical rotation phase and taking a suitable countermeasure for increase of the variation. SOLUTION: Variation of actual rotation phase in relation to the theoretical rotation phase at a time when the camshafts 14, 15 are rotated at constant speed with an average rotation speed occurs in the camshafts 14, 15 at a time of opening and closing of valves. Elapsed time from a reference timing to a timing when a predetermined part of the camshafts 14, 15 in a circumference direction abuts on valve lifter 12a, 13a is measured. The theoretical rotation phase is calculated from the elapsed time of each part where the variation is not significant, elapsed time (theoretical value) with the theoretical rotation phase of the elapsed time mentioned above of a part where the variation is significant is, thereby estimated. Difference between an actually measured value of the elapsed time and the theoretical value of a part where the variation is significant is detected as the variation. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a variable valve mechanism for the interval combustion engine in which an actuator of which the valve characteristics of an intake and exhaust valve of the internal combustion engine is variable can comply with a wide range of the operation state of the internal combustion engine. SOLUTION: For operating an intake cam shaft 45 in the axial direction, an oil pressure type lift quantity variable actuator 101 and an electric type lift quantity variable actuator 102 are provided. Thus, the intake cam shaft 45 can be driven in the axial direction by means of the electric type lift quantity variable actuator 102 in the case the oil pressure type lift quantity variable actuator 101 is improper due to an oil pressure shortage. The intake cam shaft 45 can be driven in the axial direction with the oil pressure type lift quantity variable actuator 101 by stopping power supply to the electric type lift quantity variable actuator 102 in such a state that the oil pressure is sufficient and the fuel cost deteriorates when using an electric energy. In this way, the variable valve mechanism can comply with a wide range of the engine operation state.
