摘要： PROBLEM TO BE SOLVED: To provide a variable valve system for an internal combustion engine whose valve action angle, valve lift, and valve timing are continuously variable, in which degradation of starting performance is suppressed and a continued operation of the internal combustion engine is ensured even at an anomaly of the system. SOLUTION: Since oil pressure is dissipated at a start-up or at an anomaly of the system, the urging force of a spring 144 can press a pin 148a against a guide portion 130. The guide portion 130 can in turn set a lift varying actuator 100 in a condition to create a valve action angle and a valve lift other than minimum values. The valve action angle and the valve lift by the intake cam 45a can be set at appropriate values to ensure a sufficient intake air quantity. By such a constitution, the degradation of starting performance can be suppressed and turnout travel is made possible. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To prevent increasing of a program development process and a memory capacity, and ensure engine startability and stability with refuge running capable, always by a fixed fail-safe process so as to be capable of coping with that even when a trouble is caused in a valve lift amount adjusting mechanism of an internal combustion engine. SOLUTION: A stable position of an intake can shaft is unified in a position as shown by a drawing (A) even in any trouble of an electric system and hydraulic system. Accordingly, a fixed fail-safe process can always cope with the trouble, increasing of a program development process and a memory capacity can be prevented. A condition that a valve lift amount of an intake valve is minimum further with closed timing Ci shifted to a side of advance angle is provided even at any trouble time, as shown in the drawing (A). In this way, the intake valve can be closed earlier, to enhance startability of an engine. Accordingly, refuge running can be made by early starting after a trouble.

摘要： PROBLEM TO BE SOLVED: To improve the durability of a valve lifter and a variable valve system for a three-dimensional cam by enhancing the degree of freedom for designing a detent mechanism of the valve lifter for the three-dimensional cam. SOLUTION: A thick wall part 19j is made up by an offset D1 lying between an outer circumferential surface 19a and an inner circumferential surface 19f of a valve lifter 19 and the other parts are formed into being thinned. Therefore the thick wall part 19j being sufficiently thickened is formable without increasing most of weight. Accordingly a sufficient sized projection 19b is attached to the valve lifter 19 without causing any distortion in the lifter 19, and thereby a contact area to a detent groove 9b is increased, making any surface pressure reducible, and thus durability is improvable in the way. Since the thick wall part 19j exists lengthily in the axial direction of the valve lifter 19, a detent mechanism is formable on the outer circumferential surface 19a of the valve lifter 19 even in case of being not in the vicinity of a top surface 19k. Consequently the degree of freedom for designing the detent mechanism is promoted.
