摘要： PROBLEM TO BE SOLVED: To miniaturize a variable valve gear while maintaining a valve closed condition in the minimum lift condition and improving fuel economy performance effectively. SOLUTION: When a cam shaft 13 rotates in synchronization with a crank shaft, an oscillating cam 20 oscillates through an eccentric cam 15, a link arm 25, a rocker arm 18, and a link member 26 to open, close, and operate an intake valve 12. When a control shaft 16 rotates, a turning position of the oscillating cam 20 is relatively changed through the rocker arm 18 and cam lift characteristic is changed. A predetermined valve clearance is set between the oscillating cam 20 and the intake valve 12 in a base circle section θ1. In the minimum lift condition in which amount of cam lift of the oscillating cam 20 becomes the minimum, the maximum amount of cam lift of the oscillating cam 20 is set to be larger than 0 and smaller than the valve clearance.

摘要： PROBLEM TO BE SOLVED: To surely prevent interference of an intake valve and a piston in a control failure.
SOLUTION: When an operation angle control shaft 12 is rotated, an operation angle change mechanism 10 operates and an operation angle of the intake valve 1 is changed. When a phase control slider 43 is slid, a phase change mechanism 20 operates and a center phase of operation angle of the intake valve 1 is changed. When the operation angle is large, a slide range of a stopper 41 forming a part of the phase control slider 43 is limited by an arm 42 fixed or integrally formed on the operation angle control shaft 12, and advancement of the center phase is regulated. When the degree of advancement of the center phase is large, a rotation range of the arm 42 is limited by the stopper 41, and expansion of the operation angle is regulated.

摘要： PROBLEM TO BE SOLVED: To provide a variable valve gear for compatibly attaining reduced vibration due to decompression effects in an early cranking step at starting an engine and an increased cranking speed due to the decompression effects and the effect of reducing the friction of a valve system. SOLUTION: In Step 1, the engine is discriminated to be just before completely stopped or not. In Step 2, a closing timing for an intake valve is controlled to be before a bottom dead center but sufficiently near a top dead center by a lift varying mechanism and a valve timing varying mechanism, when it is discriminated to be just before stopped. In Step 5, an ignition switch is discriminated to be on and then a decompressed condition is established and the friction of the valve system are reduced in first one cranking to reduce engine vibration and improve startability. In Step 8, the closing timing for the intake valve is quickly controlled to be retarded by both varying mechanisms to actualize good combustion and quick complete explosion with an improved effective compression ratio.
