The invention discloses a fully variable valve timing and lifting mechanism for a variable linear chute, which is one of reciprocating combustion engine valve control mechanisms. The disclosed technology at present has no the technique of capable of combining the lasting opening time of a variable valve with the lifting range of the valve together, and has more efficient action only when the lasting opening time of the valve and the lifting range of the valve are combined. With the adoption of the fully variable valve timing and lifting mechanism for the variable linear chute, an oscillating bar is driven to drive the valve to open through a sliding connection link; the sliding connection link is in longitudinal movement and lateral oscillation; the angle and position of a sliding chute are controlled by utilizing a control mechanism; and the ratio of the longitudinal movement and the lateral movement, and the position of a sliding middle point of a single shaft are controlled by controlling the single shaft at one end of the sliding connection link so as to independently control the lasting opening time of the valve and the lifting range of the valve. According to the fully variable valve timing and lifting mechanism for the variable linear chute, control of the combustion engine valve can be optimized, the pumping loss is reduced and the efficiency of the combustion engine is improved.
