Fully variable valve timing and lifting mechanism for variable linear chute

Abstract

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.

Description

technical field [0001] The invention relates to a fully variable valve timing and lift mechanism of a variable linear chute, which refers to a mechanism for driving and controlling a reciprocating internal combustion engine valve. The lift and timing of the internal combustion engine valve driven by it can be controlled within a certain range. Do independent adjustments. Background technique [0002] The valve drive of the internal combustion engine adopts continuously variable valve timing, which can increase the filling rate of the cylinder of the internal combustion engine, improve power and efficiency, reduce the working temperature of the cylinder, and reduce the pollution emission of the internal combustion engine. The intake valve drive of the internal combustion engine adopts the continuously variable valve lift technology, which can improve the intake efficiency of the internal combustion engine, reduce fuel consumption, and improve the response speed of the interna...

Problems solved by technology

[0003] In the patent of publication number CN101149000A titled variable valve drive mechanism for internal combustion engines, the timing and lift of the valve are interrelated, that is, the duration of the valve opening is proportional to the lift of the valve opening, but the resulting The problem is that the advantages of the two adjustments of variable valve timing and variable valve lift cannot be well taken into account.
