Abstract

The invention discloses a continuous variable system for an engine intake valve. The continuous variable system comprises the intake valve, an intake valve oil cavity and a boosting oil cylinder, wherein a piston is installed in the intake valve oil cavity; the end face of the piston is connected with one end of a connecting rod, and a connecting assembly is installed between the other end of theconnecting rod and the intake valve; the intake valve is in transmission connection with an engine cam; the boosting oil cylinder is connected with the intake valve oil cavity through an oil inlet pipe; an oil discharge outlet is further formed in the intake valve oil cavity; and an oil drainage cavity is formed in one side of the intake valve oil cavity. The continuous variable system is simple in working principle and high in control efficiency, the robustness and reliability of the system are guaranteed, cost and energy consumption are reduced, and continuous adjustment of closing timing ofthe multi-cylinder intake valve can be achieved.

Description

technical field [0001] The invention relates to the technical field of variable intake valves, in particular to an engine intake valve continuously variable system. Background technique [0002] The traditional four-stroke engine generally uses a mechanical cam to drive the valve train of the intake valve and the exhaust valve. The valve movement is controlled by the mechanical transmission between the cam and each valve. This mechanical mechanism is simple and reliable, but the parameters such as the opening time and phase of the valve mechanism are fixed, and the performance of the engine cannot be fully utilized. The variable gas distribution technology can make the valve timing provide variable valve opening and closing time or lift under different engine speeds and loads, thereby improving engine intake and exhaust performance, and better meeting the needs of the engine at high speeds and loads. Due to the power, economy and emission requirements at low speed, high loa...
