The invention discloses an oil passage structure of a variable valve lift mechanism, which includes a cylinder head oil passage, a rocker shaft oil passage and a rocker arm oil passage, and also includes a control valve oil passage and a valve core. The oil passage of the rocker shaft is connected, the oil passage of the rocker shaft is connected with the oil passage of the rocker arm, and the oil passage of the control valve and the oil passage of the cylinder head are arranged side by side. The spool is arranged in the oil passage of the control valve and can move correspondingly to the oil passage of the drain chamber and the oil inlet passage of the cylinder head, and the oil passage of the control valve is provided with an oil inlet passage of the control valve. Controlled by a solenoid valve, the structure of the oil circuit is simple, the processing and assembly are simple, the process is relatively simple, and the cost is low.
Description
technical field [0001] The invention relates to the technical field of an engine valve mechanism, in particular to an oil circuit structure of a variable valve lift mechanism. Background technique [0002] The gas distribution mechanism is one of the two key mechanisms on the engine. The gas distribution mechanism is the control mechanism for the intake and exhaust. Supply combustible mixture (port injection gasoline engine) or fresh air (diesel engine) and discharge exhaust gas in time to meet the intake and exhaust requirements of the engine, and meet the performance requirements of the engine through reasonable intake and exhaust timing design. When the intake and exhaust valves are closed, the cylinder is guaranteed to be sealed. The valve mechanism has many moving parts and is affected by many other factors. The stress of each part during the movement is relatively complicated, and the precision and strength of each part are required to be high. Reliability matters a ...
