Abstract

The invention provides an engine gas distribution mechanism applied in the technical field of automobile engines. The engine gas distribution mechanism includes a valve (1), a hydraulic tappet (2), a roller rocker arm (3), and a camshaft (4) , the camshaft (4) is in contact with the roller rocker arm (3), the two ends of the roller rocker arm (3) are respectively in contact with the valve (1) and the hydraulic tappet (2), and the end of the camshaft (4) Connect with the drive motor (5), and the slot (6) on the drive motor (5) is connected with the engine wire harness (9). The engine valve mechanism of the present invention has a simple structure, can ensure faster response speed and more precise control, can save the conventional engine timing belt or chain drive mechanism, and can also solve the timing disorder and timing difference of the cold start of the engine in winter It is also easy to implement the variable valve timing function to prevent rattling and other timing system problems.

Description

technical field [0001] The invention belongs to the technical field of automobile engines, and more specifically relates to an engine valve 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. Combustible gas mixture (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 lot. At present, the conventional valve me...
