Abstract

The invention discloses a valve adjusting mechanism with a groove structure, and belongs to technical field of mechanical design. The valve adjusting mechanism comprises an inlet valve, an exhaust valve, a compressor, a turbine, a lever, a tappet, a volume cavity, a moving body, a fulcrum bar and a connecting pipe, wherein the moving body is mounted in the volume cavity and is in contact with the inner wall surface of the volume cavity hermetically; a round hole is formed in the upper wall surface of the volume cavity; the lower end of the fulcrum bar passes through the round hole in the upper wall surface of the volume cavity and then is in contact with the inclined plane of a triangular groove; and the upper end of the fulcrum bar is in contact with the lever. When the pressure in an air inlet pipe of an engine is higher, the fulcrum bar is moved downwards, and the inlet valve lift becomes high; and when the pressure in the air inlet pipe of the engine is lower, the fulcrum bar is moved upwards, the inlet valve lift becomes low. The valve adjusting mechanism is reasonable in design, simple in structure, and suitable for engine valve stroke variable system.

Description

technical field [0001] The invention relates to a mechanically designed engine intake valve lift adjustment system, in particular to a valve adjustment mechanism with a groove structure. Background technique [0002] The valve lift of the traditional gasoline engine is fixed and invariable, that is, there is only one cam profile of the camshaft, which makes it impossible for the lift to make the engine respond well in both high-speed and low-speed areas. The valve lift or cam profile design of a traditional gasoline engine is a balanced choice for the engine under all operating conditions. As a result, the engine can neither get the best high-speed efficiency nor the best low-speed torque, but it can get The most balanced performance under all working conditions. The adoption of variable valve lift enables the engine to obtain the required valve lift in both high-speed and low-speed areas, thereby improving the high-speed power and low-speed torque of the engine.
