Abstract

Provided is a mechanical force-balancing device, pertaining to the technical field of internal combustion engines. The mechanical force-balancing device comprises a lower segment of an intake valve, a middle segment of the intake valve, an upper segment of the intake valve, a control body, a fixing plate, an elastic part, a rotary plate, a rotary shaft and connecting pipes. The middle segment of the intake valve penetrates through the rotary shaft, the interior of which is provided with four cavities. The middle segment of the intake valve is provided with four ribbed bars which are respectively arranged in the four cavities of the rotary shaft. One end of a first connecting pipe is communicated with a right-side cavity of the control body. The other end of the first connecting pipe is communicated with an engine exhaust pipe. One end of a second connecting pipe is communicated with a left-side cavity of the control body. The other end of the second connecting pipe is communicated with a turbine exhaust pipe. In the mechanical force-balancing device, the middle segment of the intake valve rotates clockwise at high internal pressure of the control body so that the valve lift and air inflow of an engine increase. The mechanical force-balancing device is reasonable in design and simple in structure and is suitable for design of a continuous variable system of the lift of the intake valve.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a mechanical force balance device which can realize continuously variable intake valve lift on the principle of aerodynamics. 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...
