Abstract

The invention belongs to the technical field of mechanical design and relates to a mechanical multidirectional movement mechanism comprising an intake valve, control cavities, a rotating shaft, a rotating rod, a stretching rod, springs, a moving body, moving plates and connecting pipes. Four cavities are arranged inside the rotating shaft, four ribs are arranged in the middle section of the intake valve, slope structures of the moving body, the first moving plate and the second moving plate are matched with one another, one end of the rotating rod is hinged to one end of the stretching rod, one end of the first connecting pipe is communicated with a lower cavity of the second control cavity, the other end of the first connecting pipe is communicated with an engine intake pipe, one end of the second connecting pipe is communicated with an upper cavity of the second control cavity, and the other end of the second connecting pipe is communicated with an turbine exhaust pipe. When pressure in the control cavities is high, the middle section of the intake valve rotates clockwise, valve lift is increased, and engine air intake is increased. The mechanism is rational in design, simple in structure and applicable to design of continuously variable intake valve lift systems.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and specifically relates to a mechanical multi-directional motion mechanism capable of realizing continuously variable lift of an intake valve on the principle of pneumatics. 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 area...
