Abstract

The invention discloses an air pressure difference value control type dislocation stress device, and belongs to the technical field of mechanical design. The device comprises an air inlet valve, control cavities, a rotating shaft, a rotating rod, a stretching rod, a spring, moving bodies and connecting pipes. Four cavities are formed in the rotating shaft, and four reinforced ribs are arranged on the middle segment of the air inlet valve; the four reinforced ribs on the middle segment of the air inlet valve are arranged in the four cavities of the rotating shaft; the lower wall face of the first moving body and the upper wall face of the second moving body are both provided with slope structures; one end of the first connecting is communicated with an upper cavity body of t he second control cavity, and the other end of the first connecting pipe is communicated with an exhaust pipe of an engine; and one end of the second connecting pipe is communicated with the upper cavity body of the second control cavity, and the other end of the second connecting pipe is communicated with a turbine exhaust pipe. According to the stress device, when the pressure in the control cavities is too high, the middle segment of the air inlet valve are rotated clockwise, the lifting range of the valve is increased, and the air inlet amount of the engine becomes large. The air pressure difference value control type dislocation stress device is reasonable in design, simple in structure and applicable to the design of an air inlet valve lift range variable system.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and specifically relates to an air pressure difference control type dislocation force bearing 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 ...
