The invention belongs to the technical field of machine design and relates to a double-fan-engine air inlet adjusting device. The device comprises a first adjusting body, a rotary shaft, a rotary body, a stretching body, centrifugal bodies, balls, pull rods, movable bodies and springs. The adjusting body is arranged on the front portion of an exhaust manifold; the rotary shaft and the rotary body are fixedly connected together; the stretching body and the centrifugal bodies are all arranged in the rotary body, and the balls are embedded in the stretching body; one side walls of the centrifugal bodies make contact with the stretching body through the balls, and the other side walls of the centrifugal bodies are connected with the inner wall face of the rotary body through the first springs; the top of the stretching body is connected with the inner wall face of the rotary body through the second spring; and the rotary shaft is connected with a crankshaft of an engine through a chain. When the rotation speed of the engine is high, adjusting plates rotate anticlockwise, and the volume of an air inlet pipeline is decreased; and when the rotation speed of the engine is low, the adjusting plates rotate clockwise, and the volume of the air inlet pipeline is increased. The device is reasonable in design, simple in structure and suitable for optimal design of variable air inlet pipe systems.
Description
technical field [0001] The invention relates to a double-sector engine air intake regulating device in the technical field of mechanical design, in particular to a double-sector engine air intake regulating device suitable for an air intake pipeline volume variable system. Background technique [0002] Present engines can be divided into naturally aspirated and supercharged, and supercharged can be divided into mechanical supercharging, turbocharging and the latest air wave supercharging. The naturally aspirated type does not have a supercharger, which means that the air simply passes through the air filter, throttle valve, and intake manifold to reach the cylinder, and gasoline is directly injected into the intake manifold through the fuel injector. Taking a four-cylinder engine as an example, a piston has four strokes for one work: down (the intake valve opens, there is a pressure difference, and the mixture of air and fuel enters the cylinder under the action of the press...
