Abstract

The invention belongs to the technical field of internal combustion engines, and discloses a rotary plate and fixed plate matching device. The rotary plate and fixed plate matching device comprises air inlet pipes of an engine, the engine, exhaust pipes of the engine, connecting pipes, adjusting cavities, movable plates, a spring, fixed plates and a rotary shaft. The first adjusting cavity and the second adjusting cavity are coaxially connected with each other by the rotary shaft, the spring is arranged on an anticlockwise rotation side of the second rotary plate and is connected with the second rotary plate and the second fixed plate, one end of the second connecting pipe is communicated with the second adjusting cavity, the other end of the second connecting pipe is communicated with the certain exhaust pipe of the engine, and the certain exhaust pipe of the engine is positioned at the front of a catalysis pack. The rotary plate and fixed plate matching device has the advantages that the air inlet pipes are large in volume when the engine runs under low-speed working conditions and are low in volume when the engine runs under high-speed working conditions, and accordingly the volumes of the air inlet pipes can be automatically adjusted; the rotary plate and fixed plate matching device is reasonable in design, simple in structure and applicable to optimally designing air inlet systems of naturally aspirated internal combustion engines.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and in particular relates to a rotating plate fixing plate matching device capable of realizing the self-adjustment of the volume of an intake pipe of a naturally aspirated engine. 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 th...
