Mechanical double plate rotation device

Abstract

The invention belongs to the technical field of internal combustion engines and provides a mechanical double-plate rotation device. The mechanical double-plate rotation device comprises an engine intake pipe, an engine, an engine exhaust pipe, connecting pipes, adjusting cavities, a moving plate, a spring, a fixing plate, a rotary shaft and a control valve, wherein the first adjusting cavity and the second adjusting cavity are coaxially connected through the rotary shaft, the spring is arranged on the clockwise rotation side of a second rotating plate and connected with the second rotating plate and a second fixing 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 exhaust pipe of an engine in front of a catalysis bag, and the control valve is arranged on the first connecting pipe. In the mechanical double-plate rotation device, the volume of the intake pipe is smaller when the engine operates under the low-speed working condition, the volume of the intake pipe is smaller when the engine operates under the high-speed working condition, and the volume of the intake pipe can be automatically adjusted. The mechanical double-plate rotation device is reasonable in design, simple in structure and suitable for optimization design of a natural air suction internal combustion engine intake system.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and specifically relates to a mechanical double-plate rotating device capable of self-adjusting 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 the pressure difference),...
