Abstract

An inflation efficiency adjusting system belongs to the technical field of an internal combustion engine. The inflation efficiency adjusting system comprises an engine air inlet pipe, an engine, an engine air exhausting pipe, a connection pipe, an adjusting cavity, a movable plate and a spring, wherein the movable plate is arranged in an adjusting cavity and is in sealed contact with an inner wall surface of the adjusting cavity; the movable plate is connected with a right wall surface of the adjusting cavity by the spring; one end of a second connection pipe is communicated with a left wall surface of the adjusting cavity and the other end of the second connection pipe is communicated with the engine air exhausting pipe between a catalyzing bag and a silencer. According to the inflation efficiency adjusting system, when the engine is operated at a low speed working station, the capacity of an air pipe is larger; when the engine is operated at a high speed working station, the capacity of the air pipe is smaller, so that the capacity of the air inlet pipe can be automatically adjusted. The inflation efficiency adjusting system is reasonable in design and simple in structure, and is suitable for an optimized design of an air inlet system of a natural air suction internal combustion engine.

Description

technical field [0001] The invention belongs to the technical field of internal combustion engines, and specifically relates to an inflation efficiency adjustment system capable of realizing 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 the pressur...
