CN201277115Y - Air-intake diaphragm controlled economizer - Google Patents

Abstract

The utility model relates to an intake diaphragm control fuel economizer, which is characterized in that a connecting tube of an engine and a connecting tube of a carburetor are symmetrically and evenly arranged on the two sides of a joint, a unidirectional diaphragm is clung on the connecting tube of the carburetor, and the unidirectional diaphragm is fixed on the connecting tube end of the carburetor in the inner side of the joint by a fastening nail. When the engine is compressed, the throat vacuum degree of the intake diaphragm control fuel economizer disappears, the unidirectional diaphragm resets to form a sealed carburetor which can prevent compressed gas from back-spraying, thereby achieving the functions of the unidirectional control of an air inlet throat tube, increasing the service efficiency of fuel oil, and saving the fuel oil.

Description

Intake Diaphragm Control Fuel Economizer

technical field

The utility model relates to an air intake system of a motor vehicle, in particular to an air intake diaphragm control fuel economizer.

technical background

At present, four-stroke motorcycles generally use reciprocating engines to account for the vast majority. This mechanism is simple in structure and easy to maintain, but there are obvious shortcomings: because the valve mechanism of reciprocating engines usually adopts reset valves, it is difficult to drive for a while. After a period of time, the intake valve wears and leaks due to lack of lubrication, which causes gasoline to be sprayed back when the engine is compressed, resulting in excessive fuel consumption and unsmooth engine operation.

Utility model content

The purpose of the utility model is to provide an air intake diaphragm control fuel economizer, so that on the basis of ensuring the simple structure of the original intake system and convenient maintenance, it also has the functions of reducing fuel consumption and prolonging the service life of the engine, which can be used as a four-stroke motorcycle. The intake diaphragm of the car intake system controls the fuel economizer.

The utility model is realized by the following technical scheme: the air intake diaphragm control fuel economizer is mainly composed of an engine connecting pipe, a joint, a one-way diaphragm, a fixing nail, and a carburetor connecting pipe. First, connect the engine connecting pipe with the intake pipe of the engine, the carburetor connecting pipe and the carburetor, the fixing nails play the role of fixing the one-way diaphragm, and the joint is formed with the engine connecting pipe and the carburetor connecting pipe One-piece, under the suction of the engine, the one-way diaphragm is opened to form an air intake. When the engine is compressed, the throat vacuum disappears, and the one-way diaphragm resets to form a seal to prevent the compressed gas from spraying back into the carburetor, realizing the air intake throat. One-way control, so as to improve fuel efficiency and save fuel.

Compared with the prior art, the use of the air intake diaphragm to control the fuel economizer can solve the disadvantages of high fuel consumption, insufficient power and the like caused by air intake reverse injection.

To sum up, just because the air intake diaphragm control fuel economizer has the function of solving the problems of high fuel consumption, insufficient power and unsmooth operation of the engine caused by the intake reverse injection, thereby prolonging the service life of the engine and saving fuel.
