Problems solved by technology

[0005] 1. The structure of the existing air intake system is designed on the side of the engine cylinder, so that the size of the side of the engine is too large, which has limitations in the design of the product;
[0006] 2. The length of the intake pipe is too short, and the carburetor is too close to the engine cylinder. The heat generated by the engine cylinder will cause the temperature of the gasoline mixture to change, resulting in excessive gasoline temperature and a distillation range. This reaction will reduce the fuel consumption of the engine. , power, and speed will be affected to varying degrees;
[0007] 3. Because the intake pipe is too short and the carburetor is too close to the engine cylinder, the filter cotton cannot effectively relieve the gasoline mixture when it recoils, causing the filter cotton to absorb gasoline, causing the Unstable factors such as failure of the oil filter and air filter;
[0008] 4. The structure of the existing air intake system has only one connection and fixed point design. The vibration generated during the operation of the engine will cause the components of the air intake system to loosen, crack, fall off and other undesirable phenomena

Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing.

[0019] The air intake system of the small gasoline engine of the present invention is one of the main mechanisms of the small gasoline engine. Air cleaner 6, negative pressure pipe 7 etc. are formed.

[0020] The intake pipe 2 is provided with an intake pipe flange 1, the intake pipe flange 1 is fixedly connected with the engine cylinder air inlet, the other end of the intake pipe 2 is connected with the carburetor 4, and the carburetor 4 is connected by the carburetor bracket 5 and the The gear box is fixedly connected, and the air filter 6 and the carburetor 4 are arranged side by side and away from the engine cylinder 8 .

[0021] An air storage bag 3 is provided in the middle of the intake pipe 2, and a negative pressure pipe 7 is provided between the intake pipe flange 1 and the carburetor bracket 5.

[0022] The air intake system of the small gasoline engine of the ...

Abstract

The invention provides an air inlet system of small gasoline engine classes. The air inlet system is composed of an inlet pipe flange, an inlet pipe, an air storage bag, a carburetor, a carburetor support, an air filter and a negative pressure pipe. The air inlet pipe flange is arranged on the air inlet pipe and is fixedly connected with an air inlet of an engine cylinder, the other end of the air inlet pipe is connected with the carburetor which is fixedly connected with a gearbox through the carburetor support, and the air filter and the carburetor are arranged side by side and is away from the engine cylinder. The air inlet system has the advantages that since the length dimension of the air inlet pipe is increased and the mounting position and direction of the air filter and the carburetor are changed, the air filter and the carburetor are away from the engine cylinder, heat of air inflow to power is reduced, the temperature of gasoline is always controlled within a distillation range point, fuel consumption, power and rotation speed of the engine can be effectively regulated and controlled, and the like.

Description

technical field [0001] The invention belongs to the technical field of intake systems, in particular to a small gasoline engine intake system. Background technique [0002] The intake system is one of the main mechanisms in a small gasoline engine. The principle of power work is divided into two strokes and four actions: 1. intake, compression, 2. combustion expansion, and exhaust. Air and gasoline are mixed in a certain proportion to form a good mixture, which is sucked into the cylinder during the intake stroke. The mixture is compressed and ignited to generate heat energy. The high-temperature and high-pressure gas acts on the top of the piston to explode and burn instantly, thereby pushing the piston to move. Among them, the intake system is an important fuel transmission mechanism, the purpose is to effectively input the fuel mixed with air into the cylinder for reaction, so the intake system has a great influence on the working efficiency of the power. The role of the...
