Should the damper of a gasoline engine be open or closed?

Gasoline engine. The damper is open when working.

The function of the damper is to change the amount of air entering the inlet of the carburetor, change the oil pressure of the fuel injector, and change the concentration of the mixture.

Starting the engine in winter feels difficult.

Gasoline engine] Gasoline engine generally adopts a reciprocating piston structure, which consists of a body and a crank connecting rod mechanism.

It is composed of gas distribution system, oil supply system, lubrication system and ignition system.

Advantages] The gasoline engine is lighter than the diesel engine, the manufacturing cost is low, the noise is smaller, the low temperature starting performance is better, but the thermal efficiency.

Low and high fuel consumption rate. Motorcycles, chain saws and other low-power power machinery, in order to be light and cheap, commonly used two-stroke air-cooled gasoline engines; In order to have a simple structure, reliable operation and low cost, most of the stationary low-power gasoline engines use four-stroke water-cooled type; Cars and light trucks mostly use overhead valve water-cooled gasoline engines, but with the increasing attention to fuel consumption, diesel engines are increasingly used in such vehicles; In order to be light and have a high liter power, most of the engines used in small aircraft use air-cooled gasoline engines with hemispherical combustion chambers.

Difference from diesel engine].

After the gasoline engine is ignited, the gas mixture in the gasoline engine burns instantaneously and bursts out of energy, so the cycle can be repeated many times per unit time, and high power is output at high speed, so the small volume and light weight can have higher performance and faster response speed, and the wide speed range can also bring a better handling feeling. After the diesel engine is injected with fuel, it takes a certain amount of time to burn, so it is suitable to let the fuel fully burn at a lower speed to bring high torque, and in order to resist the high pressure and high torque in the cylinder, the cylinder and piston connecting rod and other parts of the diesel engine are stronger than the gasoline engine, so they are more bulky than the gasoline engine.

The damper must be opened!

I don't know who told you that the damper costs nothing after opening?? This statement is completely false.

The damper must be wide open! Only when the weather is cold and the start is slightly turned off.

The principle is that a large amount of fresh air enters the carburetor and mixes with gasoline to form a certain proportion of mixture, and then after entering the cylinder body and being compressed by the piston, there is a spark plug to detonate the mixture, and the detonated mixture generates huge energy and then pushes the piston to work continuously. When the damper is closed, a lot of air doesn't get in, and no huge amount of energy is generated. Closing the damper is only aimed at preventing a large amount of cold air from entering when the cold engine is started, and it is easy to start the machine with a small amount of air entering.

After the machine starts, the damper must be opened to let the machine work continuously with high power.

It's closed. 1: Strictly speaking, it is open for fuel economy, and the small store inside is open. But what people usually call an open damper is actually closed on the inside.

2: This engine is designed to take into account that gasoline is not easy to evaporate in winter, and it is difficult to start, so a choke door is specially designed to increase the concentration of mixture. This makes it easier to start.

2: The function of the gasoline engine damperThe function of the damper is to change the amount of air entering the inlet of the carburetor, change the oil pressure of the fuel injector, change the concentration of the mixture, and it is very difficult to start the engine in winter. Especially when I start the car in the morning, I am even more overwhelmed.

3: It is difficult to start in winter, because the weather is too cold, and the engine needs to be warmed up.

When the generator cold engine starts, the choke should be closed first, and the damper should be opened after starting, and then loaded. If it is a hot engine (for example, it has been running for a long time, and then turned on again after shutting down halfway), then start directly with the damper open. In order to improve the concentration of the mixture, the choke door must be closed to reduce the air intake and facilitate the start.

In order to drive the load normally, it must be in an open state, otherwise the air intake is not enough, the concentration of the mixture is too high, the combustion is not complete, and the power does not swim away.

The gasoline engine is always open when it works. The function of the gasoline engine damper: the function of the damper is to change the amount of air entering the inlet of the carburetor, change the oil pressure of the fuel injector, and change the concentration of the mixture.

Starting the engine in winter feels difficult. Especially when I start the car in the morning, I am even more overwhelmed. In fact, it is difficult to start in winter, mainly in carburetor engines.

This kind of engine boring motive is designed to take into account that gasoline is not easy to evaporate in winter, and it is difficult to start, so the choke door is specially designed. The function of the air blocking and air monitoring door is to reduce the amount of air entering the inlet of the carburetor, increase the oil pressure of the fuel injector, and increase the concentration of the mixture. This makes it easier to start.

The gasoline engine is always open when it works.

The choke is a component on the carburetor of a gasoline engine, which is generally operated at the intake of the carburetor through a control knob mounted on the instrument panel. Its function is to properly close part of the air intake when the engine is cold started, increase the gasoline concentration of the mixture entering the cylinder, improve the starting performance of the engine, after the normal operation of the engine should be completely beaten open the choke door, otherwise it will be because the mixture is too concentrated to cause the orange cleaning machine can not operate normally and cause excessive oil consumption, the EFI engine is automatic control does not need manual operation.

The function of the gasoline engine damper is to change the amount of air entering the inlet of the vaporizer, change the oil pressure of the fuel injector, and change the concentration of the mixture.

Summary. Hello dear! This kind of failure generally occurs when the generator has been put out of use for a long time, and this situation often occurs when it is used again, and the fault point is caused by the blockage of the carburetor.

Gasoline power generation is good for ignition, what is the problem of turning off the damper as soon as it is opened?

Hello dear! This kind of failure generally occurs when the generator has been put out of use for a long time, and this situation often occurs when it is used again, and the fault point is caused by the blockage of the carburetor.

Pro: The generator can be started, which means that there is no problem on the circuit. If there is no problem in the circuit, it can only be a fault in the oil circuit. Since it can be started, it means that the fuel tank is supplied smoothly, and all that remains is the carburetor.

It may be that there is a problem with the debugging carburetor, and the ratio of oil and air is seriously unbalanced: there is more air and less oil, which causes the flame to fail to erupt. It is recommended to replace or adjust the carburetor.

The function of the damper is to adjust the air ratio of the combustion chamber, specifically to reduce the incoming air, and at the same time increase the concentration of gasoline in the combustion chamber, so as to facilitate the start of electronic ignition. You lower the air content at once, increase the concentration of gasoline, and it can't burn (there is no oxygen). The damper is used when it is cold in winter, and now it is generally not needed, and opening the damper is in principle to close the intake valve.

When you open the damper, the mixer will be too thin, not easy to ignite, and it will not be easy to start, and the car will run at a speed after starting.
