There is no pressure relief valve in the car, and I did not expect so many hazards

Today we talk about the pressure relief valve on the car. There are tens of thousands of auto parts today, but in the process we use, each part has its own working principle. Many people also call relief valves as safety valves. If this component is missing, the car will be perilous, or it will explode if it fails.

The bleed valve is automatically opened or closed according to the working pressure of the system during the operation of the entire vehicle. Many people may not know this component yet, or why it is used. The pressure relief valve can be divided into several types, a pressure relief valve called intake, and a pressure relief valve called exhaust, which are divided into internal discharge type and external discharge type. What does this thing do? How does it work? Listen to the editor one by one. When a certain part of the car is working, when the safety pressure reaches a certain level, it can automatically open the protection. In fact, we often see it in our lives. For example, northerners use pressure relief devices on heating systems, as well as air conditioning systems, including household liquefied gas stoves, pressure relief valves for liquefied gas, and natural gas. But we all know that there are two types of cars today.

There are many turbocharged models. If the pressure in the pipeline exceeds the standard, the air intake parts, the air intake pipe or the steel parts inside, may cause deformation when the pressure is too large to bear. Or it caused an explosion. Then the working process of the intake pressure reducing valve and the method of the exhaust pressure reducing valve are different. For example, when we release the accelerator, you think your feet are loose and stable, but there will definitely be changes. It is impossible to stay still. This process will lead to changes in the engine, that is, the vehicle is in the process of returning oil. The pressure of the intake air, at this time, the bleed valve will remove the air in it, reducing the pressure, thereby protecting the parts.

The exhaust pressure relief valve is to prevent the turbine from exceeding a certain pressure under the condition of continuous pressure, and is worried about damage to the turbine during the process, so a part of the air will be removed through the exhaust pressure relief valve. This kind of exhaust relief valve is different from a professional racing car or a specially modified car in life. In a family car that everyone uses, the air pressure valve maintains the boost pressure at a fixed level. The pressure relief valve starts to work when it exceeds this fixed level. The first is that it will not waste car kinetic energy, and secondly, it will not cause component failure.

In the process of use, when the pressure reaches the limit value, the pressure relief valve uses the connecting rod to push the special valve. In fact, it is very simple. In the process of use, when the air is full, the connecting rod will push the valve. Will be discharged. The main function of the exhaust pressure reducing valve is to reduce the pressure, protect the turbine, and protect the engine. The function of the intake pressure reducing valve is to protect the intake components. In fact, their biggest role is to protect the throttle.

The throttle is usually called the throttle, but it is not exactly the same. It is a component that controls the amount of air intake. The car you buy from the original factory, that is, the car that has not been modified, can ensure that the incoming gas is supplied to the engine. The intake port is used and compressed, and the excess unused is discharged to avoid entering the cylinder. During the whole process of use, if the pressure in front of the throttle is too high, the air pressure valve will lead you to the compressor impeller. If you do not introduce it, there will be a babble noise, which means that the air pressure valve is faulty. In the process of working, the turbocharger can compress the surrounding air and increase the amount of air intake to the engine, thereby making the engine more dynamic. Conversely, when the fuel is being collected, the throttle opening is reduced, or even in a closed idle state. At this time, the engine will not take in air, but the airflow still exists. Once this is the case, the throttle valve will be blocked, and the turbocharger will work during use.

Why do many people often say that when a turbocharged car stops, it stops for a while before turning off. In order to reduce the speed of the turbine, it is actually unnecessary at present. The turbocharger has been protected through the pressure relief valve, through the protection of the oil, and through the principle of the entire design. Turning off the flame after a pause is indeed a futile effort. On the other hand, during the idling process, there is still a steady stream of flowing into the intake pipe. At this time, the throttle in the intake pipe is closed because you are already idling, and the car no longer needs to push harder. It just needs to be on fire at idling speed. So much air is not needed, but you have just been driving on the road during this period of time. There is still a lot of high-pressure air in it. If this air is not discharged and stored in the intake pipe for a long time, it will have a great impact on the inside. It is often in a high-load working state, which will cause the throttle. Damage or even burst pipe.

Even if these problems do not appear, it will take a long time. If the intake pressure inside is too high, it will cause acceleration and deceleration to be unsmooth, especially during the acceleration process, it feels boring. Therefore, since the high-pressure air coming in in this process is not used, let it out. Install such a device in the intake pipe to effectively release the excess high-pressure air after compression, and the turbocharged intake air Valves are basically installed before turbocharging. When the incoming air is low, continue to enter the air and exceed the critical value, open the pressure relief valve to let the excess air out, so as to ensure the normal operation of the engine during use.

This is what we are telling you today about the function of the pressure relief valve on the car. In the process of using it, if there are some faults in the vehicle, many friends say that the vehicle has a hissing sound, and I don’t know if it is What's wrong, and there is also such a situation of poor acceleration? At this time, everyone should consider whether there is really a problem with the pressure relief valve on the car?
