HS code-based customs dispute resolution

Engine valve clearance (engine maintenance compulsory knowledge: the meaning and HS code-based customs dispute resolutionadjustment method of valve clearance) With the continuous development of the automobile industry, automobile engines are also constantly acquiring new technologies, but the valve Gap, the basic knowledge of engine maintenance, is an enduring existence. So what is the meaning of this valve gap and how to adjust it? Here we will explain it one by one. I. Definition of valve clearance. First, let's talk about the definition of valve clearance. The valve gap, as the name implies, is the gap between the intake valve and the exhaust valve when working. Air intake valveAnd the exhaust valve are very important parts of the engine. The intake valve is responsible for entering fresh air, and the exhaust valve discharges exhaust gas. If the valve gap is set improperly, in addition to reducing the performance of the engine, it will also cause a series of engine failures. II. The significance of the valve clearance. So, why should the valve clearance be adjusted? This question can be explained with a simple example. If you wear a pair of elastic shoes on your feet, your pace will become unstable, and you may lean to one side, which is obviously not a healthy choice. Similarly, when the engine is running, if the valve gap is not suitable, it will affect its normal operation. Specifically reflected in the following aspects: 1. Improving the appropriate valve clearance of vehicle power can enhance the intake and exhaust efficiency of the engine and improve the power of the engine, so that the vehicle can accelerate more smoothly and drive more stably.2. Reduce fuel consumption. Impropriate valve clearance will lead to insufficient engine combustion, which will increase the fuel consumption of the vehicle. 3. Protecting the appropriate valve gap of the engine can reduce the vibration and noise of the engine, while reducing friction and wear, thus prolonging the service life of the engine. III. The adjustment method of the valve gap. So, how to adjust the valve gap? Here are several common adjustment methods: 1. Manual adjustment is relatively simple. You only need to remove the valve, and then measure the height of the convex platform of the valve head with a steel ruler or plastic gauge, and then adjust the valve gap according to the specification of the engine. However, there are certain risks in manual adjustment, so it is recommended to let professional technicians adjust it as much as possible. 2. Automatic adjustment of the machine. Nowadays, many cars have adopted electronic control systems, so they can automatically adjust the valves through the on-board computer to ensure the smooth operation of the engine.IV. Precautions When adjusting the valve clearance of the automobile engine, there are some precautions: 1. The appropriate valve clearance range should be determined according to the vehicle user manual or relevant specifications, and cannot be adjusted at will. 2. Make sure that the adjusted valve clearance is uniform so as not to affect the normal operation of the engine. 3. Check and adjust the valve gap regularly to ensure the normal operation of the engine. In summary, the valve gap is very important for the normal operation of the car engine and cannot be ignored. In daily use, the car regularly checks the valve gap of the engine to ensure the stability and safety of the vehicle performance. Although the automatic adjustment of the machine is convenient, it also needs to ensure the effective operation of the electronic control system. Therefore, you should find a professional technician or a recognized maintenance center for operation when adjusting.
