The air valve is connected to the air filter, and the exhaust valve is connected to the exhaust tube. In general, the intake valve of the used engine is cleaner than the exhaust valve. The door moves upward to open the exhaust valve, the spark plug opens the exhaust valve after ignition, and the intake valve opens before the ignition.

The engine exhaust valve mechanism directly determines the performance of the engine, and the exhaust valve in the entire exhaust valve mechanism is a vital component, so when the exhaust valve clearance changes, the engine performance will be biased.

The automobile exhaust system mainly emits the exhaust gas discharged by the engine, and at the same time reduces the pollution of the exhaust gas and reduces the noise. Automobile exhaust system is mainly used for light vehicles, mini vehicles and passenger cars, motorcycles and other motor vehicles. The automobile exhaust system refers to a system that collects and emits exhaust gas, and is generally composed of an exhaust manifold, an exhaust pipe, a catalytic converter, an exhaust temperature sensor, an automobile muffler, and an exhaust tail pipe.

The role of the valve is to be responsible for inputting air into the engine and exhausting the exhaust gas after combustion. From the engine structure, it is divided into intake valve and exhaust valve. The role of the intake valve is to draw air into the engine and mix it with fuel for combustion; the role of the exhaust valve is to exhaust the exhaust gas after combustion and dissipate heat.

Although exhaust systems found on many new vehicles are usually fully welded in their structures, exhaust clamps are still commonly found on exhaust systems of many vehicles. the exhaust clamp is a simple metal clip designed to hold the different components of the exhaust system together and seal together. They have different shapes and sizes to fit different types of exhaust pipes and can usually be tightened or loosened as needed. When the fixture fails or has any problems, it may cause problems in the vehicle exhaust system, which will affect the engine performance. Usually, bad or failure of exhaust fixture can produce some symptoms, which makes driver alert to potential problems.

We all know that the noise of traditional agricultural tractors is relatively large. The noise mainly comes from diesel engines and exhaust pipes, but the noise of small cars is very small. Why? On the one hand, a lot of sound-absorbing materials are installed in the engine compartment of the car; on the other hand, the exhaust muffler is installed in the car.

Nowadays, many people are not tired of refitting car exhaust pipes. There are many types of exhaust pipes, each of which has different functions. With a modified exhaust gas, it feels a little less without changing the tailpipe. But do you know how to choose the exhaust tip modification?

Sometimes small things make a big difference between a good-looking car and a good-looking car. Your paint looks great, but if you don't take the time to properly detail the areas such as wheels, hub holes, glass or vents, the work can not be done. Perhaps the most often overlooked area is the vent. Ignoring them can be a bit of a hassle, but it's actually very simple and does n' t take a lot of time to get the job done correctly. After detailing the exhaust technique, it not only makes the car look better, but also prolongs the service life of topcoat, which is usually stainless steel or chromium alloy. Similar to hub maintenance, if ignored, the finish of the exhaust head will start to corrode, sag or discolor. However, if they are maintained regularly, they will remain beautiful for a long time.
