The auto accessories trade show teaches you how to remove carbon deposits from car engines. Regular cleaning is generally divided into three steps. The cleaning of the fuel injection nozzle and the air inlet can remove part of the carbon deposits and soften the deep carbon deposits. The fuel filler is added to the fuel tank to continuously clean the carbon deposits and restore the fuel injection. The atomization effect of the mouth keeps the oil passage open, restores the engine's power, eliminates the engine's cold start difficulties, and idling instability, improves fuel economy, and extends the service life of the spark plug, oxygen sensor, three-way catalyst, and engine.

The auto parts expo selects the gasoline suitable for the model number according to the manufacturer's instruction manual, but it needs to be explained that the gasoline number represents the octane number of the gasoline, and reflects the anti-knock of the gasoline, the gasoline number and the gasoline. The quality of the product cannot be digressive. It is recommended to refuel at a regular reputable gas station. Due to crude oil and refining processes, coupled with the fact that the gasoline sold on the market is not high-quality gasoline, gasoline components contain sulfur and phosphorus, especially olefins. The content is high and the oxidation stability is poor. During the internal combustion process of the engine, the olefin will be oxidized and condensed to form a colloid. It will collect with the dust particles in the engine crankcase exhaust gas and intake air, and form a connection at the throttle body, intake manifold, etc carbon.

In addition, driving habits and conditions of use are also very important. Poor driving habits of "high-end and low-speed" driving will cause insufficient combustion of the mixture and easily generate carbon deposits; Mercedes-Benz truck maintenance reminders to avoid long-term engine idling and low-speed vehicles. You should always run at high speeds. High speeds can make the mixture fully burned, improve fuel economy, reduce the formation of carbon deposits, restore the sensitivity of the oxygen sensor, and clean the carbon deposits between the spark plug electrodes and the surface of the three-way catalyst.

The auto parts exhibition teaches you how to effectively reduce the noise of your car. Many car owners feel this way. When driving, especially at high speeds, car noise has become the main factor affecting the driving environment. People's long-term exposure to noise can cause tinnitus, dreaming, panic and irritability, or directly cause hearing loss or even hearing loss. Traffic accidents indirectly caused by vehicle noise are not uncommon. Confidence Classics fast repair beauty chain professional technicians introduced that car noise is roughly derived from engine noise, exhaust noise, fans, transmission systems, braking systems, tires and wind noise, etc., and through the modification of the day after tomorrow, most of the noise can be effectively reduced Come down.

Before making the sound insulation of the car, you should check the condition of the car. Some noise is caused by the failure of the vehicle itself, such as abnormal tire pressure, irregular wear, suspension or chassis damage, and abnormal noise of the engine. The system's sound insulation project is mainly completed by three steps: vibration reduction, noise reduction and sealing. Among them, the door, trunk, chassis, hood and roof are the places where air friction noise is most likely to occur. Therefore, these places are the focus of noise reduction. For engine noise, it is best to paste an advanced sound-absorbing foam acoustic material under the hood, which can absorb and consume a large amount of engine noise, and can also suppress the hood vibration and block the heat from the engine, and protect the paint surface Not subject to high temperature damage. According to Volvo truck maintenance understanding, through professional construction technology, without damaging the original car circuit and changing the original car structure, the sound insulation project can reduce the noise in the car by 4-8 decibels, greatly improving the driving comfort.
