Tips for car maintenance, grasp the timing of shutting down after commercial vehicle modification to

Car carbon deposits have always been the most troublesome maintenance step for car enthusiasts, but if good driving habits are taken into account in daily driving, the formation of car carbon deposits can be greatly improved and reduced. Here are some basic techniques to be introduced.

1. Use clean gasoline

Impurities in gasoline are the main components of carbon deposits, so gasoline with high cleanliness has a weaker tendency to form carbon deposits. However, it should be noted that high grade does not necessarily mean high quality. The grade only represents the octane number of the oil, not the quality or cleanliness. Some car owners may add gasoline detergent to the gasoline to ensure the cleanliness of the gasoline. This can effectively prevent the formation of a carbon deposit layer on the metal surface, and gradually activate the original carbon particles and slowly remove them, thereby protecting the engine from damage. However, adding gasoline detergent must be cautious, because adding counterfeit products may have the opposite effect.

2. Do not idle for a long time

The longer the idling time, the longer it takes for the engine to reach normal temperature, and the slower the evaporation rate of gasoline when it is sprayed on the back of the valve, resulting in the formation of carbon deposits. At the same time, frequent idling reduces the airflow entering the engine, weakens the flushing effect on carbon deposits, and promotes the deposition of carbon deposits.

3. Pay attention to the timing of engine shutdown

For cars equipped with turbochargers, do not turn off the engine immediately when driving at high speed or climbing. Turn off the engine after idling for 10 minutes. The speed at which cars equipped with turbochargers form carbon deposits is several times faster than ordinary naturally aspirated cars.
The commercial vehicle modification master recommends that some car enthusiasts perform free disassembly and cleaning of the intake system every 20,000 to 40,000 kilometers under the condition of meeting regular maintenance. This means that without disassembling the engine, special equipment and methods are used to clean carbon deposits in the intake pipe, valves, oil circuits and other parts of the vehicle that are prone to carbon deposits.
