What is The Cause of Carbon Deposits In Cars?
Friends who often drive know that carbon deposits can bring a lot of inconvenience to driving, such as vehicle shaking, driving weakness, speed difference, increased fuel consumption, and even cause the engine to be scrapped. This phenomenon is often caused by the driver's driving errors. So, what are the four misunderstandings that lead to carbon deposits in cars?
The so-called carbon deposits refer to a kind of burnt substance produced by unsaturated olefins and colloids in fuel at high temperatures during the operation of the engine. Impurities such as wax and glue in gasoline are the main components of carbon deposits.
What are the four misunderstandings that lead to carbon deposits in cars? The specific contents are as follows:
The first mistake: Cleaning does not cause carbon deposits in cars.
The quality of fuel additives varies, and some fuel additives are prone to corrosion, which can prevent the formation of carbon deposits on the metal surface, and can gradually activate the original carbon deposit particles and slowly remove them. This method is simple and easy to use. Just add an appropriate amount of additives to the fuel tank together with gasoline. At the same time, the chemical cleaning components in the fuel additives have a certain corrosive effect on the rubber fuel supply pipeline. When using this method, you must pay attention to the use cycle and interval time, otherwise it will accelerate the aging and corrosion of the fuel rubber fuel supply pipeline.
The second misunderstanding: high-speed pulling can avoid carbon deposits.
What are the four misunderstandings that cause carbon deposits in cars? Many car owners believe that high-speed pulling can prevent carbon deposits, but it does not have a good cleaning effect on carbon deposits, has strong adhesion and is extremely stubborn, on the contrary, it only consumes gasoline. High-speed pulling cannot completely remove carbon deposits.
On the one hand, the correct treatment method is to delay the generation of carbon deposits by intermittent high-speed or high-speed driving. On the other hand, if there is carbon deposits, it must be thoroughly solved by cleaning. For the method of non-disassembly (drip) or disassembly cleaning, it is necessary to determine the location and degree of carbon deposits.
The third mistake: low-speed driving can effectively save fuel.
Some car owners think that as long as the engine shifting and driving speed are reduced, fuel can be saved, but in fact, it does not save the car. The biggest problem is carbon deposition. In the case of high-speed and low-speed, the engine is not only prone to knocking, but also has a slow intake speed. At this time, fuel evaporation may cause carbon deposits in the intake manifold and other parts.
The fourth mistake: the longer the idle time, the better.
This is not the case. If the idle time is long, the engine will take a long time to reach normal temperature, and the gasoline will evaporate more slowly after being injected into the valve, thus producing carbon deposits. At the same time, at idle speed, the air flow entering the engine is also small, so the erosion of carbon deposits becomes weaker, which will promote the deposition of carbon deposits.
