Many car owners’ friends do not pay attention to the maintenance of the fuel system and do not know what kind of hazards the fuel system is not clean. Here's how to clean the fuel system.
Q: Why is there a deposit in the fuel system?
Answer: The formation of deposits is directly related to fuel. The first is that the automobile itself contains gums, impurities, dust, and so on. Over time, deposits similar to sludge are formed at fuel tanks, inlet pipes, etc.; secondly, unstable components such as olefins in gasoline undergo oxidation and polymerization reactions at certain temperatures. Gum and resinous stickies are formed. These sticky materials stay in the nozzles, intake valves, etc. The deposits will become hard coke when burned. Traffic jams, cars are often at low speed and idling, and they will increase the formation and accumulation of sediments.
Q: What are the hazards of unclean fuel system?
A: First, deposits can clog the needle valve and valve hole of the injector, affecting the performance of the precision components of the electronic injection system, resulting in a drop in power performance. If it is a carburetor engine, sediment will accumulate in the carburetor, especially near the idle speed hole, causing the engine to idle fast, easily turning off, and increasing fuel consumption. Secondly, deposits form carbon deposits in the intake valves, causing them to close down and causing the cylinder pressure to drop or even temper, which leads to unstable engine idle speed, increased fuel consumption, and worsening exhaust emissions. Again, deposits can form a hard deposit on the top of the piston and the cylinder head, which can easily cause local overheating of the combustion chamber, flaming of the gasoline, and engine knock. In addition, the life of the three-way catalytic converter will also be shortened.
