You can look at the carbon black in the exhaust pipe first. Generally speaking, engine carbon deposit and automobile exhaust are twins. Carbon deposition is constantly produced, just like dust in daily life. Only by constantly cleaning up the carbon deposit can the automobile exhaust not exceed the standard. How to judge whether the exhaust gas will exceed the standard? Is the carbon deposition in the engine serious? First, learn a simple judgment method: car: observe the exhaust pipe. I hope you can become an expert in engine carbon deposition and automobile exhaust. The tail gas pipe has the following conditions
1/ Carbon-free: Wipe the exhaust pipe with white paper, which is only light yellow. = = The engine has no carbon deposit and the tail gas is odorless. .
2/ Floating carbon: In the same way, it was found that there was a little black carbon in the exhaust pipe, and there was little left after a light pat = =, and the engine was normal. The exhaust gas is basically odorless.
3/ Carbon thickness: Similarly, it is found that the black carbon in the exhaust pipe is very thick. There is still a lot of black carbon after typing the white paper, which needs to be cleaned up in time. You can smell gasoline.
4/ Oil carbon: In the same way, it is found that white paper has black carbon, oil stains, burning oil, and the exhaust gas will be large and pungent. Need to be repaired in time. Otherwise, it is not a problem of cleaning up carbon deposits and tail gas.
5/ Oil carbon deposit and smoke: Due to carbon deposit and other reasons, it can be judged that the engine has serious problems. Need professional car repair.
6/ If the spark plug is removed, the basic judgment method is the same, that is, look at the spark plug head for carbon deposit and oil. It is judged that there are seven colors of automobile exhaust and carbon deposit.
7/ buckle space: 97629 Mountain Temple-use-dp engine beauty device -30 minutes to clean the engine carbon deposit, 300,000 kilometers of net exhaust gas saves fuel. -Use the-dp engine beauty instrument to clean the engine carbon deposit for 30 minutes, which means: put a white towel at the exhaust pipe, step on the gas pedal, and see carbon black particles on the white towel, which proves that the carbon deposit has been cleaned up; Fuel-saving of 300,000 km net exhaust gas means that when the carbon deposit in the engine is cleaned up, there will be less carbon in the exhaust pipe of the automobile until there is no carbon black. Because the carbon deposit in the engine is cleaned automatically, the automobile exhaust has no smell of gasoline. Carbon removal = fuel saving = net exhaust gas /qq space: Liumi Erjiu Mountain Temple in 1997.
