EFI engine is currently on the vehicle use a very wide range of equipment, compared with the conventional carbureted fuel system, EFI engine fuel supply system, not only complex, but also parts with precision. When using Auto Diagnostic Tool maintenance necessary to pay special attention.
During cleaning maintenance, some parts can not be disassembled and dismantled, some parts assembly requirement is high, which makes gasoline injection system than the carburetor type vehicles are more vulnerable to the dangers of gasoline in the colloid, sediment, the cleaning is very complex.
The engine fuel supply system, the air inlet and exhaust system are clean and have a decisive influence on the driving performance of the vehicle. Due to the impact with the environment and fuel quality injectors, intake manifold, intake and exhaust valves and the combustion chamber is easy to produce gelatinous precipitates, etc., affect the normal fuel supply, cause by fuel injection quantity control is not accurate, the fuel spray is bad, the oil pressure regulation failure, which causes the engine idle speed instability, the acceleration bad, knock, lack of fire, fuel consumption, exhaust emissions exceed the failure phenomenon. These faults can be using the Launch X-431 PAD or Launch X431 Creader VIII tool checked out.
In order to clean the oil supply system to solve the problem from the inside, they usually avoid demolition clean way. Vehicle cleaning jobs by special Autel MaxiDas DS708 or Autel Maxidiag Elite MD701 tools and equipment and cleaning agents, under certain pressure and flow control, intake manifold, fuel injectors, intake and exhaust valves and combustion chamber thorough cleaning to restore the normal operation of the fuel system, to ensure good driving performance of the car.
