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.
