6.8 ON-VEHICLE CLEANING
After the engine has been in operation for a
period of time, its fuel flow may be blocked or
become un-smooth owing to buildup of dust
and impurities in fuel channel. In addition, the
carbon deposits and gum made by combus-
tion can easily adhere to the injectors, inlet
and outlet ports, inlet and outlet hoses, thrott-
le and combustion chamber. So the fuel supply
system, combustion chamber and injector of
the engine must be cleaned on a timely basis.
Combustion Chamber cleaning is a solution
that can save your time and labor.
Procedures:
1) Please check if there is test liquid or deter-
gent inside the fuel tank before On-vehicle

with detergent.

tain ratio, and fill the mixture into the fuel tank.

been shown in “Connecting” below.
