9.3 Fuel consumption is too large
(5) injector or nozzle assembly doesn't
work normally (5) Clean, regulate
The cause of the fault Elimination method
(1) Fuel leakage
(2) idle speed is too high
(3) the max rotation speed is too high
at the no load
(4) injection timing is abnormal
(2) regulate idle speed
(3) check the max speed set bolt of the
injector pump
(4) regulate the injecting timing
9.4 The power is not enough
The bolt of the cylinder is loosened
The cause of the fault
(1)The air cleaner is too dirty and the
fuel is restricted
(2) The throttle doesn't work normally
(3) Fuel pipe is clogged,
(4) There is leakage or there is some air
in the fuel system
(5) The speed-regulation spring is slack
(6)The timing of the supplying fuel is not
correct.
(7) There are some faults in the injector
(8)The air cleaner is too dirty
(9) Mix air phase or valve clearance isn't
correct
(10) The compression pressure of the cylinder is not enough
There is air leakage at the valve
There is air leakage at the cylinder
cushion
The cylinder, piston ring or piston is
worn out
There is air leakage when install the
injector
Tighten the bolt again as required
Elimination method
(1) Clean and replace
(2) Regulate the throttle
(3) Check and clean
(4) Tighten it again, eliminate the air in
the system
(5) Regulate the max speed limited screw
(6) Regulate it as specified
(7) Check the pressure of oil injection
and atomization condition
(8) Clean and replace the element
(9) Check and regulate it
Abrade the surface or replace the
valve and valve base ring
Replace the cylinder cushion
Replace the relative parts and abrade
the cylinder surface
Replace the seal gasket or adiabatic
line of the nozzle
(1) replace or tighten securely
