Diesel Fuel Injection

System

The diesel engine in this Arctic Cat ATV is a “compres-

sion ignition” engine. Extremely high pressure in the

combustion chamber raises air temperature high enough

to cause ignition of the fuel upon injection into the com-

bustion chamber. No spark is present or required for igni-

tion.

In this style of engine, diesel fuel is drawn from the fuel

tank by a low pressure lift pump. From the lift pump, fuel

is pumped through the fuel filter/fuel shut-off and deliv-

ered to the fuel rail. Low pressure fuel at 0.42-0.56 kg-

(6-8 psi) flows to the unit injectors (high pressure

fuel pump/fuel injector) where the fuel pump, driven by a

special lobe on the camshaft, increases the fuel pressure

to 143-153 kg-cm

(2030-2175 psi). At this point, the

fuel is atomized by the fuel injector nozzle as it enters the

combustion chamber.

Fuel in excess of the amount required for any particular

power setting is directed back into the fuel return side of

the fuel rail and routed back to the fuel filter head where

it either recirculates or is returned to the fuel tank via the

fuel return hose.

Fuel flow is shut off when the ignition switch is turned to

the OFF position. A fuel solenoid valve is located on the

fuel filter head and opens the valve whenever a 12 DC

volt current is applied to the solenoid.

Lift Pump

REMOVING

1. Remove the banjo-fitting bolts securing the fuel

hoses to the lift pump; then remove the two nuts

securing the lift pump to the cylinder head. Account

for four crush washers, an O-ring, and two flat wash-

ers.

DE078B

DE309A

2. While holding pressure against the lift pump push

rod, rotate the engine until the push rod is fully

retracted.



NOTE: If pressure is not applied to the push rod

while rotating the engine, the push rod may become
dislodged from the eccentric ring requiring valve
cover removal to relocate.

INSTALLING

1. Using a new O-ring, place the fuel pump onto the

cylinder head and secure with the existing hardware.

Tighten the nuts alternately until the fuel pump is

seated against the head; then tighten securely.

DE530

2. Connect the fuel inlet and lift pump outlet hoses to

the fuel lift pump using new crush washers and

secure with the banjo-fitting bolts. Tighten securely.
