1.Brief description of the struc鄄
ture
Accelerating transmission device is
composed of accelerator pedal
mechanism尧 accelerator drawing
wire and speed governor handle of
the engine. (As shown in the figure
above)
When depress the pedal, driving de鄄
vice of the mechanism pulls the
drawing wire and controls the open鄄
ing extent of the accelerator to in鄄
crease or decrease the speed
1) Accelerator pedal mechanism:
This mechanism adopts the latest
structure of ISUZU truck. It operates
simply and reliably and is connected
to the accelerating drawing wire and
the hand throttle drawing wire; struc鄄
ture of the pedal adopts injected
molding type, which makes the as鄄
sembly convenient and causes little
operating noise.
2) Accelerating wire drawing:
It operates with soft drawing wire
and has a reliable structure; it爷s
characterized with convenient layout尧
little frictional resistance and stable
transmission.
3) Manual throttle drawing wire:
When Used together with the foot
throttle, it can quicken the preheating
of the engine or increase the idling
speed.
2. Using and adjustment
1) Check whether the connecting po鄄
sition of the linkage rod and the ac鄄
celerator mechanism is right and reli鄄
able; check whether the trend of the
drawing wire is straight and check
the corners for smooth transition.
2) The pedal should be depressed
easily and to the extreme position
without jamming. When released, it
should return freely.
3) When depressing the pedal, if the
free play is too large or the opening
degree of the accelerator is insuffi鄄
cient, adjust the position of bolts to
make it return safely.
渊郁冤 Fuel supply system
1.Brief description of the struc鄄
ture
Fuel supply system is composed of
fuel tank尧 fuel filter尧 fuel pump尧fuel
injection pump尧 fuel inlet pipe and
fuel return pipe.
The function of the fuel supply sys鄄
tem is to inject specified quantity of
diesel well atomized into the cylinder
regularly with definite interval of in鄄
jection and under definite pressure
according to the engine -operating
requirement as well as make the
diesel mix with the air well and
rapidly. Operating state of fuel sup鄄
ply system has great influence on
power and economic performance of
the engine.
Strainer: A rotating precipitator of D伊
200M type (as shown in the right pic鄄
ture) that can filtrate great grain im鄄
purity and separate oil from water is
equipped to the fuel pipe.
2) Fuel tank: Capacity of the fuel
tanks of HFC1045 trucks is 90 L; a
lock is installed to the fuel tank cover
as well as a strainer to inside of the
fueling opening to prevent impurity of
large grain coming into the fuel tank.
Oil -draining plug is installed to the
lowest position of the lower side of
the fuel tank for sake that it爷s conve鄄
nient to drain the deposit and water
in the bottom of the fuel tank in
cleaning.
