In particular, gasoline storage for a long time will go bad. In particular, LPG and gasoline dual fuel
engine in a taxi, long-term with LPG as fuel, gasoline is used for starting, gasoline consumption
rarely. But the fuel pump in long-term operation, oil temperature is high. If gasoline is stored in the
fuel tank, it is very easy to be oxidized, may cause the injector blockage or damage.
5) Installation notes
The fuel injector must must use certain plug, not mix.
In order to facilitate the installation, recommended the O ring is connected with the fuel distribution
pipes, and clean the oil surface of the lower O ring is connected with the intake manifold mounting
hole is coated with no silicon; to clean oil coated with no silicon surface fuel injector and the intake
manifold fuel distribution pipe mounting hole. Be careful not to let the oil pollution inside the
injector and nozzle.
The fuel injector to be perpendicular to the direction of the oil injector seat into the injector seat,
and then use the fuel injector is fixed on the spray clip
Oil filter base. Be careful.
The injector clamp by positioning for axial positioning clamp and axial and radial locating clamp,
should avoid misuse.
Fuel injector for the axial positioning of the installation slot, should ensure bayonet clip
intermediate completely card into the injector, card slot clamps on both sides of the complete card
into the outer edge flanging injector seat.
③
And injector axial and radial positioning requirements should be used for the axial and radial
locating clamp and the positioning of injector and fuel injector seat positioning pins are respectively
located at the card groove clip in the corresponding installation.
④
If fuel injector with two card slots, care should be taken not to card error, can refer to the original
installation position.
Fuel injector installation manual, no knocking injector with a hammer and other tools.
Removing and reinstalling the injector, must replace the O ring. At this time no damage on the
sealing surface of fuel injector.
Bearing washer O ring shall be pulled out from the injector. When installation should avoid damage
into the oil injector end, O ring, support ring, the orifice plate and the electric plug. If damaged,
should be banned.
Install injector fuel distribution pipe assembly tightness detection. No leakage of Fang Wei
qualified.
Failure to use manual disassembly. Remove the injector clamp, and then from the injector seat out
of fuel injector.
After the demolition should guarantee the injector seat clean, avoid pollution.
6) Fault phenomenon and judgment method
Fault phenomenon: idling bad, bad acceleration, can not start (starting difficulty); or the high fuel
consumption, exhaust black smoke.
General failure: due to lack of maintenance, lead to the injector internal glial accumulation and
failure, or a cylinder injector does not work; a cylinder injector often injection etc..
Note: repair (see installation notes)
A simple method to measure:
(unloading joints) digital multimeter to Ohm, two probes are respectively connected injector two
pin, 20
℃
rated resistor of 12.
Suggestion: analytical instrument for regular cleaning of fuel injector using special injector
cleaning.
