FUEL SYSTEM
Leakage time (waste)
Pressuremustdropfrom150to100barsinaspanofnotlessthan8secondsandnotmorethan30.
Seatseal
Nozzletipwet.
Pressuremustbekept20barsbelowtheopeningpressurefor10seconds.
Afterthistime, dampness onthenozzletipisacceptable,andmaybeidentied bytouchingwithadrynger.Onlya dropof
dampnessisacceptableandnotalargethickpatchwhichwouldindicatealeak.
Injector calibration
Connect the injector to a hand pump and adjust if necessary,
modifyingthethicknessabovethespring.
When the spring is replaced, calibration must be carried out at a
pressure higher than 10 bars to counterbalance adjustments while
running.
Spraying and opening pressure
With the pressure gauge closed, press hard on the hand pump at
least10times.
Open the pressure gauge and press down on the pump once every
second,whilekeepingacheckonthesprayingprocessandpressure.
The opening pressure must lie between the two values given in the
table.Jetsmustbeuniformandwelldistributed.
*Thesevaluesapplytonewinjectorandallowforlooseningofupto10%afterbreaking-inperiod
Nozzles
Theset-up betweentheneedleandtheguidemustleavetheneedle
freetofallandmerelyasaresultofitsownweight,whenlifted7mm
fromitsseatandrotatedindifferentdirections,withthenozzlekeptat
a45°angle.
Rotationoftheneedlemustbecompletelysmoothanduninhibitedby
obstaclesandmalformations.
Moreover,onbeingsqueezedagainstitsseat,itmustfallfreely,when
thenozzleisinverted.
Thetestmustbecarriedoutafterrinsingboththeneedleandnozzle
with trichloroethane and wetting with ltered SHELL CALIBRATION
