FUEL SYSTEM
FUEL SPECIFICATION FOR PACCAR MX-13 DIESEL
ENGINES
Based on the present status of PACCAR MX-13 engine development, the
fuel (compositions) used must meet certain international standards to be
assured of the required engine performance, durability and emission goals.
Therefore PACCAR prescribes for all its engines that:
Any diesel or alternative fuel mixture must fully comply with European
Fuel Standard EN 590. Biodiesel must comply with European Biodiesel
Standard EN14214.
Fuel additives are not permitted.
Based on gathered knowledge concerning the effects of alternative fuels,
PACCAR supports the following rule:
Alternative fuels and mixtures of diesel fuel for PACCAR MX-13 powered
vehicles are allowed, if officially produced diesel or blends with alternative
fuel up to a maximum of 7% biodiesel according to standard EN590 are
used. Using a fuel with a biodiesel blend will a more regular service
schedule, discuss with an authorised Kenworth dealer.
To prevent condensation while the vehicle is parked for extended periods,
do not overfill the tanks above 95 percent of capacity, 95 percent is to the
lower edge of the filler neck so that air gap is clearly visible, as this provides
room for expansion resulting from temperature extremes (see page 209).
FUEL SYSTEM PRIMING
The PACCAR MX-13 fuel system incorporates two filtration units. A fuel/
water separator with primary filter mounted to the left hand chassis rail
and a main filter cartridge mounted on the left hand side of the engine.
The priming pump button on the primary fuel filter (2), must be used
correctly to prevent premature failure. To prime the complete fuel system,
ensure the bleed vent (3) on the main fuel filter is open before using the
priming pump button on the primary filter.
DO NOT crack injector lines to bleed fuel system. This is not required and
will render the fuel lines unserviceable and require replacement.
