Figure 3.1.3 – Diagram of the engine lubricating system
The engine feed system consists of the included into the engine package fuel pump
15 (figure 3.1.2), nozzles 14, low pressure pipes, high pressure fuel lines, inlet manifold,
outlet manifold, turbocharger 6, coarse fuel filter 2 (figure 6.4.12), fine fuel filter 1 (figure
6.4.29) and also contains an air cleaner, fuel tanks, charged air cooler and a muffler
mounted by MTW.
High pressure fuel pump (HPFP) has a block construction consisting of six injection
units in one housing, having plunger tappet drive and a spool-type dosing of cyclic fuel
supply. HPFP is intended to supply measured amounts of fuel under high pressure to the
engine cylinder combustion chambers at the specific time. Fuel pump camshaft drive is
carried out from the engine crankshaft through timing gears. The fuel pump is combined
into one device with an all-speed governor having a fuel supply corrector, an automatic
fuel supply fortifier at startup rounds, a pneumatic smoking limiter and a fuel priming pump
of piston type. High pressure fuel pumps PP6M10li manufactured by “Motorpal” plant are
equipped with the startup solenoid which provides fuel supply increase while starting the
engine.
Priming pump 16 (figure 3.1.2) is mounted on the HPFP housing.
