Section II - SYSTEMS OPERATION
ENGINE. The M48A5 AVLB is equipped with a Continental Model AVDS-1790-2D, that is a 12
cylinder, 90°, V-type, 4 cycle, air cooled, turbo supercharged diesel engine.
Features of the
engine include:
l
28-volt direct current air-cooled generator (A) that provides vehicle electrical power.
l
28-volt solenoid operated starter (B) with circuitry that prevents starter activation
when vehicle batteries are improperly charged.
l
Intake manifold heaters (C) that preheat intake air for easier cold weather starting.
l
Turbosuperchargers (D) that increase air intake pressure to produce a high density air
that increases engine power.
l
Fuel filter (E) and fuel/water separator (F) that remove contaminants and water from
the diesel fuel.
l
Oil filter (G) and coolers (H) that keep engine
and transmission oil free of contaminants and
at operating temperature.
Cooling fans (J) that cool the engine by
drawing air from the engine underside
