LOCATION AND DESCRIPTION OF MAJOR COMPONENTS - CONTINUED
AIR INTAKE MANIFOLD
A hollow aluminum casting, mounted to cylinder head assemblies on drivers side of engine. It
receives intake air from turbocharger through air crossover connection and delivers it to intake ports
of each of three cylinder head assemblies.
ANEROID CONTROL VALVE
An air intake manifold pressure-controlled valve, mounted at fuel pump outlet line, to create a delay in
fuel supply line equal to the delay or lag of intake air pressure caused by slow turbocharger speed
buildup. Aneroid control valve eliminates excessive exhaust smoke caused by high fuel-to-air ratio.
LUBRICATING OIL PUMP
A geardriven gear pump, mounted on left side of engine, below air compressor. It draws lubricating
oil from oil pan and circulates it, under pressure, through engine oil passages. An integral pressure
regulator controls the lubricating oil pressure.
