SYSTEMS OPERATION - Continued
VEHICLE EXHAUST DUST EJECTOR SYSTEM (VEDES).
The vehicle exhaust dust ejector
system (VEDES) replaces the air cleaner centrifugal fans.
The air cleaner housing is modified
to plug the fan exhaust elbows and to accommodate a tube manifold with its associated hoses,
clamps, and mounting bracket installed in place of the fans.
A system of dust scavenger tubes,
check valves, and exhaust pipes with integral dust ejectors is mounted along each cylinder bank
above and parallel to the engine and transmission oil coolers. VEDES scavenges dust from the
precleaned section of the air cleaners through suction action of the exhaust ejectors.
DUST DETECTOR SYSTEM.
The Dust Detector System is to alert the driver when the air
induction system allows dust to bypass the filter.
The Dust Detector System uses engine air induction manifold pressure to circulate air through
filter strips in the dust detectors mounted in the turbosupercharger compressor housings. When
the filter strip(s) become clogged, the resultant change in pressure actuates a pressure switch
which illuminates the powerplant warning light and the dust detector warning light in the
driver’s compartment.
