Avoid Unnecessary Idling; Stopping The Engine; Emergency Jump Starting - Detroit Diesel MBE 900 Operator's Manual

Avoid Unnecessary Idling

Whenever possible, avoid unnecessary
idling.
During long engine idling periods
with the transmission in neutral, the
engine coolant temperature may fall
below the normal operating range.
The incomplete combustion of fuel
in a cold engine will cause crankcase
oil dilution, formation of lacquer or
gummy deposits on the valves, pistons,
and rings, and rapid accumulation of
sludge in the engine. When prolonged
idling is necessary, maintain at least
850 rpm spring/summer and 1200 rpm
fall/winter.

Stopping the Engine

Stop an engine under normal operating
conditions as follows:
1. Reduce engine speed to idle and
put all shift levers in the neutral
position.
NOTICE:
Stopping a turbocharged engine
immediately after high-speed
operation without allowing a
sufficient cool-down period may
cause damage to the turbocharger,
as it will continue to turn without an
oil supply to the bearings.
2. Allow the engine to run between
idle and 1000 rpm with no load

for four or five minutes. This
allows the engine to cool and
permits the turbocharger to slow
down. After four or five minutes,
shut down the engine.

Emergency Jump Starting

The DDEC VI system operates on 12
volts DC. If a DDEC VI engine with
an electric starting motor requires
emergency jump starting, do not
exceed 16 volts DC.
BATTERY EXPLOSION
To avoid injury from battery
explosion when jump starting the
engine, do not attach the cable
end to the negative terminal of
the disabled battery.
