Engine Idling
Avoid prolonged idling, long periods of idling may be
harmful to your engine because combustion chamber
temperatures can drop so low that the fuel may not burn
completely. Incomplete combustion allows carbon and
varnish to form on piston rings, cylinder head valves,
and injector nozzles. Also, the unburned fuel can enter
the crankcase, diluting the oil and causing rapid wear to
the engine.
Stopping The Engine
After full load operation, idle the engine for a few
minutes before shutting it down. This idle period will
allow the lubricating oil and coolant to carry excess heat
away from the turbocharger.
NOTE:
Refer to the following chart for proper engine
shutdown.
