If the leveling system makes unusual noise
or the alarm sounds when driving around
corners or over bumpy roads, this could
indicate a low

ENGINE - GENERAL INFORMATION
The diesel engine operates differently from
the conventional gasoline engine. Gasoline
engines control engine speed using a butter
fl
y
throttle plate to control air/fuel mixture inlet
fl
ow. As the throttle plate opens, vacuum
created by the piston velocity draws the
metered fuel/air charge into the combustion
chamber, then ignites from a controlled electric
ignition source. Closing the throttle plate limits
the fuel/air supply, slows engine speed and
increases intake manifold vacuum.
The diesel engine in the motorhome controls
engine speed by varying fuel supply only. No
throttle plates are used. An exhaust driven
turbine system (turbocharger) compresses the
fresh air supply into the engine. The fuel is
injected under pressure into the combustion
chamber. Ignition of fuel/air charge occurs
from heat generated by rapid high compression.
The turbo boost gauge registers amount of
intake manifold pressure measured in lbs./in².
Therefore, no intake manifold vacuum exists.
Diesel engine RPM (revolutions per minute) is
generally much lower than that of the gasoline
engine. Peak torque and horsepower output
values occur at much lower engine speeds.
Idle speeds between the two engine types are
similar, however, maximum engine speeds are
quite different. The gasoline engine generally is
not regulated to a maximum engine speed. The
maximum engine speed on a diesel engine is
controlled by an engine speed governor set by
the engine manufacturer.
WARNING:
DO NOT operate a diesel engine
where there are or can be combustible
vapors. Vapors can be drawn through
the air intake system and cause engine
acceleration and over-speeding,
resulting in fire, explosion and extensive
property damage. Numerous safety
devices are available, such as air intake
shutoff devices, to minimize risk of an
engine over-speeding where an engine
(due to its application) might operate in
a combustible environment, such as fuel
spills or gas leaks.
INFORMATION:
The equipment owner and operator is
responsible for safe operation of engine.
Consult your engine manufacturers
owners manual or authorized repair
location for more information.
