Specifications

The governor control mechanism features two operator controlled levers. The diesel
engine RUN lever places tension on a spring attached to the governor lever. The
tension places the governor lever in a position to allow fuel flow to the fuel injector for
diesel engine start up and to allow the diesel engine to continue running after start up.
The diesel engine shutdown or STOP lever is operated by either depressing the red
STOP lever or by the low oil pressure shutdown system. When depressed, the lever
trips the RUN lever releasing the tension on the governor spring which places the
governor lever in a no fuel or stop position. This action shuts off fuel flow to the fuel
injector stopping the combustion process and shutting down the diesel engine
Engine Electrical Starting System
The diesel engine electrical starting system can be used to start the diesel engine
whenever there is a 12 VDC power source connected. Aurora generators have a battery
included with the generator that may already be connected. When the generator is
running, it recharges the battery. Electrical Starting will be required when starting the
diesel engine in extremely cold weather or as a backup to the manual starting system
found on the open frame type generators. The electrical system also provides a means
for warming diesel engine intake air which also helps to start the engine in cold weather.
The system consists a momentary contact switch located on the generator electrical
panel.
Starting the engine with the starter motor is possible when the operator places the start
switch in the START position, power is applied through the switch to the starter
solenoid. This energizes the coil in solenoid which pulls in the solenoid's plunger and
pushes the starter drive pinion attached to the plunger toward the engine flywheel. This
movement engages the starter pinion drive with the ring gear teeth on the diesel engine
flywheel. As the solenoid plunger pulls in, the power available at solenoid pin S is
applied via a jumper to the starter motor which rotates the starter pinion drive (part of
the starter motor) and turns over the flywheel engaged with the pinion drive to start the
diesel engine. Immediately after the diesel engine starts, the generator set operator
releases the START switch. This opens the solenoid-starter circuit causing the solenoid
plunger to release the starter pinion drive disengaging it from the engine flywheel ring
gear. At the same time, the starter motor is de-energized. The starter pinion will return to
its normal position as the starter motor slows to a stop.
When your generator is running, the battery is automatically kept charged. A charge
regulator is mounted on the side of the engine and gets its power from the generator. A
dead battery or very low charged battery can overload and damage the built in charger.
Never use a low charged or dead battery.
Engine Pre-Heating
Preheat Circuit. The diesel engine features one 12-VDC resistance-type heater located
in the engine air intake piping between the intake manifold and the air cleaner. The
