1.3 ENGINE
The engine is a vertical, in−line four cylinder diesel
engine, which is direct−connected to the alternating
current generator. Information on the major engine
systems is provided in the following subparagraphs.
1.3.1 Electronic Governor Module
The electronic governor module (EG) is a solid state
control module preprogrammed for 1800 RPM high
speed and 1500 RPM low speed operation. The
electronic governor module, along with the engine
speed sensor, replaced the manual governor in order to
provide constant and economical engine speed.
The unit has an LED which may be used to diagnose
failures within the electronic speed control system, refer
to Section 3.6 for additional troubleshooting information
on diagnosing failures.

1.3.2 Engine Air System
The air cleaner (Figure 1-1) is designed to prolong
engine life and performance by preventing dirt and grit
from entering the engine and causing excessive wear
on all operating parts. In order for the air filter to operate
properly, the operator must regularly maintain the air
cleaner equipment in accordance with the instructions
provided within this document.
1.3.3 Fuel System
The fuel system is fitted with an in−line fuel strainer and
a fuel filter, which also acts as a water separator. The
fuel system is shown in Figure 1-4.
There are two fuel heating / warming options:
The fuel heater system is located in the fuel filter, and
uses a 12 volt heater to heat fuel as it passes through the
fuel filter, see Figure 1-2.
The fuel warming system is a mechanical system that
warms fuel by passing it through a heat exchanger that
is warmed with engine coolant, see Figure 1-1.
