ENGINE
Description
The engine is a Cummins QSB6.7 (Figure 7-1) Tier 3 or Tier
4i diesel engine. This Service Manual does not include
detailed information on the engine itself. A separate manual
as prepared in detail by the engine manufacturer, is supplied
with this Service Manual. However, a short description and
maintenance of certain components of the fuel system, air
intake system, and water cooling system is provided in this
section.
The engine is electronically controlled by the Electronic
Control Module (ECM), it is the control center of the system.
It processes all of the inputs and sends commands to the fuel
systems as well as vehicle and engine control devices.
Engine speed is controlled by the foot throttle pedal in the
cab. It controls engine RPM which increases or decreases
proportionately with the amount of foot pressure applied to
the pedal. The foot throttle pedal is electrically connected to
the superstructure control module which sends the signal to
the engine ECM via the J1939 data link.
The engine and its components are enclosed in a hood
assembly with a grill in the rear of the hood for adequate air
circulation. Access to the engine is gained through a door
assembly in the right side of the hood.
The air intake filter is mounted on the rear of the left rear
fender. The muffler is mounted on the left side of the hood
behind the rear fender.
To aid in starting the engine in cold weather, the engine is
equipped with electric air heating elements that are located
in the engine’s intake air stream to aid in cold starting and
reduce white smoke at start-up. In the preheat mode, the
engine should not be cranked until the WAIT-TO-START
lamp turns off. The WAIT-TO-START lamp is illuminated
during the preheat time that takes place when the ignition
switch is in the ON position during cold weather starting. The
ECM checks intake manifold temperature to determine how
long to energize the air heater before extinguishing the
WAIT-TO-START lamp. Once the engine is started, the
electric air heating element will be energized again for a time
period determined by intake air temperature.
DANGER
Do not spray starting fluid into the air inlet. The spray will
contact the heater elements and could explode causing
personal injury.
