Engine Optional Features - Navistar MaxxForce DT 9 Operation And Maintenance Manual

Engine Optional Features

Air Compressor
An air compressor is available for applications that require air
brakes or air suspension. A hydraulic power steering pump can
be used with or without the air compressor.
Coolant Heater
A coolant heater is available to raise the temperature of the
coolant surrounding the cylinders for improved performance
during cold weather startups.
Cruise Control
The ECM controls the cruise control feature. The cruise control
system functions similarly for all electronic engines. Maximum
and minimum allowable cruise control speeds will vary based on
application. To operate cruise control, see appropriate Vehicle
Operator's Manual.
Engine Brake
An optional exhaust or engine brake is available to aid in the
deceleration rate of vehicles. The exhaust and engine brake
provides improved braking performance. These options are
mutually exclusive and are available for all ratings.
Engine Fan Control
The engine fan control commands higher air flow through the
radiator when the Air Conditioner (A/C) is on or when the coolant
or inlet air temperature goes above a set temperature.
SECTION 1 – ENGINE SYSTEMS
Engine Warning Protection System (EWPS)
EWPS is designed to protect the engine from damage
by monitoring critical engine data such as engine speed,
temperature, oil pressure and coolant levels. This feature will
alert the operator by using a combination of visual and audible
warnings when critical engine parameters have been exceeded.
For further information see Engine Warning Protection System
EWPS (page 56).
Fuel Heater
A fuel heater is available and installed in the fuel filter assembly.
The heater warms the supply fuel to prevent waxing during cold
conditions.
Idle Shutdown Timer (IST) Federal - Optional or California -
Standard
IST allows the ECM to shut down the engine during extended
engine idle times.
Beginning with the 2008 Model Year engine, all MaxxForce®
engines certified for sale in the state of California will conform
to mandatory California Air Resources Board (CARB) Engine
Shutdown System (ESS) regulations.
All (non-California) Federal MaxxForce® engines can have idle
time that can be programmed from 2 to 120 minutes.
For further information, see Engine Shutdown (page 52).
