Engine Type and Aftertreatment Type
There are four different engine types and two
different types of aftertreatment systems.
• JR 854E-E34TA is a turbocharged, charge
cooled engine, with a wall flow Diesel Particulate
Filter (DPF).
• JS 854F-E34T is a turbocharged engine
with a wall flow DPF
• JT 854F-E34T is a turbocharged engine
with a through-flow DPF
• JV 854F-E34TA is a turbocharged, charge
cooled engine with a wall flow DPF
The JV model 854F-E34TA is a constant power
output engine, rated at 2200 RPM.
The through-flow aftertreatment system DPF will not
require a service period.
The wall flow aftertreatment system DPF will require
a service period. For more information refer to this
“Operation and Maintenance Manual”Maintenance
Interval Schedule.
Electronic Engine Features
The engine operating conditions are monitored. The
Electronic Control Module (ECM) controls the
response of the engine to these conditions and to the
demands of the operator. These conditions and
operator demands determine the precise control of
fuel injection by the ECM. The electronic engine
control system provides the following features:
• Engine monitoring
• Engine speed governing
• Control of the injection pressure
• Cold start strategy
• Automatic air/fuel ratio control
• Torque rise shaping
• Injection timing control
• System diagnostics
• Aftertreatment Regeneration
For more information on electronic engine features,
refer to the Operation and Maintenance Manual,
“Features and Controls” topic (Operation Section).
Engine Diagnostics
The engine has built-in diagnostics to ensure that the
engine systems are functioning correctly. The
operator will be alerted to the condition by a “Stop or
Warning” lamp. Under certain conditions, the engine
horsepower and the vehicle speed may be limited.
The electronic service tool may be used to display
the diagnostic codes.
There are three types of diagnostic codes: active,
logged, and event.
Most of the diagnostic codes are logged and stored in
the ECM. For additional information, refer to the
Operation and Maintenance Manual, “Engine
Diagnostics” topic (Operation Section).
