ENGINE AFTER SERVICE
Please feel free to contact your dealer for periodical inspection and
maintenance.
Doosan Genuine Parts
Genuine Doosan parts are identical with those used in the engine
production, and accordingly, they are warranted by Doosan.
Please ensure that only genuine Doosan parts, lubricants and fluids
are used for service and/or repair.
DIESEL PARTICULATE AFTERTREATMENT
The diesel particulate aftertreatment assembly has important informa-
tion for service and replacement stamped into the canister. There are
three important stamping locations on the aftertreatment assembly:
1. Aftertreatment diesel oxidation inlet/catalyst part number and serial
number, located on the inlet/catalyst section.
2. Aftertreatment diesel particulate filter part number and serial
number, located on the filter section.
3. Aftertreatment assembly and outlet section part number, located on
the outlet of the aftertreatment system.
A typical aftertreatment information stamping can provide the following:
1. Section name
2. Part number
3. Date code
4. Assembly number (
only
located on the outlet section)
5. Serial number
VARIABLE GEOMETRY TURBOCHARGER
The Holset® variable geometry turbocharger (VGT) dataplate is
located on the turbocharger inlet compressor housing. The dataplate
contains the following information which will assist in service or
replacement.
•
Cummins® assembly part number
•
Serial number
•
Customer number
•
Model number.
ELECTROMAGNETIC INTERFERENCE (EMI)
General Information
Some engine applications utilise accessories (CB radios, mobile
transmitters, etc.) that generate and use radio frequency energy that,
if
not
installed and used properly, can cause electromagnetic
interference (EMI) conditions to exist between the accessory and
Cummins electronic controlled fuel system. Cummins is
not
liable for
any performance problems with either the fuel system or the accessory
due to EMI. EMI is
not
considered by Cummins to be an engine failure
and therefore is
not
warrantable.
System EMI Susceptibility
Your Cummins product has been designed and tested for minimum
sensitivity to incoming electromagnetic energy.
Testing has shown that there is no engine performance degradation at
relatively high energy levels; however, if very high energy levels are
encountered, then some noncritical diagnostic fault code logging can
occur. The fuel system EMI susceptibility level will protect your engine
from most, if
not
all, electromagnetic energy-emitting devices that
meet the Federal Communications Commission legal requirements.
System EMI Radiation Levels
Your Cummins product has been designed to emit minimum
electromagnetic energy. Electronic components are required to pass
various Cummins and industry EMI specifications. Testing has shown
that when the engine is properly installed, it will not interfere with
onboard communication equipment or with the vehicle's, equipment's,
or vessel's ability to meet any applicable EMI standards and regulated
specifications.
If an interference condition is observed, follow the suggestions below
to reduce the amount of interference:
1. Locate the receiving antenna as far away from the engine and as
high as possible.
2. Locate the receiving antenna as far away as possible from all metal
obstructions (e.g., exhaust stacks)
NOTE:
The electronic actuator on the VGT is a serviceable
component and has a separate dataplate that assists in service or
replacement.
