Noise and Emissions Requirements
2010 Automotive engines have been tested and EPA/CARB certified with a complex inte
-
grated system. This system is comprised of several emissions control devices including,
but not limited to, a Diesel Particulate filter (DPF) and a Selective Catalyst Reduction (SCR)
system.
The body builder must not modify or relocate any devices included in the emissions
system. Doing so may result in the voiding of all warranties and the occurrence of an
emissions noncompliance event that may be considered tampering and punishable by the
assessment of penalties by the EPA and ARB as well as the need for remedial measures.
Modification of the emissions system can only be done with the preapproval of Cummins
and/or Kenworth. Body builders’ first point of contact concerning emissions systems
modifications will be Kenworth.
It is possible to relocate the DEF tank, however the relocation requirements need to be followed. Any variance from the
relocation requirements may cause the emissions control components/systems to operate improperly potentially resulting
in engine de-rate . See page 4-3 for relocation requirements .
Some 2010 engine emissions certified vehicles will be equipped with an On-Board Diagnostics
(OBD) system. The OBD system is designed to detect malfunctions of any engine or vehicle
component that may increase exhaust emissions or interfere with the proper performance of the
OBD system itself .
The OBD system consists of computer program on one or more of the vehicle’s Electronic Control
Units (ECUs) . This program uses information from the control system and from additional sensors
to detect malfunctions . When a malfunction is detected, information is stored in the ECU(s) for
diagnostic purposes . A Malfunction Indicator Light (MIL) is illuminated in the dash to alert the
driver of the need for service of an emission-related component or system.
To ensure compliance to emissions regulations, the final configuration of certain features of the completed vehicle
must meet specific requirements. This section describes requirements relevant for only the most common or critical
modifications done by body builders. For a complete description of acceptable modifications, see the application
guidance available from the manufacturer of the engine installed in the chassis.
