    Application Standard

    Subject This document is for the following applications:

    2013 US EPA Aftertreatment Controls Application Standard

    Automotive Industrial Marine G-Drive Genset Filtration Emissions Solution

    Date: November 10th, 2015 Document Number AS351.01

    Engine Models included: 2013 EPA Heavy Duty & Medium Duty Automotive

    Author: Ragibul Huq(ML305) Page 1 of 31

    This Application Standard outlines the main Aftertreatment System components and the known Cummins Emission Solutions requirements for application in on-highway truck and bus. This document contains information that Cummins Emission Solutions has learned during development to date. Revisions to this document are anticipated as experience is gained. This document should be used by the OEM to assist in vehicle design but is not a substitute for validation of individual vehicle applications of the Aftertreatment System.

    On Board Diagnostics (OBD) Requirements HD OBD The following components are HD OBD regulated. The OEM supplied OBD components are the responsibility of the OEM to implement and install according to the HD OBD Requirements specified in this document.

    1. General Information

    1.1 Purpose

    The purpose of this document is to provide application guidelines for integrating the Aftertreatment systems including Diesel Particulate Filter (DPF), Selective Catalytic Reduction (SCR) and sensors with the CES, Aftertreatment Control Module (ACM). These guidelines focus on SCR control system requirements for proper system operation, engine diagnostic operation, and compliance with 2013 EPA regulations specific to Engine type. Additional information related to the mechanical installation of the SCR aftertreatment system may be found in 2013 US EPA Aftertreatment Mechanical Installation Requirements.

    2. Installation Requirements

    Because of the complex nature of this installation guideline, the installation requirements will be singled out using bold text MUST for clarity throughout the document. In other words, the use of the term MUST denotes a requirement that must be followed for obtaining CES concurrence for an approved installation of the Aftertreatment system. Aftertreatment Control Module (ACM)

    1. The ACM MUST NOT be exposed to temperatures outside the operating range -40 C and +105 C.

    2. The ACM MUST be mounted in where it meets IP6K9K requirement according to ISO 20653 standard.

    3. The ACM case MUST NOT be in contact with the vehicle chassis ground such that a differential voltage of more than 0.5 volts exists between case and Vbatt (-).

    4. The OEM harness MUST be secured to a point at the same vibration level as the connection between the two in order to reduce relative motion between the mating connectors and reduce fretting corrosion.

    5. The OEM harness MUST be properly supported so that it does not induce excessive tension on the extension connector or the ACM con
