Diesel Retrofit Basics

Presentations given during a panel discussion ("Diesel Engine Retrofit 101") organized by MECA at the September 18-21, 2006 Pacific Oil Conference and Tradeshow in Reno, NV provide basic information on important topics associated with applying diesel retrofit emission controls to existing vehicles and/or equipment. These five presentations are highlighted below and are available as a resource for interested potential end-users.

1. Retrofitting Emission Controls for On-Road Diesel Engines (PDF 988 KB)
   This presentation provides a broad overview of existing retofit technology options and emerging retrofit technologies for controlling particulate matter and NOx emissions from in-use diesel engines.
2. Retrofit Application Engineering (PDF 300 KB)
   This presentation describes the important steps associated with selecting a retrofit technology for a specific on-road or off-road diesel engine application, including defining the engine/vehicle/existing exhaust system and the application's duty cycle/in-use exhaust temperature profile.
3. Installation of Retrofit Devices (PDF 1,230 KB)
   This presentation provides examples of acceptable installation practices for diesel oxidation catalysts and diesel particulate filters.
4. Diesel Particulate Filter Maintenance (PDF 110 KB)
   This presentation focuses on diesel particulate filter cleaning procedures associated with the periodic removal of inorganic ash materials from filters. Other maintenance-related procedures for common retrofit technologies are also listed.
5. On-Vehicle Monitors Used in Retrofit Applications (PDF 428 KB)
   This presentation highlights the features and capabilities of on-board monitor systems that are typically provided with retrofit technologies. These monitors typically provide the end-user with diagnostic and data-logging information.
