The Cummins 6.7-liter engine was first introduced to the market in March, 2006 with Ram's announcement that they were reentering the chassis cab market with their 3500 chassis cab truck. The 3500 chassis cab was given a model year 2007 nomenclature (TDR Issue 52, page 118.) The 4500/5500 chassis cab trucks were introduced later (February, 2009). <br/><br/>Then on January 1, 2007 Ram and Cummins introduced the 6.7-liter engine to the consumer 2500/3500 market. The January introduction coincided with new emissions legislation and all Ram consumer 2500/3500 trucks made after January 1, 2007 are known as '07.5 vehicles (a mid-year produce change). Credit goes to Ram and Cummins: With the '07.5 6.7-liter engine, they were one step ahead of the competition. Not only did the engine meet the 2007 emission requirements, it also met the future 2010 requirements. <br/><br/>Over the past two years, the 6.7-liter engine has had its share of teething problems, mostly software and engine calibration updates (flashes). I am pleased to report that warranty problems on the 6.7-liter are now lower than those of the final year of the 5.9-liter engine that was used from model years '03 - '07. Additional good news about the 6.7-liter engine: In April of 2008, Cummins announced that it had earned the Automotive News PACE (Premier Automotive Supplier's Contribution to Excellence) Award for the 6.7-liter engine (Issue 61, page 48). <br/><br/>And now, the point of all this rambling. Folks still do not understand the 6.7-liter engine and all of its exhaust aftermarket controls and devices. Perhaps rightfully so. The system seems complicated, but really it is not too difficult to understand. For grins, <a href="https://www.turbodieselregister.com/articlelive/content_images/TDR69_Emissions.pdf" target="_blank">here is a TDR chapter and verse article that will bring the new or prospective owner up to date (Issue 69, pages 48 - 53)</a>. <br/><br/>Likewise, in late 2007 the folks at Cummins worked with long-time TDR Writer and television guy, Sam Memmolo, to develop a video to explain the exhaust after treatment controls. For those of you who would like to take the vide route, here it is.<br/></p>

<p><br/>Thank you for viewing this video or reading the TDR. We hope we have entertained and educated. <br/><br/>By the way, if you missed my "take away," I will give you my conclusion. <u><em>Ram and Cummins have developed a solid engine with a proven after treatment system.</em></u> After five years in the market, how does the Ram compare to the competition? Well, just try a simple web search on 2010 Power Stroke engine or 2010 Duramax engine. </p></body></body>[/RAW]
