On-Board Diagnostics is a proven system with nothing to be concerned about from a maintenance standpoint. The same holds true for SCR and the aftertreatment technology that every major diesel engine manufacturer is using to meet existing 2013 emissions standards and the 2014 regulations being implemented by the EPA on GHG emissions and the U.S. Department of Transportation (DOT) on fuel efficiency.
Cummins ISX15 was the first engine certified to meet these new standards - a year ahead of schedule, getting approval in October 2012. It is a good example of how a totally integrated approach can yield significant benefits.
Through a series of related improvements, Cummins has been able to reduce parasitic loads and limit the number of active aftertreatment regeneration events. Plus, the ISX15 is capable of downspeeding – all of which yields a fuel economy gain of up to 2 percent.
This, in turn, has reduced the GHG output of the engine without compromising performance, reliability or durability.
The fact that Cummins is able to optimize proven technologies and meet clean-air standards a year ahead of schedule – reducing operating costs with no downside risk – is proof of how forward-thinking, integrated systems and planning are keeping the trucking industry – and everyone who depends on it – a step ahead.
