About 1/3 of Class 3-8 trucks in US equipped with advanced cleaner diesel engines
03 July 2014
About one-third of all medium- and heavy-duty commercial trucks registered in the United States (2.9 million of 8.8 million trucks)—are now equipped with newer technology clean diesel engines, according to data compiled by IHS Automotive for the Diesel Technology Forum (DTF).
The data includes total registration information on Class 3-8 trucks from 2007 through 2013 in all 50 states and the District of Columbia. Beginning in 2007, all heavy duty diesel trucks sold had to meet particulate emissions levels of no more than 0.01 grams per brake horse-power hour (g/bhp-hr).

Texas, California and Indiana have the most overall number of clean diesel trucks, as well as the highest number of post-2010 diesel trucks (although California and Indiana swap positions); beginning with the 2010 model year, 100% of the new on-road heavy-duty diesel engines were required to meet the EPA’s stringent NOx standards.

I have always believed that the Cash for Clunkers program was a waste of money and ineffective for cars. The case for heavy trucks is completely different. Diesel exhaust is a major cause of both Cancer and Heart Disease. In 2007 diesel emission regulation changed to dramatically reduce the harmful emissions from new trucks. While having 30% of the trucks meet the new standard is a good thing, when it come to our health, it just is not good enough. Since these are commercial vehicles, the only way to get the polluters off the road is through economics. Lets have a Cash for Clunkers program for heavy trucks.

Clean Coal Clean Blue NG and now Clean Diesel?

Richard, CfC was aimed at moving auto dealer inventory, not reducing pollution or fuel consumption. Had we been sensible about it, we would have warehoused all the gas-guzzling vehicles on dealer lots, halted production and trickled them out over the next several years at a steep premium while using gas taxes and feebates to get the citizens to actually pay attention to fuel consumption.

And speaking of clean vehicles, what are the particulate emissions of the natural-gas engines now making inroads into the heavy truck fleet? Since NA has a surplus of NG at the moment, we'd be far better off switching trucks to use it than trying to filter the exhaust of engines that are inherently much dirtier.
