According to the Diesel Technology Forum, 53% of all commercial diesel trucks are equipped with the newest generation, clean diesel engine. Those engines deploy emission-strangling equipment that has been standard in commercial trucks on the road since 2010, which help achieve a more than 98% reduction in nitrogen oxides (NOx) and particulate matter.

Joining Jason and Matt this week on CCJ's 10-44 is Diesel Technology Forum Executive Director Allen Schaeffer, and the trio discusses what lies ahead for the diesel engine as emissions regulations get tighter and tighter, and Schaeffer argues that as cleaner-burning engines get more expensive, fleets are more likely to hang on to older equipment.
