Heavy Duty Diesel

Exhaust emissions from heavy-duty diesel engines have been legislated since the 1960’s and continue until 2010. Smoke emissions continue to be controlled but exhaust odor regulations were never promulgated. Gaseous emissions (oxides of nitrogen, carbon monoxide, hydrocarbons) were not regulated until 1973 and particulate matter first regulated in 1988. Emission regulations have been through several periods of cooperation between regulators and manufacturers but there have also been periods of conflict and lawsuits. The most recent issues are with the October 2002 requirements of the Consent Decrees signed by seven diesel engine manufacturers and USEPA/US DOJ/CARB. Also the 2007/2010 regulations are under review.

Heavy Duty Diesel

A considerable amount of work was carried out in the mid-1980s to develop heavy-duty diesel engines that could meet limits on particulate emissions. These limits, although high by today’s standards, were considered very restrictive. Some manufacturers struggled to achieve the 0.6 g/bhp-h particulate matter limit with enough margin for production variabilities and to account for the deterioration factor. Significant progress was achieved in diesel emissions control through engine and fuel system design changes. This eventually made it possible to meet a particulate level of 0.25 g/bhp-h for 1991. The next target level for particulate emissions is 0.1 g/bhp-h for the 1994 heavy-duty engine. To meet the challenge, engine developers are not only considering engine and injection system design changes but also fuel improvements and exhaust aftertreatment. This paper includes a review of past and current strategies used to control emissions in the modern diesel engine.
