A team from the US National Renewable Energy Laboratory and the Colorado School of Mines has measured gas phase and particle-associated non-regulated pollutant emissions from a heavy-duty engine operating both with and without a catalyzed DPF and operating on biodiesel fuel. Experiments were conducted on a 2002 model year 5.9

These new SIPs demonstrate that, by 2024, pollution will be reduced to the level needed to attain the 1997 8-hour ozone standard of 0.08 ppm by 2024, NO x will have to be reduced by 75% and VOCs by 25% from 2002 levels. ppm by 2024, NO x will have to be reduced by 90% and VOCs by 52% from 2002 levels. For the SJV to attain 0.08

Maritime traffic on the world’s oceans has increased four-fold over the past 20 years, likely causing more water, air and noise pollution on the open seas, according to a new study quantifying global ship traffic. The number of ships traversing the oceans grew by 60% between 1992 and 2002.

The program is geared to help small California-based fleets replace their older, polluting trucks with newer, cleaner models. Approximately $28 million is available through the program to fund truck replacements or exhaust retrofits statewide. VIP is part of the state’s overall plan to cut toxic diesel emissions 85 percent by 2020.

CO 2 and NO x certification test data for heavy-duty diesel engines certified from 2002 through 2019. Source of data: US EPA (2019). Chart: MECA. A wide variety of technology options can be deployed on heavy-duty engines and vehicles to reduce engine-out NO x while improving fuel economy to reduce the total cost of ownership of trucks.
