The Log

29 April 2016: A summary of technical sessions on engine and vehicle emissions at the SAE Congress held on April 12-14 in Detroit [more ...]

26 April 2016: Updated Technology Guide paper on NOx Adsorbers includes more information on passive NOx adsorber (PNA) technology.

21 April 2016: Updated summary of EU emission standards for light-duty vehicles includes more details on RDE testing requirements.

20 April 2016: US Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) has announced $30 million in funding for the NEXT-Generation Energy Technologies for Connected and Automated on-Road vehicles (NEXTCAR). The NEXCAR program seeks to fund the development of new and emerging vehicle dynamic and powertrain (VD&PT) control technologies that can reduce the energy consumption of future vehicles through the use of connectivity and vehicle automation. Potential vehicle energy improvement technologies may include advanced technologies and concepts relating to full vehicle dynamic control, powertrain control, improved vehicle and powertrain operation through the automation of vehicle dynamics control functions, and improved control and optimization facilitated by connectivity.

Diesel Engine & Emissions

The diesel engine is the most efficient power plant among all known types of internal combustion engines. Heavy trucks, urban buses, and industrial equipment are powered almost exclusively by diesel engines all over the world and diesel powered passenger cars are increasingly popular. For the foreseeable future, the world’s transportation needs will continue to rely on the diesel engine and its gasoline counterpart. However, both engine technologies are evolving at an ever increasing pace to meet two major challenges: lower emissions and increased energy efficiency.

Internal combustion engines are significant contributors to air pollution that can be harmful to human health and the environment. In response, clean diesel technologies with near-zero emissions of NOx and PM have been developed and introduced in regions with the most stringent emission standards: North America, Europe and Japan. While new clean diesel engines are gradually replacing the population of older diesel engines in these regions, older engines already in service are being retrofitted with clean diesel technologies to hasten emissions reductions. As this trend spreads to other parts of the world, the environmental focus has shifted to climate changing emissions and energy efficiency. The environmental benefit of low greenhouse gas emissions, traditionally associated with the diesel engine, is no longer sufficient. To meet future greenhouse gas and fuel economy regulations, new technologies are being developed—low temperature combustion, waste heat recovery, powertrain electrification, to name a few—that further increase the efficiency not only of the diesel engine powertrain but the entire vehicle as well. Under low-carbon regulatory policies, the scope for potential improvements is no longer limited to engines and vehicles, but also includes life cycle effects of fuel production and vehicle manufacture.

DieselNet, the only information service exclusively devoted to diesel engines and emissions, is an internet forum for the exchange of technical and business information on diesel engines, fuels, emissions and many of the important technologies required by the clean and efficient diesel engines of the future.
