The Log
6 February 2010: Updated summary of European diesel fuel specifications covers the changes brought by Directive 2009/30/EC and the EN 590:2009 standard.
3 February 2010: Updated Technology Guide paper on compatibility of biodiesel with petroleum diesel engines [announcement | paper]
26 January 2010: The US Environmental Protection Agency adopted a new national air quality standard for nitrogen dioxide to control short-term NO2 exposures and introduced new NO2 monitoring requirements for urban areas [more ...]
25 January 2010: Emission standards: Updated summary of European CO2 emission regulations for light-duty vehicles.
13 January 2010: The Health Effects Institute published a comprehensive review of the worldwide traffic emissions and health science, concluding that there are substantial gaps in what we know about exposure to traffic air pollutants and their health effects [more ...]
Updated Technology Guide paper on fuel injection systems for heavy-duty engines [announcement | paper]
12 January 2010: US DOE announces $187 million in grants to improve vehicle fuel efficiency for heavy-duty trucks and passenger cars [more ...]
5 January 2010: A new report by the Pew Center on Global Climate Change concludes that by 2050, reductions of GHG emissions of more than 50% below business-as-usual levels are possible from global aviation, and of more than 60% from global marine shipping.
Bosch announced it will invest $423 million in India between 2010 and 2012, mostly in diesel systems [more ...]
28 December 2009: Updated summary of US marine engine emission standards reflects the provisions of the recent Category 3 engine rule.
22 December 2009: The US EPA adopts final Tier 2 and Tier 3 emission standards for large, Category 3 marine engines [more ...]
16 December 2009: With two new papers on engine lubricating oil consumption, our Technology Guide coverage of lube oil topics seems to be complete.
7 December 2009: The total US greenhouse gas emissions in 2008 were 2.2% below the 2007 level, according to the new report by the US EIA, Emissions of Greenhouse Gases in the United States 2008. The decrease was caused by a drop in petroleum consumption and a lower energy demand for the year in most sectors of the economy.
US EPA signed the final endangerment finding for greenhouse gases [more ...]
26 November 2009: Added new Technology Guide paper on the measurement methods of engine lubricating oil consumption [announcement | paper]
Diesel Engine & Emissions
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. In Europe, diesel powered cars have been increasingly popular. The diesel engine is a major candidate to become the power plant of the future. Before that happens, however, further progress in diesel emission control is needed.
Internal combustion engines are significant contributors to air pollution, which has a damaging impact on our health and the environment and is suspected to cause global climate changes. Environmental benefits of diesels, such as low greenhouse gas emissions, are balanced by growing concerns with emission of nitrogen oxides and diesel particulates. Increasingly tighter environmental regulations worldwide call for advanced emission controls and near-zero diesel emission levels in the years to come.
DieselNet, the only information service exclusively devoted to engines and emissions, is the internet forum for the exchange of technical and business information on engines, emissions, emission control, and all related issues which, hopefully, will contribute to the development of the clean diesel engine of the future.
