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.
