It is well known that a high-pressure fuel injection is effective for the reduction in particulates and smoke emissions. Exhaust gas recirculation (EGR) is effective for the reduction in NOx emission.

ABSTRACT Future emissions standards for passenger cars require a reduction of NO ₓ (nitrogen oxide) and CO ₂ (carbon dioxide) emissions of Diesel engines. One of the ways to reach this challenge while ...

Despite sounding like a thoroughly entertaining evening out, it is actually a description for one of the most important processes in the majority of engines. Known as the four-cycle, it is the process ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen environmental ...

The diesel engine was one of the most ambitious engineering undertakings in history. It was so radical and high-minded that it still hasn’t been totally perfected—even after 150 years of development.

Diesel engines are the perfect recipients of mild engine modifications. They are considerably robust—generally much more so than gasoline engines. Without going into a diesel history lesson, this is ...
