High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more. HPCR fuel ...

Increasingly stringent diesel engine exhaust emissions regulations have, over the past 20 years, reduced output of nitrogen oxides (NOx) by 95% and particulate emissions by 90% in heavy trucks. These ...

Among internal combustion engines, diesel engines boast excellent thermal efficiency and can burn fuel that is not highly refined. They use a compression ignition system in which intake air is ...

Most diesel engines in the U.S. use a combination of technologies to reduce emissions. Usually there will be a diesel particulate filter (DPF), selective catalytic reduction (SCR) with urea (DEF fluid ...

Jacobs Vehicle Systems has introduced Active Decompression Technology (ADT), which the company says enables heavy-duty commercial vehicles to benefit from an engine stop-start system and eliminating ...

The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...

The air filter setup on most diesels is the same as on gasoline-powered vehicles, with the filter located inside the cold air collector box located under the hood. You have to take one big precaution ...

UNSW researchers have prototyped and tested a retrofit system that converts diesel engines to run on 90% hydrogen, radically reducing both carbon dioxide and nitrous oxide emissions while boosting ...

When you cut to the basic principles of heavy-duty trucks it comes down to return on investment: maximum mpg, meeting emissions requirements and the truck running at optimum conditions and ...

Diesels require more stored energy for starting than gasoline vehicles do, especially on cold days. Instead of just using the battery to enable the starter to crank ...

For the PDF version of this article, click here. Diesel-powered cars accounted for only 3.2% of the 2005 U.S. light vehicle sales, but J.D. Powers forecasts growth to 9% in 2012. Diesels already ...
