Modern internal combustion engines — including those that run on diesel fuel — require a lot of special parts and systems to prevent dumping excess emissions into the atmosphere. Not only are those ...

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 ...

Cooled-EGR (Exhaust Gas Recirculation) systems have been used since October 2002 by five major engine manufacturers (Cummins, Detroit Diesel, International, Mack and Volvo) to reduce emissions of smog ...

Low pressure Exhaust Gas Re-circulation (EGR) can be used along with Diesel Particulate Filter (DPF) systems to reduce NOx emissions from heavy-duty diesel engines. Normally the use of EGR decreases ...

Diesel has had a rough go of it during the last few years, but an increasingly commonplace technology is working to change the fuel's image and make diesel vehicles viable for the future. Kyle Hyatt ...

Manufacturers are busy rolling out solutions to meet Final Tier 4 off-road requirements for diesel engine exhaust emissions, and the technologies look very familiar to those already in use in the ...

Volvo Trucks is widening its engine range with the launch of a D13 engine featuring EGR exhaust gas recirculation. The engine is available in four power output levels and is certified for current ...
