Exhaust gas recirculation (EGR) coolers are critical components in modern diesel engines, designed to mitigate nitrogen oxide emissions while preserving engine efficiency. However, their performance ...

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 ...

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 ...

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 ...

Controlling vehicle emissions in modern vehicles involves more than just bolting up a catalytic converter and calling it a day. There are other components that effectively, and intuitively, cut out ...

Komatsu's strategy to meet EPA's 2006 deadline for Tier 3 diesel exhaust emissions promises to improve fuel efficiency up to 15 percent. The combustion chamber design is expected to bring the ...

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 ...

Your engine’s manifold absolute pressure (MAP) sensor is your little buddy. Buried somewhere in the stream of your charged intake air (usually in the manifold), it employs a little ceramic or silicone ...

EGR stands for exhaust gas recirculation, and the EGR valve is part of a system that does as the name implies: recirculate exhaust gas back into the engine’s intake manifold for a return trip to the ...

• New diesel-emissions regulations for off-road equipment took effect in January. • All engine manufacturers are tuning incylinder combustion to minimize emissions. • Where exhaust aftertreatment is ...
