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 ...

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 ...

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 ...

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 ...

An increasing proportion of the Danish vehicle fleet consists of diesel vehicles. In urban areas diesel vehicles are causing air pollution (from carbon particles, nitrogen oxides (NOX)) and unburned ...

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 ...

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 ...

The first Diesel engines were started 130 years ago, but they have moved a long way since then. Like their gasoline counterparts, the compression ignited engines have evolved from the rough units of ...

The 2007 model year ushers in a new era of diesel engine technology. The previously established image of diesel engines as noisy and dirty will be radically altered as new NOx and particulate ...

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 ...

The U.S. Environmental Protection Agency is a product of the Clean Air Act, which requires the agency to monitor air quality and eliminate threats to human health. Two major components of diesel ...
