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 ...

There are times in life when we must endure that which is unpleasant for the greater good of all. And while it may not be high on that list for some, vehicle emissions equipment has certainly become ...

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 ...

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 ...

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 ...

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 ...

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 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 ...

• 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 ...
