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 ...

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 ...

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 ...

In this study three EGR methods were applied to a 12 liter turbocharged and intercooled DI diesel engine, and the exhaust emission and fuel consumption characteristics were compared. One method is the ...
