Exhaust gas recirculation is a technique used to reduce nitrogen oxide emissions in both petrol and diesel engines. These 'EGR' systems are used in conjunction with other emissions control devices, ...

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 ...

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 ...

The control of nitrogen oxides by exhaust recirculation has been evaluated theoretically by digital computer simulation of the engine cycle. Nitric oxide emission, power output, and fuel consumption ...

SAE International Journal of Engines, Vol. 9, No. 4 (December 2016), pp. 2477-2492 (16 pages) ABSTRACT Small natural gas cogeneration engines frequently operate with lean mixture and late ignition ...
