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 Exhaust Gas Recirculation (EGR) valve sends some of the exhaust gas back into the cylinders to reduce combustion temperature. This is required because nitrous oxides (nasty pollutants) form when ...

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 ...

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 ...

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 ...
