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 in-depth video, we explore the EGR (Exhaust Gas Recirculation) system, detailing its history and evolution, operating ...

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 ...

A new study shows promising results for the use of GE Vernova’s exhaust gas recirculation (EGR) systems to reduce the cost of carbon capture systems. The U.S. Department of Energy’s (DOE) Office of ...

You're driving down the road and having a normal day behind the wheel of your car. You look down on the dashboard to check your gauges and speed, but you notice that a little orange "Check Engine" ...

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, ...

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 ...

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 has been adopted by a number of engine manufacturers as the most effective technology to meet Tier III emission requirements with least impact on fuel economy. A portion (max 10%) of exhaust gas ...
