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 ...

Your engine’s manifold absolute pressure (MAP) sensor is your little buddy. Buried somewhere in the stream of your charged intake air (usually in the manifold), it employs a little ceramic or silicone ...

Exhaust systems are designed to survive years of heat, vibration, and road grime, yet some of their most important parts deteriorate so gradually that drivers rarely notice until performance or safety ...

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 ...
