EGR stands for exhaust gas recirculation and is used in gasoline and diesel engines. In internal combustion engines, EGR is a technique used to reduce nitrogen oxide(NOx) emissions. It works by recirculating a portion of an engine's exhaust gas back to the engine's intake. This process keeps the engine cool while maintaining good fuel efficiency. Of course, it also reduces emissions-thereby keeping in tandem with the law.
