Shelf No: CE-146 // ID-11.16382; What is EGR, what does the gear do?: EGR (exhaust gas recirculation) is a system in internal combustion engines that recirculates a portion of the exhaust gases back into the intake manifold. This system is generally used to control and reduce nitrous oxide (NOx) emissions. Exhaust gases contain nitrogen oxides due to the high temperatures and pressures in internal combustion engines, which can be a source of environmental pollution. The EGR system takes the exhaust gases, cleans them, and then returns these cleaned gases to the intake manifold. This reduces the temperature in the combustion chamber, thereby reducing the formation of nitrogen oxides in internal combustion engines. This can help the engine run more efficiently, increase fuel efficiency, and reduce emissions. The EGR gear is a part that controls and directs this system. Gears are used to regulate the exhaust gas recirculation rate and optimize system performance.
