Numerous benefits have been claimed for low pressure EGR. For example there is more energy available to the turbine to power the compressor, so higher EGR rates may be attained compared to high pressure EGR [5]. flixborough disaster lessons learnedIn internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. The exhaust gas displaces atmospheric air and reduces O2 in the combustion chamber.
