WebIn internal combustion engines, exhaust gas recirculation ( EGR) is a nitrogen oxide ( NO x) emissions reduction technique used in petrol/gasoline, diesel engines and some hydrogen engines. [1] EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. WebHigh-pressure EGR is taken before the turbo and passed through a cooler and valve to the intake manifold. Pressure balance is important. Low-pressure EGR is taken after the turbo (and usually after the aftertreatment system) and added to the intake air preturbo. A pump and exhaust gas cooler are usually employed. simply nature\u0027s promise phone number
