In 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 … See more The first EGR systems were crude; some were as simple as an orifice jet between the exhaust and intake tracts which admitted exhaust to the intake tract whenever the engine was running. Difficult starting, rough idling, … See more Because diesel engines depend on the heat of compression to ignite their fuel, they are fundamentally different from spark-ignited engines. The physical process of diesel-fuel combustion is such that the most complete combustion occurs at the highest … See more • Heywood, John B., "Internal Combustion Engine Fundamentals," McGraw Hill, 1988. • van Basshuysen, Richard, and Schäfer, Fred, "Internal Combustion Engine Handbook," SAE International, 2004. See more The exhaust gas contains water vapor and carbon dioxide which both have lower heat capacity ratio than air. Adding exhaust gas therefore reduces pressure and temperature during the isentropic compression in the cylinder, thereby lowering the See more • Diesel exhaust • Secondary air injection See more • Lecture notes on improving fuel efficiency that discusses the effects of specific heat ratio, University of Washington • Diesel cycle calculator that can be used to show the effect of specific heat ratio, Georgia State University HyperPhysics See more WebHISTORY.
