Background technology
Exhaust gas recirculatioon is that a part for Exhaust Gas goes out and import suction side to make by automobile compact internal combustion engine after combustionIts air-breathing once again technology (gimmick or method), main purpose is reduce the nitrogen oxide in Exhaust Gas and share partDuring load, rate of fuel consumption rate can be improved, get the prefix " EGR " of its each English individual character for common name. Exhaust gas recirculatioon EGRThe effect of system is the discharge that reduces oxynitrides. Nitrogen oxide is under the high temperature conditions, is sent out by airborne oxygen and nitrogenRaw reaction is and the compound of formation, and visible nitrogen oxide is not to derive from fuel, but from air. Therefore, burning temperatureSpend higher, high-temperature duration is longer, and the growing amount of nitrogen oxide is more; Ignition advance angle is larger, and burning temperature can be affectedThe raising of degree, thus the concentration of emission that adds nitrogen oxide. According to the different operating modes of engine, by a part of waste gas againBe incorporated in cylinder, with combustion mixture mixed combustion again, thus reduce burning velocity and temperature, decrease nitrogen oxidationThe growing amount of thing. The introducing of EGR can reduce the flammability of fuel gas, makes the power of engine decline to some extent, thereforeThe most general control of circulation of EGR is about 5%-15%. Therefore, when high load capacity operating mode, engine needs largerExhaust gas recirculation rate, to reduce row's temperature, reduces to pollute; When small load condition, engine needs less rowGas recirculation rate, to improve the dynamic property of engine.
