摘要： PROBLEM TO BE SOLVED: To provide an EGR device for an internal combustion engine with a supercharger showing fuel economy improving effect over a whole operation zone.
SOLUTION: This EGR device comprises an EGR pipe 10 taking part of exhaust gas out of an exhaust gas passage E1 in an exhaust gas upstream of a turbine T1 of a supercharger T and re-circulating the same to an intake air passage E2 in an intake air downstream of a compressor T2 of the supercharger T, and an ejector 20 provided in the EGR pipe to position a nozzle in an EGR gas upstream side and a diffuser in an EGR gas downstream side and making a suction chamber communicate to an intake air passage E2. Since intake air flow rate can be increased together with EGR gas flow rate by sucking intake air by EGR gas and mixing the same with using the ejector 20, opening of a EGR control valve can be made wide even in light load zone, exhaust gas pressure is reduced to reduce differential pressure with intake air pressure, and improvement of fuel economy by improving intake and exhaust resistance can be expected.

摘要： PROBLEM TO BE SOLVED: To improve a NOx conversion rate and the availability of a urea aqueous solution as a reducing agent precursor by actively controlling the amount of the urea aqueous solution or ammonia occluded in a NOx reduction catalyst, in an exhaust emission control device for reducing and converting NOx in exhaust emission. SOLUTION: After an engine is started, when an exhaust emission temperature introduced into the NOx reduction catalyst becomes higher than a predetermined temperature T (S1), the injection and supply of the urea aqueous solution is started (S2) regardless of an engine operating condition. Then, the concentration of ammonia and the concentration of Nox downstream of the exhaust emission of the Nox reduction catalyst are always monitored. When the concentration of ammonia reaches an allowable upper limit C NH3 (S3), the injection and supply of the urea aqueous solution is stopped (S4). Meanwhile, when the concentration of ammonia becomes smaller than the allowable upper limit C NH3 and the concentration of NOx reaches a target value C NOx or larger (S5 and S6), a process is finished (that is, the process is repeated from S1).
