摘要： A control apparatus for an internal combustion engine according to the invention is applied to an internal combustion engine in which EGR gas and condensed water generated by an EGR cooler are supplied into a cylinder. The control apparatus calculates an equivalence ratio of the internal combustion engine, and controls an EGR valve and a condensed water supply valve such that, when the equivalence ratio is high, a supply rate of the condensed water increases and a supply rate of the EGR gas decreases relative to when the equivalence ratio is low.

摘要： An engine includes an exhaust gas recirculation system with a high pressure exhaust gas recirculation loop and a low pressure exhaust gas recirculation loop, and an air charging system. A method of controlling the air charging system includes monitoring an actual exhaust gas recirculation rate, operating conditions of a compressor and turbine in the air charging system. A compressor flow is determined based on a target exhaust gas recirculation rate, a target intake manifold pressure and the actual exhaust gas recirculation rate. A power requested by the compressor is determined based on the compressor flow, the target intake manifold pressure, and the monitored operating conditions of the compressor. A power to be generated by the turbine is determined based upon the power requested by the compressor. A turbine flow is determined based upon the power to be generated by the turbine and the monitored operating conditions of the turbine. A system control command is determined based on the turbine flow and the monitored operating conditions of the turbine. The air charging system is controlled based on the system control command.

摘要： An EGR cooler and an EGR cooler device includes a pre-cooler which is located at a central region at which a cooling water chamber of an EGR cooler housing, in which cooling water circulates, is divided into two spaces, and in which hot exhaust gas introduced from an exhaust system is discharged as primary-cooled exhaust gas via heat-exchange with the cooling water. Therefore, it may be possible to reduce costs by a decrease in number of EGR tubes via optimal primary cooling performance for the exhaust gas in the pre-cooler and particularly to relieve damage by a thermal load generated due to the hot exhaust gas by fully surrounding an inlet and an outlet of the pre-cooler with the circulating cooling water.
