    Abstract: An exhaust gas recirculation system includes: a turbocharger (8) that includes a compressor (8a) and a turbine (8b); a throttle valve (7), provided in an intake passage (3) upstream of the compressor (8a); an EGR passage (11) through which a portion of exhaust gas from the exhaust passage (4) is recirculated to the intake passage (3) between the throttle valve (7) and the compressor (8a); and an EGR valve (13) that regulates a flow rate of exhaust flowing in the EGR passage (11). The exhaust gas recirculation system further includes valve control means that controls the opening degree of the throttle valve (7) and the opening degree of the EGR valve (13) so that the pressure in the intake passage (3) between the throttle valve (7) and the compressor (8a) is maintained at or above a predetermined pressure.

    Abstract: The invention calculates a second order differential of at least one of an airflow rate of a centrifugal compressor (26a) (step S 108) and a pressure and a temperature of air in an inlet of the centrifugal compressor. Then, the invention determines whether the calculated second order differential is equal to or greater than a predetermined value (step S 110). If the number of times (counter value) the second order differential is determined to be equal to or greater than the predetermined value reaches or exceeds a threshold value (step S 116), the invention determines that a surge occurs in the centrifugal compressor (26a) (step S 118).

    Abstract: The invention relates to an exhaust gas purification system applied to an internal combustion engine. The engine has a turbocharger (40) including a turbine wheel (45) and a housing (42H) for housing the turbine wheel. The housing defines a turbine outlet passage (44) communicating with an exhaust gas discharging part (49) of the turbine wheel. The engine further has an exhaust passage part (34) communicating with an exhaust gas outlet (44O) of the turbine outlet passage. The system comprises an exhaust gas purification apparatus disposed in the exhaust passage part at a position adjacent to the exhaust gas outlet of the turbine outlet passage. Further, the apparatus includes an exhaust gas purification member (51). The member is provided such that its density in a peripheral part (34P) of the exhaust passage part is larger than that in a central part (34C) of the exhaust passage part and a flow passage resistance per unit volume of the member at an area of the central part of the exhaust passage part is smaller than that at an area of the peripheral part of the exhaust passage part.
