<P>PROBLEM TO BE SOLVED: To provide an engine enabling a plurality of variable supercharging systems to be accurately controlled. <P>SOLUTION: This engine includes a supercharging system 9 having a first supercharger 10 and a second supercharger 20 which has a capacity different from that of the first supercharger 10 and is arranged parallel to the first supercharger 10, a first turbo-sensor 61 for detecting a first turbo rotational speed Nta_1, a second turbo-sensor 62 for detecting a second turbo rotational speed Nta_2, a first variable vane 13 for adjusting the capacity of the first supercharger 10, a second variable vane 23 for adjusting the capacity of the second supercharger, and an ECU 60 for adjusting the opening of the first variable vane 13 and the opening of the second variable vane 23. The ECU 60 adjusts the opening of the first variable vane 13 according to the supercharging pressure and the first turbo rotational speed Nta_1, and the opening of the second variable vane 23 according to the supercharging pressure and the second turbo rotational speed Nta_2. <P>COPYRIGHT: (C)2010,JPO&INPIT |
