PURPOSE:To protect equipments, etc., arranged on a driver's seat side from the heat injury by a supercharger by providing primary and secondary side exhaust turbosuperchargers, and arranging the primary side supercharger actuat ed at least at the time of low speed closer to an assistant's seat side to the center in the body right and left direction. CONSTITUTION:The intake passage 3 of an engine 1 is branched to branch intake passages 3a and 3b at the downstream side of an air flow meter, their downstream sides are joined at the upstream side of an intercooler 5, and also blowers Cp and Cs of primary and secondary side turbosuperchargers 9 and 10 are correspondingly arranged to passage 3a and 3b. Though each super charger 9 and 10 is arranged to the direct rear part of each right and left side bank 61R and 61L, in this case, the supercharger 9 actuated at least at the time of low speed is positioned closer to an assistant's seat side to the center in the body right and left direction. This enables the heat injury, by the said supercharger 9 to the equipments, etc., of a master cylinder or assistor etc., arranged to a driver's seat side, to be prevented. |
