PURPOSE:To prevent width of a car body from widening, and shorten the length of a cooling pipe passage, by arranging a cooling pipe passage on a space generated on the way of the return part of each exhaust pipe extending from each cylinder of an engine. CONSTITUTION:Each left/light exhaust pipe 29 extending from each of cylinders 24 is firstly projected front-downward from the cylinders 24, and returned backward, then extended backward. Each exhaust port of the left/light cylinder 24 is apart from a prescribed distance so as to generate excess space 65 on the way of the return part 64 of each exhaust pipe 29 front end. In the space 65, a thermostat 44 served as a cooling pipe passage, a second pipe 47, and a bypass pipe 52 of a pipe 2 are respectively arranged. It is thus possible to shorten the cooling pipe passage connecting an engine with a radiator. |
