Abstract

PURPOSE: To prevent an engine effectively from overheat by a method wherein two cooling water supply paths are provided and when one of them is choked cooling water is supplied from the other.
CONSTITUTION: The main path 7 adjoins an exhaust path 1 in a lower casing (b) and an intake 10 is provided on the lower part of the main path. A subsidary path 8 is provided in the internal part of a padding on the internal wall of the lower casing (b) and extended toward the rear of the lower casing (b). The intake 16 takes cooling water into a space part 13 and a wall 17 hanging from the rear edge of the intake 16 is provided for an effective intake. The cooling water taken in from each path 7, 8 is supplied to the engine by a water pump 6 through a feed pipe 9. Hence, when one of the intakes 10, 16 is choked, the cooling water is taken in from the other intake and can be supplied to the engine.
