PURPOSE:To permit to effect the start warming under heating the air suction system of the engine upon the starting operation thereof by providing a part of a cooling liquid path so as to be contacted with a bent part formed in the air suction path of air suction system of the engine communicating the air suction port of the main body of the engine with a carburetor. CONSTITUTION:A part of a cooling system is contacted with the bent parts 12b, 12b' of branch tubes 12a, 12a' brached at the tip end of an inlet manifold 12. A bracket 13 is arranged and welded so that the bracket 13 rides over the outer peripheral part of both branched bent parts 12b, 12b' and the through hole 13a thereof is orthogonal to the extending direction of the branch tubes 12a, 12a'. The connecting tube 14, connecting the flow paths of the cooling system is attached to and penetrated through the through hole 13a of the bracket 13 while the liquid path and the connecting tube 14 are connected through a rubber hose 15 or the like. According to this method, heating of mixture may be promoted further. |
