Abstract
A portion of the engine cooling water flowing from the cooling water pump through the engine and the radiator back to the cooling water pump is introduced into the carburetor through piping to heat the carburetor. The downstream side of the carburetor piping is connected to by-pass piping connecting a thermostat valve provided in the radiator piping at a position downstream of the engine and the intake port of the cooling water pump. Accordingly, engine cooling water flows mainly into the by-pass piping when the thermostat valve is closed, and flows mainly into the radiator piping when the thermostat valve is opened. The carburetor is therefore heated even before the thermostat valve is opened immediately after actuation of an engine. In addition, excessive heating of the carburetor after the engine is appropriately heated is prevented without using a special switching valve.
