PURPOSE:To prevent the voltage of a battery charged with the positive output from being badly influenced by heating a temperature sensitive valve provided in the path of cold engine starting auxiliary fuel supply unit of a carburetor by means of negative output of an a.c. power source. CONSTITUTION:The output from the charge coil 1 of an a.c. generator 2 provided with flywheel magnet or others charges a battery 5 through a rectified voltage regulator 3 and then is transmitted to loads through a main switch 6. The ouput from the intermediate tap 7 of the charge coil 1 is transmitted to various loads through a switch 8. On the other hand, a carburetor 10 is equipped with a fuel path 11 for cold start in addition to the normal fuel system. The fuel path 11 is opened and closed by a piston 19 and a rod 13 acutuated due to the thermal expantion of a wax 16 while a heating element 15 is heated. The heating element 15 shall be heated only by negative output from a rectifier 26 so that the battery and other loads operated with positive output may not be. |
