PURPOSE:To reduce the load of an automobile internal combustion engine equipped with a fuel injection pump and the air conditioner, by stopping a compressor for the air conditioner when the fuel temperature has exceeded a set temperature. CONSTITUTION:When the detected value of a fuel temperature detector 5 or a temperature detector 9 has exceeded, a thermoswitch 4 is turned off. Therefore, an electric current from a battery 1 through an air conditioner controlling circuit 2 to a magnetic clutch 3 is cut off and the compressor for the air conditioner is stopped. Thus, when the fuel temperature becomes above a prescribed temperature, the compressor is forcibly stopped, so that load on the engine is lessened, and lowering of the output consumed for driving the vehicle during great output lowering resulted from the fuel temperature elevation can be suppressed. |
