PROBLEM TO BE SOLVED: To suppress an anxiety that the suction force of a magnet clutch 18 drops due to a temperature rise, and the efficiency drop of an air conditioning compressor 24 and the wear of a clutch surface due to the elongation of a time period required for a clutch connection.SOLUTION: The turning force of a crankshaft 14 is transmitted through a magnet clutch 18 disposed in the vicinity of an engine 12 to an air-conditioning compressor 24. An ECU 26 applies a pulse voltage to a coil 18c when the magnet clutch 18 is connected to the crankshaft 14. However, the duty ratio of a pulse voltage to be applied is so adjusted by the ECU 26 that the ratio of an ON time may increase in response to the rise of the temperature of the engine 12.SELECTED DRAWING: Figure 1

    【課題】温度上昇に起因してマグネットクラッチ18の吸引力が低下する懸念、ひいてはクラッチ接続に要する時間が長期化することによる、空調用コンプレッサ24の効率低下およびクラッチ面の磨耗を抑制すること。【解決手段】クランクシャフト14の回転力はエンジン12の近傍に設けられたマグネットクラッチ18を介して空調用コンプレッサ24に伝達される。ECU26は、マグネットクラッチ18をクランクシャフト18に接続する際に、コイル18cにパルス電圧を印加する。ただし、印加されるパルス電圧のデューティ比は、エンジン12の温度の上昇に応じてオン時間の割合が増大するように、ECU26によって調整される。【選択図】図1
