    摘要: An engine is activated to drive a generator when an electrical output is required. The required electrical output (PO) is searched and the necessary engine output is calculated. The basic driving point (NO, TO) which obtains maximum fuel efficiency is set at that output (S101-S105). The load of the generator is controlled so as to reach the set basic driving point. When the catalyst temperature is lower than a set value, while maintaining the required electrical output, the basic driving point is varied to a driving point (Ncold, Tcold) which will raise the exhaust gas temperature (S106-108). Furthermore when the temperature of the peripheral engine components in the engine room is higher than a set value, while maintaining the required electrical output, the driving point is varied to a driving point (Nheat, Theat) which will lower the exhaust gas temperature (S109-S111). Hence while maintaining the electrical output, it is possible satisfy each component temperature condition. Therefore while maintaining drivability, fuel efficiency performance, lowering exhaust gas emissions and component deterioration can suppressed.
