<P>PROBLEM TO BE SOLVED: To improve the starting characteristic of an internal-combustion engine which uses alcohol-mixed fuel. <P>SOLUTION: An engine ECU 100 of this hybrid system 10 executes a start control process, in which the number of cranking revolutions and a fuel injection amount are decided in compliance with the alcohol concentration of the fuel and the cooling water temperature of the engine 200. At this time, the number of cranking revolutions is set such that the higher alcohol concentration is, and the lower temperature of cooling water is, it is made the smaller. On the other hand, the fuel injection amount is set such that the higher alcohol concentration is, and the lower temperature of cooling water is, it is increased the more. When the number of cranking revolutions and the fuel injection amount are set, the engine ECU 100 controls a motor 500 as one of the power sources of the hybrid car 20 so as to accomplish the decided number of cranking revolutions and controls an injector 207 so that the decided injection amount is achieved. <P>COPYRIGHT: (C)2007,JPO&INPIT |
