摘要： PROBLEM TO BE SOLVED: To improve exhaust emission control and operation performance by stabilizing fuel vaporization, by performing operation control of an optimal engine in response to the alcohol concentration. SOLUTION: The engine is controlled for operation in response to an operation action line corresponding to the detecting ethanol concentration. When an output increase is requested, engine torque is improved by increasing opening of a throttle valve, and an engine speed is increased by driving of a motor generator and shift operation by a power dividing mechanism. At this time, the operation action line turns in the direction for increasing the engine speed as the ethanol concentration becomes high (in the direction for restraining an improvement in the engine torque). That is, on this output line, an operation action point of the high ethanol concentration is set in a higher position in the engine speed than the operation action line of the lower concentration than its ethanol concentration.

摘要翻译：要解决的问题：通过响应于酒精浓度对最佳发动机进行操作控制，通过稳定燃料蒸发来提高废气排放控制和操作性能。解决方案：响应于与检测乙醇浓度相对应的操作动作线，控制发动机进行操作。当要求输出增加时，通过增加节流阀的开度来提高发动机扭矩，并且通过驱动电动发电机并通过动力分配机构进行换档操作来提高发动机转速。此时，由于乙醇浓度变高（在抑制发动机转矩提高的方向）上，操作动作线向着提高发动机转速的方向转动。也就是说，在该输出线上，高乙醇浓度的操作动作点被设定在比其乙醇浓度低的浓度的操作动作线的发动机转速的较高位置。版权所有（C）2009，JPO＆INPIT
