Alcohol concentration level of flex fuel is estimated based upon in-cylinder ionization signals. The in-cylinder ionization signals are integrated and the rotational completion point of a chosen percentage of the integration total is identified as the integration location for the operating conditions under observation. The calculated integration location correlates with alcohol concentration level of flex fuel, and the integration calculations provide a basis for a virtual flex fuel sensor that provides calculated estimates of alcohol concentration rather than direct sensing using an expensive physical flex fuel sensor.

An apparatus for providing electrical power for a hybrid vehicle includes an integrated starter-generator and an inverter connected to an electrical energy storage device such as a capacitor and a battery by first and second switches respectively. A control turns the switches on and off in accordance with selected modes of operation to provide power from the capacitor to the integrated starter-generator and the battery and to provide power from the integrated starter-generator to the capacitor and the battery.
