ABSTRACT:
The present invention provides a flexible fuel internal combustion engine utilizing impulse charging technology. The internal combustion engine includes a fuel sensor which determines the type of fuel currently being supplied to the engine, for example, either gasoline or E85. Based upon this determination, the impulse charging will be inactive (if gasoline is sensed) or active (if E85 is sensed). A speed or torque sensor is also utilized to determine if impulse charging will produce a volumetric efficiency that is better matched to the fuel octane characteristics.
