Abstract: A method for extending the operating range of engine fuel injectors fed by a pressurized fuel system includes operating the fuel system at a controlled lower fuel pressure during engine operation in a lower power range, and operating the fuel system at a controlled higher fuel pressure during engine operation above the lower power range. An engine embodying the method may include a fuel distributor connected with the injectors for supplying the pressurized fuel and a pressure control operative in response to a prescribed engine condition, such as supercharger boost pressure, to maintain injector fuel supply pressure at a lower value during engine operation in a lower portion of the power range and at a higher value during engine operation in a higher portion of the power range. The dual or multiple fuel pressures provide greater fuel output for increased power in the higher power range with consistent fuel delivery for stable idle and engine operation in the lower power range.

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.

Abstract: The refrigerant compressor of a motor vehicle air conditioning system in which the compressor is normally cycled on and off according to cooling demand is maintained continuously on or continuously off during idle operation according to a measure of the compressor duty cycle. During non-idle operation, a measure of the compressor duty cycle is compared to a reference duty cycle corresponding to a cooling demand above which it is desired to maintain the compressor on during idle operation and below which it is desired to maintain the compressor off during idle operation. At the onset of idle operation, the compressor is maintained on or off, and at the expiration of a time period corresponding to the duration of idle operation typically encountered in stop and go driving, normal compressor cycling is resumed.
