Abstract: A fuel injector assembly includes a plularility of fuel injectors, each of which may have a different performance characteristic. After the performance characteristics have been determined, an internal, energizable voltage or current source is provided within the injector housing. Each time the vehicle ignition is turned on, a controller queries each injector to obtain a signal from the individual, internal, energizable voltage or current sources. The controller then uses the output of the internal voltage or current source as an indication of the performance characteristics of each injector. The controller then customizes the power signal supplied to each injector to accommodate for different performance characteristics.

Abstract: A vehicle power supply management system includes a load absorbing device that absorbs an excess voltage from the vehicle battery. Under circumstances, such as at vehicle shutdown when an excess voltage spike occurs at the battery, the load absorbing device is selectively coupled to the battery to absorb the excess voltage and protect other electronic components on the vehicle. In one example, a comparator compares the voltage on the battery to a preselected threshold value. Whenever the battery voltage exceeds the threshold, the inventive arrangement selectively couples a load absorbing device, such as a plurality of glow plugs, heating elements within a vehicle seat or a window defrost unit, for example, to the vehicle battery to absorb the excess voltage.
