    摘要: A fuel injector assembly includes a plurality of fuel injectors (22), each of which may have a different performance characteristic. After the performance characteristics have been determined, an internal, energizable voltage or current source (28) is provided within the injector housing (23). Each time the vehicle ignition is turned on, a controller (26) queries each injector (22) to obtain a signal from the individual, internal, energizable voltage or current sources (28). The controller (26) then uses the output of the internal voltage or current source (28) as an indication of the performance characteristics of each injector (22). The controller then customizes the power signal supplied to each injector to accommodate for different performance characteristics.

    摘要: A method for identifying particular characteristics of a physical system includes assigning codes information to the system based upon two distinct characteristics. The code increases in value, with increasing code numbers being assigned to combination of the characteristics in such a way that between any two adjacent code values, only one of the two characteristics change, and the increasing value only changes by one value level.

    摘要: A method for identifying particular characteristics of a fuel injection system places a characterization resistor into a power circuit for each fuel injector. The resistance is selected once the characteristics of the fuel injector have been tested after assembly. The control for the fuel injector is able to query the particular fuel injector and determine its characteristics based upon a voltage which has been influenced by the characterization resistance. In another feature of this invention, coded information, such as the characterization resistance, is assigned to a number of possible combinations of characteristics in a spiral fashion if the characteristics were stored in a two dimensional array.

    摘要: A fuel injector coil control circuit includes high side and low side gates. The current through the coil is increased while being monitored by low side shunt circuitry. The current continues to increase until a predetermined value is reached. When the predetermined value is reached, the low side gate is switched off and the current begins to decay. The off time of the low side gate is controlled for a predetermined period of time. After the predetermined period of time elapses, the low side gate is switched back on, causing the current to rise again toward the predetermined value.

    摘要: A method and system is disclosed by which identification codes for a plurality of systems are utilized to provide a control with an indication of a particular characteristic of the particular system. The characteristic is assigned with an identifying variable, in a disclosed embodiment voltage, which increases. As this variable increases, possible errors due to system features will also increase. Thus, the possibility of the control misreading an identification code due to the error increases. To address this increasing possibility, the distance between adjacent variables also increases as the variables themselves increase. In a preferred embodiment the distance is increased proportionally.
