The present invention minimizes the detrimental effect of any misreading error by assigning adjacent code values in such a way that between adjacent values, only one characteristic changes, and that characteristic only changes by a one value. If the codes are assigned in rows and columns, then it will be true that adjacent code numbers can be associated with physical states of the system wherein both characteristics are different, and the characteristics may be different by several factors.Īny misreading error is likely to be between adjacent code values. The present invention minimizes the ill effect of any such reading error by assigning the coded information in a fashion other than beginning at the same point within a row or column and returning to this beginning point. Moreover, the voltage sources which drive the system may also vary from a predicted value, and can also result in error. Thus, the resistors themselves can result in voltage errors. As with any manufactured item, there are tolerances within the resistors.

As examples, the disclosed embodiment utilizes resistors to provide the code voltage. A number of different factors can influence and cause such errors. It would be desirable to minimize the detrimental effect of when a particular monitored voltage is associated with particular set of characteristics by the control, but wherein the injector actually possesses a different set of characteristics than that which the control has identified. One challenge with this type of system would be identification errors, in which the control misidentified the particular signal as being a code other than the proper code. This basic system is disclosed in co-pending patent application Ser. The control reads an electronic signal influenced by the voltage, and can thus identify the particular code, and thus the combination of characteristics.

The fuel injectors can vary with manufacturing tolerances, and by sensing the identifying voltage the control can identify how the particular fuel injector would be best controlled.Ī series of distinct voltages are associated with different combinations of two characteristics. The identifier provides feedback to a control for driving the fuel injectors on characteristics of the fuel injectors. The present invention is specifically directed to a method of providing a coded identifier through a voltage associated with particular types of fuel injectors. The codes preferably provide information with regard to at least two characteristics of the physical system, and are assigned in such a way that any misreading is likely to have minimal effect. This invention relates to a method of assigning coded quantities to provide an identification of particular aspects of a physical system.
