Chronological positioning method for signals of lambda probe involves trimming of cylinder to respective values during a period of time, specifying differential input, determining its time and specifying time interval from time difference

摘要

Method involves trimming of cylinder to value(.lambda 1) during a time period (.t1) and determining signal of lambda probe (lP1), trimming of cylinder to second value (.lambda 2) during second time period (.t2) and determining signal of lambda probe (lP2). The differential input (lPB=lP1-lP2) is specified, its time determined and time interval (tZ) is specified from time difference (time tM-reference time tO).
