Abstract: PURPOSE: 50 percent of maximum value of needle lift signal is set as a reference point, and upper and lower 25 percent are linearized. A formula is applied with these values, to determine injection starting and ending time. CONSTITUTION: In a diesel engine, a crank angle data(X) and needle lift signal(Y1) are sensed. 50 percent of maximum value of the needle lift signal(Y1) is set as a reference point, and plus and minus 25 percent of the reference point is determined as a linearization data process range. Data is linearized by a formula, Y=C1X + C0. Injection starting and ending point are calculated by a formula, X=-C0/C1.
