0000001501 ANEROID COMPENSATOR

ACS adjustment Full load injection quantity at high altitudes and ACS adjusting method 1. Full load injection quantity adjustment (1)Remove the ACS cover and remove the bellows and adjusting shim. (2)Perform all adjustments as per the adjustment standard except for ACS adjustment. 2. ACS adjustment (1)Assemble the ACS cover, bellows and adjusting shim. (2)At pump speed N1, adjust using a shim to obtain the decrease for the altitude shown in the table. X1 = atmospheric pressure X2 = altitude Y = decrease quantity (A) = adjustment value (B) = test value

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD (vacuum-type fast idle control device) 1. Adjust the actuator rod so that the clearance between the control lever(A) and the actuator rod is L. 2. Apply negative pressure P1 {P2} to the actuator and confirm that it moves through its full stroke. (A) Control lever (B): lock nut (C): Actuator (D): Stroke adjusting screw

0000001901 POTENTIOMETER ADJUSTMENT

Adjustment of the potentiometer At pump speed N = N1 r/min and with the control lever angle at a from the idle position (corresponding to a shim thickness of L mm), convert the injection quantity obtained to a voltage value using the graph below and adjust the potentiometer. Vi:Applied voltage Caution: Confirm that the voltage increases when the control lever is turned to the full speed side. D = target injection quantity Q1 at pump speed N1. C = control lever position Vo = output voltage Qi = injection quantity A = adjusting point B = target value N = pump speed Q = injection quantity P = boost pressure E = conversion expression
