Test data 104749-1790
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 N = N1, adjust using shims so that the decrease amount for altitude is as specified in the graph. N:Pump speed X1:Atmospheric pressure X2:Altitude Y:Decrease quantity A:Adjustment value B:Inspection value

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod so that the clearance between the control lever and the FICD shaft is S1. 2. Apply negative pressure P1 to the actuator and confirm the full stroke.
----------
S1=1+1mm P1=-53.3kPa(-400mmHg)
