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
