(1) the fuel supply time debugging.Removed all the tubing connector, turn the dial to make 1 cylinder oil outlet began to take oil, aim the ruler scale an integer as a 0 scale, turn the dial, according to the work order to observe whether the interval of each cylinder oil supply Angle of 60 degrees (six cylinder fuel pump), the deviation in the range of 0.5 degrees.
(2) the fuel starting debugging.Starting test rig, to set the speed at 200 RPM, fuel injection times set in 200, the rotation manipulation arm to maximum oil supply position, push button counts.Standard fuel injection quantity should be 26 ml, abnormal injection quantity can be adjusted respectively each cylinder fork in the oil supply on the rod position.
(3) to debug the rated speed the flow of oil.Starting test rig, in addition to the set speed at 900 RPM, (2) with other steps.Standard fuel injection quantity should be 26 ml, such as fuel injection quantity is not normal, can be adjusted by adjusting the rated speed fuel quantity adjusting screw for unity.
(4) to debug the idle speed the flow of oil.Starting test rig, to set the speed at 250 RPM, fuel injection times set in 200 times, push button counts.Standard fuel injection quantity should be 6 ml, such as fuel injection quantity is not normal, can be adjusted by adjusting the idle oil screw to adjust.
