(3) high-speed diesel engine idling adjustment

When a diesel engine operating temperature, the transmission in the free position, clutch separation, open the throttle and maintain full position to observe the highest speed diesel engines. This should speed than the speed governor off point of 10% ~ 12% (depending on fans, pumps and other accessories load). If the value exceeds should troubleshooting.

(4) the fuel outlet pressure checks and adjustments

Inspection PT fuel injection pump outlet pressure of the following three methods:
      check point disconnect speed governor, and then to full throttle, increasing load up to speed diesel engine rated (should be used speed and high precision table), read out the fuel outlet pressure. If the pressure below the minimum requirement or in excess of the maximum value, should be adjusted as follows: to increase the pressure on, we should pinch out the biggest opening of the throttle adjustment screws, remove the throttle shaft adjusted as necessary to join pad tablets; to reduce pressure can be reduced pads. But in any case, should not the PT fuel pump
Transferred to the export of fuel pressure above the maximum specified value.
      full throttle, from low to high speed, pay attention to fuel exports greatest pressure. Manometer with appropriate buffer, this method is more reliable.
      instantaneous pressure checks, first Unscrew the valve off oil pressure gauges installed on the Luosai, and then installed manometer; undocked from the throttle rod connector throttle control will be transferred to the throttle-clockwise Nail the block.
Starting diesel engines, the throttle slightly open, diesel engine speed increased to higher than idling 200 ~ 300 r / mln. Then, suddenly pull to full throttle position, to allow diesel engines to accelerate to maximum speed, and observe the pressure gauge, to the maximum instantaneous pressure, and has repeatedly tested many times. This method is simple, but is less accurate.
Check with smokeless diesel engine limiter booster, the fuel flows through the pipeline limiter was smoke should be blocked or removed.
