It is that strict requirement is arranged that Injection Pump began to the moment of oil sprayer fuel feeding, and it has influence on motor starting characteristic, power character, Economy, smoke intensity, noise and discharging multinomial performance.In engine test, to adjust fuel supply advance angle, after the client uses motor for a long time, also need to adjust fuel supply advance angle, whether easy to adjust, be related to the use and maintenance of motor.
The dismounting of Injection Pump:
1, with engine revolution to first cylinder be in compression top center fuel feeding position or near.
2, unclamp six Injection Pump cover plate clamping bolts 8, take off Injection Pump cover plate 5.
3, unclamp and take off four (M8) Injection Pump driving gear clamping bolts 9.
4, unclamp and take off each cylinder high-pressure oil pipe.
5, unclamp and take off the nut of three (M8) fastening Injection Pumps.
6, take off injection pump of engine 4.
Pressing reverse sequence during assembling installs.
The Injection Pump fuel supply advance angle is adjusted:
1, unclamps and take off six (M8) Injection Pump cover plate clamping bolts, take off the Injection Pump cover plate.
2, unclamp four (M8) Injection Pump driving gear clamping bolts, as long as pine can move mutually to driving gear and adpting flange.
3, with the socket wrench rotation Injection Pump shaft end nut of M19, the fuel feeding that turns clockwise is rotated counterclockwise fuel supply advance angle and reduces ahead of time.
4, after the adjustment that the Injection Pump driving gear is fastening, Injection Pump cover plate and fastening is installed.
