2. Further adjustment of the injection pump technique
(L) fuel pump installed, according to the required standards for good oil supply, exhaust manifold unloaded at the same time, to observe the work of the cylinder.
(2) start diesel engine, idling idling 2 ~ 3 min, hand-to-mouth and the cylinder exhaust injector near the cylinder head, if a cylinder temperature is too high, may be initially determined that the cylinder of excessive supply.
(3) When the temperature of more than 50 ��, increasing throttle, the engine operates at the rated speed, the exhaust ports at the same time see the smoke color, to listen to the voice of the cylinder. If a cylinder smoky, the excessive supply, construction machinery installed to spend more of the 135 series engine as an example, the fuel pump can be regulated to stop oil tooth-pulling direction, loosened regulation on the locking screw gear , a small crowbar take control of the oil sleeve inserted in the holes with hammer tapping to the right moment, can reduce the supply of, otherwise increase.
When a cylinder with sharp percussion sound, and start difficulties, the supply began prematurely; if a cylinder temperature high, and even flame out, it may be late starting time is supply. Such as the 135 series engine, the cylinder oil starting time adjustment, is the location of the plunger pumps decision. When the late starting time of supply, should regularly adjusting nut and screw some rotation, the starting time of early oil, some of this screw tightening.
