Oil supply time inspection method
First, the pulsation method will remove the upper end of the high pressure tubing, so that the top end down, when the pump oil to the top of the oil, slowly flywheel, found that the oil pulsate slightly, that is, start the oil supply time, look at this time on the flywheel The oil supply is engraved on the water tank to mark the line. Second, cut off the oil to remove the fuel pump on the tight seat, remove the outlet valve, let the diesel out. The flywheel is rotated (in the direction of rotation during operation). When the plunger plugs into the oil return hole, the diesel will stop outflow, which is the start of the oil supply time. Third, the empirical method is based on the different symbols of engine operating conditions and faults, to determine whether the oil supply time is accurate. When the engine is working, there is a knocking sound, indicating that the oil supply time is too early. The time for oil supply can be postponed until it is eliminated.
