Diesel Fuel Injector 1933613 for Scania Xpi Engine DC1

The fuel supply time is too early. When the fuel is fed too early, the mixture will burn too early, creating too much pressure to push the piston back up, causing the crankshaft to reverse overload. Due to the overload of diesel engine, slow down to about flamed out, the flywheel running speed is close to or equal to 0, and the piston upward movement is in the range of oil supply Angle, at this time if the separation of the clutch, it will be due to the diesel engine overheating, so that the fuel injection into the cylinder rapid combustion, promote not over the top dead center of the piston down and reverse. Glide uphill. The tractor is on the way to turn off the engine. If the clutch is not separated and the gear is not picked, the landslide will occur. At this time, the diesel engine will be driven by the driving wheel through the transmission mechanism. Flywheel roll key. The flywheel was badly rolled, the keyway was broken, and the resulting timing misalignment caused the diesel engine to reverse.

In the process of use, it is found that the engine injector or nozzle is easy to damage. After the technical identification of the manufacturer, it is believed that the diesel oil quality is not up to the requirements of the fuel injector damage. In order to improve the service life of the fuel injector, we have taken the following measures to improve the diesel oil quality:

(1) Add a filter at the refueling port of the diesel tank, so that it can play the role of crude filtration when adding diesel; A filter element is added between the original one and two filter elements, so that the diesel fuel entering the fuel injector can be changed from the original two filter to four filter.

(2) Timely clean impurities in the filter cup, regularly replace the diesel filter element, and often clean the diesel oil tank to remove precipitated impurities in the tank.
