(4) After multiple injection, the front end of the injector should not be dripping oil.
⑤ The injection cone Angle should comply with the regulations. The test method is to put a piece of white paper vertically down the injector, 200 mm away from the injector, and then make the injector spray under normal working pressure, measure the diameter of the oil mark on the white paper, its diameter should be between 14 ~ 42 mm.
Two, check and adjust on the engine
The fuel injector to be checked is connected to the standard fuel injector in parallel with a special tee pipe, and is connected to the high pressure tubing of the fuel injection pump. At the same time, the high pressure tubing of other cylinders is loosened to prevent oil injection into each cylinder. And then put
The throttle is placed in the maximum position, and the motor or hand crank shaft is started under the condition of decompression. After the air is removed, observe their oil injection. If the injector is injected first, the injection pressure is too low; If the tested injector after the injection of oil, indicating that the injection pressure is too high, it should be adjusted to the standard injector at the same time.
Three, the injection pressure of the injector is adjusted by experience method
Adjusting the injection pressure of the injector should generally be carried out on the injection pressure test bench. Under the condition of no test bed, if it is confirmed that the technical status of the fuel injection pump is basically normal, the pressure of the fuel injector at the beginning of the injection can be adjusted directly on the vehicle by using the empirical method.
