4.2.4.2. Adjustment of initial pressure of injection

GENERAL INFORMATION

Torch of dispersion of fuel

Initial pressure of injection is regulated by laying installation under a spring. The increase in thickness of laying increases pressure of the beginning of injection, reduction – reduces. Change of thickness of laying approximately changes pressure of the beginning of injection upon 1 kg/cm2 to 0,01 mm.

Indispensable condition of work of a nozzle is quality of dispersion. The torch of dispersion should be uniform on all cross-section section of a cone of dispersion, and dispersion should be misty.

The beginning and the end of injection should be accurate. At new nozzles injection is accompanied by a sharp sound, At working nozzles lack of this sound is not a malfunction sign.
