Fuel spray torch
The initial injection pressure is adjusted by installing a gasket under the spring. Increasing the gasket thickness increases the injection start pressure, decreasing it decreases it. Changing the gasket thickness by 0.01 mm changes the injection start pressure by approximately 1 kg/cm².
A mandatory condition for the operation of the injector is the quality of spraying. The spray torch must be uniform across the entire cross-section of the spray cone, and the spray must be foggy. The beginning and end of the injection must be clear. In new injectors, the injection is accompanied by a sharp sound; in injectors that have been in operation, the absence of this sound is not a sign of a malfunction.
