A Study on Dynamic Parameters of Fuel Injection Pump

The authors measured and studied rack displacement pattern and injection advance angle of fuel pump on 6130Q diesel engine at both steady and speed change conditions.

By means of injection pattern and indicator diagrams actually measured at the same time, this paper deals with the important roles of fluctuation of rack displacement and injection advance angle at steady condition and their dynamic response to operating stability, accelerability and combustion process of the diesel engine.
