Optimization Calibration of Engine Ignition Advance Angle Based on Engine Model

Abstract:

Based on the mean-value theorem of the engine, the mathematical models can be created for the four-stoke-cycle-CNG engine, style of YN30QNE. Furthermore, while the mean-value models set the basis for the external loading resistance model controller, the adjust-dimention-burning engine models give birth to the models, as well as the MAP figures, of the engines controlling of the advance angle of ignition. Finally what the tests show us are as follows. Firstly the advance angle of ignition does the same, as the rotating velocity increases, and on the condition of the same rotating velocity, the best suited advanced angle of ignition decreases reversely with the growing loading resistance of the engine. Secondly it not only brings us the rarely precise original MAP figures of the advance angle of ignition, but also shortens the development cycle. Lastly, in the process of the calibration, optimal functions are used to conduct the PID optimal designing for the external loading resistance controller, which makes the system converge faster, improves the efficiency of the calibration as well as optimizes the results of the calibration.
