電子點火控制系統參數最佳化對引擎性能影響之研究

本研究以引擎動態反應原理，透過硬體電路將引擎訊號處理為微控制器所需之判別訊號，經由微控制器進行引擎轉速計算、最佳點火角演算以及點火充電電壓之調整等相關參數，並將演算結果做一即時的反應做動；經由計算後電子點火角及電子點火電壓之相異所爆炸產生出一引擎動力，由此動力回授至微處理器進行最佳電子點火角的修正；並針對電子點火角對於引擎負載變化時做一電子點火角度的微調；最後再由一便利的點火曲線修改器針對電子點火控制系統進行電子點火曲線的快速調整，降低其設計者在測試時須做電子點火角之即時調整之不便利性以及縮短工程師在引擎開發試時的時間及研發費用，可大幅提升人員測試之效率。
