摘要: 
目前國內市售機車使用的燃油噴射系統主要為外購,其ECU內部的空燃比控制演算法無法由機車製造商進行修改,提升控制性能。隨著排放標準逐年加嚴的情況下,現行市售噴射機車引擎在空燃比控制上已經愈來愈難以符合法令要求。
為提升國內燃油噴射控制科技,本研究以一具50cc單缸四行程機車引擎為研究對象,並自行研製ECU,載入控制策略進行空燃比控制。在ECU硬體部份,本研究以市售容易取得之8051系列晶片,搭配類比數位轉換器與感知器周邊電路,自行研製符合機車使用的ECU;在ECU軟體部份,則以ANSI C語言,發展燃油噴射系統控制程式。
而在空燃比的控制策略部份,主要使用汽車上已發展成熟的速度密度法與傳統3D-MAP兩者為基礎,搭配廣域含氧感知器信號量測空燃比控制結果,並以PI控制為基礎建立回饋控制。本研究以無負載、有負載兩種不同運轉情況進行測試,並以ITAE/IAE比較不同PI增益組合之間的控制性能差異。

In Taiwan, most commercial EFI system of motorcycle's engines use the general ECU systems that provide by outsourcing, manufacturers cannot change the air-fuel control algorithm in case of their own engines. However, as Taiwan government promulgated the new emission standard, currently air-fuel ratio control performance of general ECU system is difficult to meet the issue.

This research built an electronic fuel injection system by commercial motorcycle sensors, fuel injector, and throttle body. An NTK UEGO sensor was used to measure air-fuel ratio. In order to implement the control algorithm for stoichiometric air-fuel ratio control, an ECU module has developed. The ECU module is build by some commercial IC chips, and the control algorithm is implemented by ANSI C.

In this research, control algorithm consisted of feed-forward control and feedback control. Both speed-density method and traditional 3D-MAP are applied in feed-forward control. In feedback control algorithm, this research uses traditional PI control because of the restriction on micro-controller computing performance.

The control algorithm is valid on engine dynamometer. In order to compare the performance with different control algorithms and engine operation conditions, ITAE is applied as performance index. Besides, IAE is applied to compare the different gain of feedback control during transient engine operation.
