轉子引擎控制系統整合與平台測試
Integration and Bench Testing of an Engine Control System on a Rotor Engine
摘要
本論文主要是針對一具轉子引擎做引擎控制系統(Engine Control system, ECS)的整合以及實際平台的運轉測試，該引擎為中科院在無人飛行載具(Unmanned Aviation Vehicle, UAV)動力系統研發之RU200引擎。所使用的引擎控制系統是由Ecotrons公司所開發，取代原本的引擎控制系統及其周邊系統，並建置平台以測試能否達到期望之運作狀況。 引擎控制系統所需整合的部分包括：引擎控制單元、進氣系統、供油系統、點火系統以及排氣系統等。在硬體方面，現有RU200轉子引擎必須做適當地加工修改，以使Ecotrons公司所提供之相關元件能適當地安裝。主要加工修改工作有：節氣門體與進氣口空氣濾清器之間連接座的重新設計與裝配、進氣岐管的加工裝配、引擎溫度感知器與引擎本體的匹配安裝。此外供油系統與點火系統可直接取代安裝。而排氣系統方面，則與舊有系統一樣省略含氧感知器的回饋控制。 在軟體方面，Ecotrons的引擎監控軟體稱為EcoCAL，在控制程式架構上，新增轉子溫度感知器的輸入處理；而程式的調校則藉由平台測試完成，測試分成靜態測試與動態測試，靜態測試主要做各感知器輸入參數特性曲線的修改匹配，動態測試上主要是針對程式裡各特徵圖的調校，本論文主要完成了靜態測試部分，顯示Ecotrons之引擎控制系統可以整合至此轉子引擎，預期將可成功地完成引擎最後動態測試以及性能最佳化的調校。

In this paper, an engine control system is integrated into the rotary engine and performed an operation test on the test platform. This rotary engine is the RU200 engine developed by the Chung-Shan Institute of Science for the Unmanned Aviation Vehicle (UAV) . The original engine control system (ECS) and related subsystems are replaced by those developed by Ecotrons company, and the testing platform is built to achieve the desired operation. The subsystems of the engine control system required integration into engine control unit (ECU) include the air system, fuel system, ignition system and exhaust system. For hardware, the RU200 engine must be properly processed as the related components of Ecotrons are installed. The main modifications are ; 1) design and modification of the connection between the throttle body and the air cleaner; 2) design and installation of the Intake manifold; 3) fitting of the engine temperature sensor into the engine body. In addition, the fuel system and ignition system can be directly utilized without replacement. As for the exhaust system, the feedback control of O2 sensor is omitted. For software, the engine monitoring program of Ecotrons is called EcoCal. In control architecture, the signal of the rotor temperature sensor is newly added for an input. The program calibration is completed on a test platform. The tests are divided into the static tests and the dynamic tests. The static test is mainly focused on tuning the sensor inputs for the control program. Dynamic test is mainly performing the calibration of the characteristics map in the program. In this paper, the static tests are completed, and some preliminary dynamic tests are fulfilled, confirming that the engine control system of Ecotrons can be well integrated into the rotor engine. In the future, the complete dynamic tests and performance tuning is expected to be successfully achieved.
