燃料節約과 排氣가스 減縮을 爲한 電子式 엔진制御

Abstract

小型 내연기관의 燃燒 최적화를 爲한 새로운 형태의 제어장치를 構成하여 試驗하였다. 이 시스템은 미리 수집된 중요 동작점에서의 제어변?嗤? 기억장치에 기억시키고 實時間 상황에서 制御變數가 그 값을 벗어나지 않는 범위 안에서 適應制御則을 따르도록 한 microprocessor를 주요소로 하는 全電子式 點火時間 제어장치로서 構成이 간단하고 제어측에 융통성이 있어 몇가지 問題點만 해소된다면 實用性 있는 시스템이 될 수 있겠다는 것을 試驗用 엔진에서 行한 實驗을 通하여 確認하였으며 實用化를 爲한 問題點들을 檢討하고 改善方案을 제안하였다.

A new type of self-tuning electronic engine control system for a small I. C. engine was developed and tested for combustion optimization. The system employs combined algorithm of adaptive and table look-up open loop control strategy implemented on a microprocessor based all electronic ignition timing control unit.

It was found that the implementation was simple, the control strategy flexible, and the system may prove to be practical if some of the partinent problems are removed.

The usefullness of the system has been tested through the labortory experiment performed on an engine test bed. Points to be improved for practical application of the system are also discussed.
