내연기관의 연소 최적제어용 디지탈 제어장치 구성

Abstract

적응제어수단과 점화각 기준표에 의한 開루우프 제어기법을 결합한 새로운 형태의 점화 시기 제어장치를 구성함에 의하여 연소의 최적화를 시도하였다. 구성이 단순하고 제어수단에 융통성이 있으므로 신뢰도, 적용범위 및 경제성에 있어 매우 유리하다고 판단되었으며 마이크로 컴퓨터를 중심으로 완전 전자회로화된 계통을 구성하였고 실험결과 이용 가능성과 함께 몇가지 개선의 필요성도 확인되었다.

Combustion potimization of an internal combustion engine was exmained using a new type of ignition timing controller which employs combined algorithm of adaptive and table-lookup open loop control strategy. The control strategy is implemented in a microprocessor-based all electronic control unit.

It has been found that the implementation was simple, and the control strategy flexible, thereby improving reliability, applicability and economy. the usefullness of the system has been proved through laboratory experiments on an engine test bed. Points to be improved for practical applications are also discussed.
