This study developed the knocking analysis algorithms for fuel redection applicable to the ECU exclusive to the industrial CRDI engine in order to meet the enhanced emission standards. In order to develop algorithms to determine diesel knocking using the operating principles of CKP and CMP among the input elements of CRDI engine control ECU. The development of the algorithms has enabled to adjust fuel injection timing and amount. Thus, this study aims to improve engine efficiency and to reduce emissions.
