Development of a Rule-based Calibration Method for Diesel Engines

An alternative calibration logic for engine control maps of the modern diesel engine has been developed for efficient engine calibration. This logic consists of both a fuzzy rule-based calibration and numerical optimization with DoE, (design of Experiments). This logic reduced more than 50% of calibration time against DoE. In this paper, we describe the concept and performance of the logic in detail. Especially, the details of the calibration algorithm are described.
