A Simplified Prediction Model of Engine Warm-up for Heavy-duty Diesel Engines
簡易的なモデルによる重量車搭載ディーゼルエンジンの暖機過程予測手法
Predicting an engine warm-up process is effective for evaluating fuel consumption and exhaust emissions in the cold start condition with the vehicle simulation and on-board diagnosis of a coolant temperature sensor used for engine control. In this study, a prediction method of coolant temperature in the engine warm-up process was developed by using a simple calculation model and quantified total heat mass of the engine system based on experimental data. In addition, the method was validated under various conditions by an engine test cell and a vehicle test cell experiments.エンジンの暖機過程を予測することは，冷機始動時における燃費・排出ガス性能等のシミュレーションや，エンジン水温センサ異常時の制御機能の維持に有効である．本研究では，簡易的なモデルと実験的に定量化したエンジンシステムの総熱容量を用いて，暖機過程におけるエンジン水温の変化を予測する手法を構築した．
