Języki publikacji EN
EN The general IMO procedure was adopted with the main aim to achieve compliant engine performance with current environmental legislation. The paper investigates possibility of multi-zone diesel combustion model use to estimate NOx emission. The model calculation results are compared with the experimental data obtained for marine diesel engine - Sulzer A20/24. An experimental study is conducted to investigate the use of phenomenological multizone model to predict NOx emission, based on marine diesel engine operation parameters. The predicted and experimental results comparison shows reasonable agreement only within high engine loads, while serious discrepancies were found in low range operating effective power.
