Titre : Sensitivity analysis of combustion timing of homogeneous charge compression ignition gasoline engines Type de document : texte imprimé Auteurs : Chia-Jui Chiang, Auteur ; Stefanopoulou, Anna G., Auteur Année de publication : 2009 Article en page(s) : 05 p. Note générale : dynamic systems Langues : Anglais (eng) Mots-clés : temperature;  combustion;  fuels;  engines;  cylinders;  exhaust  systems;  sensitivity  analysis;  gasoline  engines;  homogeneous  charge  compression  ignition  engines Résumé : The goal of this paper is to identify the dominant factors that should be included in a control oriented model in order to predict the start of combustion in a homogeneous charge compression ignition (HCCI) engine. Qualitative and quantitative information on the individual effects of fuel and exhaust gas recirculation on the HCCI combustion is provided. Using sensitivity analysis around a wide range of operating conditions of a single-cylinder port-injection gasoline HCCI engine, we find that temperature is the dominant factor in determining the start of combustion. Charge temperature thus becomes the “spark” in a HCCI engine. Therefore, a model without the composition terms should be adequate for model based regulation of the combustion timing in a port-injection gasoline HCCI engine with high dilution from the exhaust.
