Abstract

This paper presents the validation results of TNO's combustion model designed to support RCCI control development. In-depth validation was performed on a multi-cylinder heavy-duty engine operating in RCCI mode on natural gas and diesel fuel. It was shown that the adopted approach is able to represent experimental pressure trace with the accuracy within cycle-to-cycle variations at low to mid-range engine loads. The highest load case showed slightly higher deviation. The modeled emissions remained at similar levels as exhaust manifold sampling results (except for NOx which was under-predicted). Furthermore, performance indicators such as IMEP and CA50 showed good agreement with measured values.
