Project Description and Objectives

Combustion provides over 85% global primary energy supply nowadays. Clean combustion is one of the most important approaches to achieve environmental-friendly energy supply. To reduce the air pollutants in combustion, many novel combustion concepts have been proposed, where chemistry plays a crucial role and should be thoroughly understood. In this study, the chemistry in low-temperature combustion (LTC), which is a novel combustion concept to reduce both NOx and PM emissions in engine combustion, will be investigated with advanced experimental approaches. Key elementary LTC reactions will be investigated using a newly designed shock tube over a wide range of pressures and temperatures. A flow reactor and a jet-stirred reactor combined with mass spectrometry (MS), gas chromatography (GC) and GC×GC technique will be used to understand the secrets in LTC engine-relevant conditions. Kinetic models for the investigated fuel will be developed and validated based on the experimental findings. The outcome from these studies will be used to explore strategies for the control of combustion pollutant emissions in a more intelligent way.
