1. A Detailed Modeling Study for Primary Reference Fuels and Fuel Mixtures and Their Use in Engineering Applications
Abstract : The aim of this work is to generate detailed and simplified kinetic models for the oxidation of the Primary Reference Fuels (PRF) n-heptane, iso-octane and their mixtures, with low numbers of species and reactions. These mechanisms are consistent in terms of the choice of kinetic parameters for the different reaction classes. READ MORE

2. Impact of Fuel Properties on Partially Premixed Combustion
Abstract : Compression ignited engines generally have higher efficiency than spark ignition engines. However, the most common combustion concept in compression ignited engines, conventional diesel combustion, struggles with high levels of particulate matter and NOx emissions. READ MORE

4. Discribing the Auto-Ignition Quality of Fuels in HCCI Engines
Abstract : The Homogeneous Charge Compression Ignition (HCCI) engine is a promising engine concept that emits low concentrations of NOx and particulates and still has a high efficiency. Since the charge is auto-ignited, the auto-ignition quality of the fuel is of major importance. READ MORE
