4. 2. High Octane Number Fuels in Advanced Combustion Modes for Sustainable Transportation

   Author : Amir Bin Aziz; Förbränningsmotorer; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Octane number; Low temperature combustion LTC ; Ignition delay; Methanol; HCCI; PPC; Multiple injection strategy; φ-stratification;

   Abstract : The research community recently proposed a low-temperature combustion (LTC) concept that can simultaneously reduce Nitrogen Oxides (NOx) and soot emissions while maintaining high engine efficiency. Given that diesel fuel is prone to preignition with early injection, gasoline-like fuel with high octane number is utilised to provide sufficient ignition delay and extend the load range. READ MORE
