2. 1. Advancing the Limits of Dual Fuel Combustion

   Author : Fredrik Königsson; Hans-Erik Ångström; Arne Andersson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel Dual Fuel; Methane; CNG; Biogas; Injector; Coking; Knock; Pre-ignition; Preignition; HCCI; PPCI; PPC; RCCI;

   Abstract : There is a growing interest in alternative transport fuels. There are two underlying reasons for this interest; the desire to decrease the environmental impact of transports and the need to compensate for the declining availability of petroleum. In the light of both these factors the Diesel Dual Fuel, DDF, engine is an attractive concept. READ MORE

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
