2. 1. Computational Analysis of Heat Transfer and Fluid Flow with Relevance for IC-Engine Cooling

   Author : Sassan Etemad; Värmeöverföring; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Termisk teknik; termodynamik; turbulence models; Heat transfer; curved duct; secondary flow; IC-engine cooling; Gases; Thermal engineering; applied thermodynamics; Teknik; Technological sciences; plasma; Gaser; fluiddynamik; plasmas; fluid dynamics;

   Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE

4. 2. IC-engine intake noise predictions based on linear acoustics

   Author : Magnus Knutsson; Mats Åbom; Antonio Torregrosa; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

   Abstract : Shorter product development cycles, densely packed engine compartments and intensified noise legislation increase the need for accurate predictions of IC-engine air intake noise at early stages. The urgent focus on the increasing CO2 emissions and the efficiency of IC-engines, as well as new techniques such as homogeneous charge compression ignition (HCCI) might worsen the noise situation.

5. 3. Towards High Efficiency Powertrains

   Author : Jayesh Khatri; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hybrid powertrain; water injection; Downsized spark-ignition engines; RON; efficient engine starts; knock mitigation; warm engine starts;

   Abstract : In recent years there has been a great shift whereby conventional vehicles powered by an internal combustion (IC) engine are being partially or completely replaced by electrified alternatives; almost all major automotive manufacturers have made statements indicating a shift towards electrification. This shift has been driven in large part by concerns about climate change, which have prompted lawmakers to introduce increasingly strict regulations limiting vehicular emissions, particularly of carbon dioxide (CO2).
