2. 16. Simulation-Based Optimization of a Series Hydraulic Hybrid Vehicle

   Author : Katharina Baer; Petter Krus; Liselott Ericson; Seppo Tikkanen; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Hybrid transmissions are characterized by their utilization of more than one form of energy storage. They have the potential to help reduce overall fuel consumption and vehicle emissions by providing the possibility of brake energy recuperation and prime mover operation management. READ MORE

4. 17. 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).

   Abstract : The development towards higher specific power and lower displacement engines in recent years has placed increasingly high thermal loads on the internal combustion engine materials. Further, the advent of hybrid power trains placing higher demands on quick starts and a rapid approach to maximum power necessitates the automotive industry to move towards a more robust computational thermo-mechanical fatigue life prediction methodology to develop reliable engines and reduce developmental costs.
