  1. 1. A Methodology for the Design of Cost Effective Hybrid Vehicles

    Author : Jonas Hellgren; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuzzy logic; system engineering; model car; optimal design; evolutionary algorithms; hybrid electric vehicle; alternative powertrain; simulation; modeling; genetic algorithms; fuel cell vehicle; hybrid vehicle;

    Abstract : This thesis deals with system design of cost effective hybrid and fuel cell vehicles. Today (2004) the major disadvantages of these vehicles are increased complexity and component costs. However, the decrease in cost of electrical components and the environmental concern make these vehicles more and more competitive. READ MORE

  2. 2. Spark Ignition Combustion of Direct Injected Alternative Fuels

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Lars Christian Riis Johansen; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spark ignition; optical diagnostics; internal combustion engine; stratified combustion;

    Abstract : Several technologies and modifications exist to increase the fuel efficiency of passenger vehicles in general and spark ignition engines in particular. Combining a spark ignition engine with an electric drive system in hybrid powertrain and thermodynamic cycle improvements are two such approaches with the potential to greatly reduce fuel consumption.

  3. 3. The role of methane and hydrogen in a fossil-free Swedish transport sector

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Mårten Larsson; Per Alvfors; Stefan Grönkvist; Max Åhman; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; renewable transport fuels; biogas; methane; hydrogen; electrofuels; pyrolysis; well to wheel; transport policy; energy policy; Chemical Engineering; Kemiteknik;

    Abstract : Drastic reductions of greenhouse gas emissions are required to limit the severe risks associated with a changing climate. One measure is to disrupt the fossil-fuel dependency in the transport sector, but it appears difficult and costly in comparison to other measures. READ MORE

  4. 4. Evaluation of Gasoline PPC in a Multi-cylinder Engine : Capabilities & Challenges

    Abstract : Internal combustion engines have been the most used engine design when it comes to vehicle propulsion and transportation. But as the number of vehicles increase, new problems arise as well. READ MORE

  5. 5. Modeling, Optimization and Analysis of Electromobility Systems

    University dissertation from Department of Biomedical Engineering, Lund university

    Author : Gabriel Domingues; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electromobility; Electric Vehicles; Hybrid Vehicles; Charging; Modeling; Optimization;

    Abstract : Due to an increase in environmental awareness and an improved understanding on the impact of human activity on our planet’s climate, there is a strong desire both from governments and the general public to reduce harmful pollution and emissions. This requires action on different fronts, like decarbonizing electricity generation, industrial activity and not least the transport sector. READ MORE
