Aim

The objectives of the course are, starting from the challenges for current internal combustion engines (ICEs), to present ways to improve ICEs, advanced concepts and alternatives; and provide the tools for investigating them

Goals

Knowledge and Understanding

For a passing grade the doctoral student must

• Be able to explain the design of advanced Otto and Diesel type engines and how to assess their strengths and weaknesses.
• Be able to explain the reasoning behind alternative engine concepts and fuels, and the challenges to overcome for them to make it to the market.

Competences and Skills

For a passing grade the doctoral student must

• Be able to use commercial computer software for gas exchange simulation of combustion engines.
• Be able to perform heat release analysis based on cylinder pressure data.
• Be able to, groupwise with supervision, conduct measurement of cylinder pressure as function of crank angle on a laboratory combustion engine.

Judgement and Approach

For a passing grade the doctoral student must Be able to assess an alternative engine design, control or fuel, for its strengths and weaknesses.

Course Contents

The course starts from the challenges facing current internal combustion engines. The historical development of engines is reviewed to better understand the reasons for current engine designs. Next, experimental and numerical tools are reviewed for investigating the processes occurring in engines, which are used in studying and improving engine designs. Advanced engine concepts and fuels are then discussed, with their merits and challenges. This includes advanced engine controls. Finally, an outlook is given as to where continued research and development of engines and fuels can lead, and how the combustion engine can be part of a sustainable future. Engine combustion will be analyzed in laboratory exercises. Simulation exercises will also be conducted with the purpose of making the students identify the engine’s response to changes to its components and settings as well as running engines virtually.
