Aim

The objective of the course is to provide a deeper understanding of the design of modern internal combustion engines as well as on advanced engine concepts and methods.

Learning outcomes

Knowledge and understanding
For a passing grade the student must

• be able to provide an individual written account for the design of advanced Otto and Dieseltype engines and assess the strengths and weaknesses
• be able to provide an individual written account for alternative engine concepts such as HCCI and PPC in relation to conventional concepts
• be able to provide an individual written account on various fuels impact on engine performance and emissions
• be able to in written account for engine control strategies, engine measurement methods as well as engine heat transfer processes

Competences and skills
For a passing grade the 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 measurements
• 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 student must

• actively participate in discussions of relevant problems for the subject
• be able to present written analysis of combustion engine measurements and/or simulations

Contents

The course starts with an in-cylinder pressure analysis for heat release evaluation. Modern and advanced Otto and Dieseltype engines are investigated as well as the histrorical development of engines. Advanced gasexchange systems are discussed and special emphasis is provided on direct fuel injection since such systems have evolved dramatically the last years. New types of internal combustion engines such as HCCI and PPC are explained. Measuring techniques for the analyzing of engines as well as engine control are presented. Fuel aspects with emphasis on engine perfomrance and emissions is presented. Engine heat transfer processes and Waste Heat Recovery are explained. Finally an introduction to engine modelling is given.

Laboratory work will be given in which PPC is analyzed. Computer projects will also be conducted with the purpose of making the students identifying engine components as well as running engines virtually.

Normally a guest lecture will be given y an expert from industry.

Examination details

Grading scale: TH - (U,3,4,5) - (Fail, Three, Four, Five)
Assessment: Written examination graded with Fail or one of the passing grades 3, 4 or 5 which normally correspond to 40, 60 and 80% of the maximum number of points respectively. In order to qualify for participation in the written examination all of the mandatory laboratory exercises must have been completed with approved reports.

The examiner, in consultation with Disability Support Services, may deviate from the regular form of examination in order to provide a permanently disabled student with a form of examination equivalent to that of a student without a disability.
