The combustion engine is a complex machine with many different processes and phenomena. This course has the aim to look more in detail on some of these processes and gain a deeper understanding of them.

The course is organized as a series of seminars where each time one of the students is responsible for presenting and discussing a chapter in the course book. The students are also responsible for looking up up-to-date information in the literature to complement the information in the course book. The discussion is documented by another student and the documentation is subsequently distributed to all the students. The presenting student is also responsible for designing exam questions on the subject of the chapter/seminar.

The course covers
Engine types and their operation
Engine design and operating parameters
Thermochemistry of fuel-air mixtures
Properties of working fluids
Ideal models of engine cycles
Gas exchange processes
SI engine fuel meeting and manifold phenomena
Charge motion within the cylinder
Combustion in spark ignition engines
Combustion in compression ignition engines
Pollutant formation and control
Engine heat transfer
Engine friction and lubrication
Modeling real engine flow and combustion processes
Engine operating characteristics

Know the basic engine types and their typical applications
Understand the concepts of mean effective pressures and be able to use them
Know the difference between real and ideal gases and how it influences engine cycles
Know the parameters that influence the gas exchange of an internal combustion engine
Know how swirl is measured and concepts for promoting it
Know the definitions of turbulence and how it is measured in an engine
Understand the use of dimensionless numbers like Damköhler and Reynolds numbers and how they affect the combustion in spark ignition engines
Understand knock
Understand the difference between the compression ignition combustion model proposed by Heywood and the current "truth" by Dec
Understand why and how NOx is formed in spark ignition and compression ignition engines respectively
Know the formation process of HC, CO and PM and how aftertreatment can be used to clean the exhaust
Know the most widely used heat transfer correlations and how to use them
Understand the importance of friction and where in the engine friction is a problem
Have a basic understanding of what models can be used for various processes in the engine
Understand the differences between 1D and 3D models
Understand how engine operating conditions influence the engine performance and analysis

Be able to find and use the properties of fluids within the cycle
Know the basic design of valve systems and be able to design such a system

Within a limited given time frame, be able to study a subject within the combustion engine field and present it to fellow PhD students and lead a discussion such that the subject is thoroughly penetrated
Be able to select/design suitable exercises on the subject that the student has been responsible for during the course
Be able to design suitable examination questions on the subject that the student has been responsible for during the course
