Course contents *
Repetition and practice on basic thermodynamics applied on combustion engines. Common idealised processes, turbo charging and charge air cooling are included. Fuel cell as a possible future process is treated.
The basics in combustion for diesel- and SI-engines are treated in lectures. In the same context, different fuels, basic chemistry and formation of emissions are included. Future fuel scenarios are discussed.
Small 2-stroke and 4-stroke engines for lawn movers and cars are shown and discussed in small groups around cut open engines and important components. Marine engines are treated in a lecture.
A modern car engine is disassembled and assembled by guided students in small groups with simultaneous explanation of function.
Practical exercises are given, where both a diesel- and an SI-engine are tested and emissions are measured. One of the exercises shall be documented by the participant and a number of thermodynamic calculations shall be done. As part of the report, the turbocharger efficiencies shall be calculated from the measured data.
The mechanical and dynamic forces for the piston movement are deduced and examples are calculated. Different cylinder arrangements and total vibrations are studied.
Ignition- and fuel- and control-systems are discussed. Lubrication systems, engine oils and cooling systems are treated.
