Course main content

The course covers combustion, exhaust emission formation and control of exhaust emissions of spark ignition and diesel engines. It covers inertia forces and two-stroke engines. Training in oral and written presentation are included. The course builds on the content of the ICE 1 and is a continuation of this.

Disposition

Combustion and formation of emissions in diesel, SI-engines and alternative combustion schemes are treated in lectures. This is followed up by laboratory exercise with combustion analyses. Laboratory exercises with measurements similar to certification illustrate the emission problem. Control systems are important for optimisation of performance and emissions. This is illustrated in lecture and laboratory exercise.

Aftertreatment systems including catalysts, SCR and particulate filters are discussed.

Ship engines are treated in lectures.

Crank mechanism kinetics is deduced directed towards 1st and 2nd order vibrations. Vibrations including torsional vibrations are treated with related mathematical problems trained.

Thermodynamic cycle calculations are performed with world leading commercial software. The computer exercises are done during scheduled time with support from instructors. The computer exercises have objectives to learn how gas exchange gas dynamics and turbocharging can be optimized for a performance target. The pulsative nature of the gas dynamics is highligted.

Engine design, material choice and production methods are treated.

Industry tours are made to study product development and engine production.

Each student chooses a subject to be presented for about 20 minutes during a randomly chosen lecture time. A lecture in presentation technique is included.
