Course-PM

MTF 242 Internal combustion engine, advanced course lp3 VT22 (7.5 hp)

Course is offered by the department of Mechanics and Maritime Sciences

Aim of course

The course aims at providing deepened knowledge of internal combustion engines. This course will be a continuation of the ICE introduction in the Introduction to Propulsion course and will include laboratory (engine dismantling and engine dyno-lab) and simulation assignments (heat-release and 0D gas-exchange). The principles that govern engine design and operation are complemented and more thoroughly discussed as fundamental ICE knowledge but also for state-of-the-art and future applications.

The course provides the student with sufficient knowledge to take active part in ICE design and development work within the automotive industry. 

The course is primarily related to three global sustainability goals, namely:

     #3, good health and well-being, e.g. exhaust emissions

    #7, affordable and clean energy, e.g. efficiency and CO2

    #13, climate action, e.g. efficiency and CO2, renewable fuels.
