Institute of Automotive Engineering

Entry knowledge

Prerequisites and co-requisites The student must have knowledge corresponding to subjects of theoretical basis of bachelor study in the field of engineering education, especially thermodynamics and Heat Transfer.

Rules for evaluation and completion of the course

The credit is conditional on active participation in the exercises, proper preparation of the elaborations and fulfilling the conditions of any control test. The examination verifies the knowledge acquired in lectures and exercises, is written, including a test in e-learning, and may have an oral part verifying knowledge after the written part.


Classes are compulsory, attendance is checked by the teacher. The form of substitution of lessons missed for serious reasons and in exceptional cases is solved individually with the course supervisor.

Aims

To provide knowledge for practical and theoretical, experimental and scientific activities in the field of power units, especially for motor vehicles.


Students learn individual concepts from the theory of power units, get acquainted with basic systems of power units, determination of their characteristic dimensions, and gain knowledge of computational models of these systems.
