Theory of Energy Transformation, Power Units (FSI-QTS)

Academic year 2023/2024
Supervisor: prof. Ing. Josef Štětina, Ph.D.  
Supervising institute: ÚADI all courses guaranted by this institute
Teaching language: Czech
Aims of the course unit:

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

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.
Prerequisites:

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.

Links to other subjects:
compulsory co-requisite: Tractors [QT]
Course contents:

The course introduces students to the theory of propulsion units with a focus on the thermodynamics of working cycles, combustion, and heat transfer. The theory of energy transformation is included.
Teaching methods and criteria:

The course is taught in the form of lectures, which are in the nature of an explanation of the basic principles and theory of the discipline. The teaching is supplemented by laboratory and computer exercises.
Assesment methods and criteria linked to learning outcomes:

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.
Controlled participation in lessons:

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.
Type of course unit:
    Lecture  13 × 3 hrs. optionally                  
    Laboratory exercise  10 × 2 hrs. compulsory                  
    Computer-assisted exercise  3 × 2 hrs. compulsory
