Course abstract

The aim of the course is to provide the students with theoretical and practical skills in determining the parameters of car operation. The calculations are based on the engine's external curves, speed, power and traction balance, acceleration and dynamic factors, running time and road schedules. The calculation methodology can also be used in the practical work of various engineering specialists of the transport sector.

Learning outcomes and their assessment

1. Knowledge - can do practical calculations according to selected automobile data and evaluate the automobile dynamic properties skillfully applying different calculation and evaluation methods - course work.
2. Skills - the students use the acquired theoretical basis and correlations for practical calculations of automobile exploitation parameters and comparison of different automobiles; they have skills in relation to selection of the most suitable automobile for exploitation - course work.

3. Competence - based on the calculation algorithms the students can evaluate and choose the most suitable kind of automobiles and calculate the necessary parameters that are needed for ensuring of optimal efficiency of automobile exploitation. Know the methods of calculating the performance parameters of the car - course work.
