BūvTB004 [GBTRB004] Motor Vehicle Structure

Course abstract

The aim of the course is to acquire constructions and operation principles of ground motor vehicles. Gets knowledge about mechanisms and systems of internal combustion engines. Acquires mechanical and electronical regulation of mechanisms and systems of the engine. To be able to work independently and to understand engineering technical solutions of ground motor vehicle constructions. Acquires practical construction and operation of transmission, movement and control equipment of ground motor vehicles.

Learning outcomes and their assessment

Knowledge - peculiarities of vehicle construction, principles of operation of their units. Knowledge is assessed in tests. Test 1 - “Construction and operation of automobile engines” - in the form of a test, successful mark, if 70% of the questions are answered correctly. Test 2 - “Car transmission operation” - in the form of a test, successful mark, if 70% of the questions are answered correctly.
Skills - to evaluate the technical indicators of cars and engines, their operation. Skills are assessed in laboratory work.
Competence - to constantly analyze the engineering solutions of vehicle constructions, to constantly solve technical issues to ensure the failure-free operation of cars. Able to independently determine the technical condition of automotive structural elements.

Requirements for awarding credit points

Laboratory works have been developed and defended, tests are successfully written.

Description of the organization and tasks of students’ independent work

1. Searching for information on car safety systems, individual work is developed in PowerPoint and presented.

2. Analysis of laboratory works.

Criteria for Evaluating Learning Outcomes

The assessment of the study course exam depends on the cumulative assessment of the study course tests.
The exam grade is calculated as the arithmetic mean of the two exam assignments and the mean mark of the tests.
