Course detail

Semester Project

FSI-QS3 Acad. year: 2019/2020 Summer semester

This course enables students to acquire the desirable habits of independent design work, with special focus upon the piston combustion engines. Lectures serve to communicate the concept and the procedures related to planning the essential dimensions of an engine. The draft of dimensions of basic engine parts and a preliminary calculation for assessing the preliminary strength. Seminars help to work out a computerized protocol of the basic project parameters of an engine and a corresponding drawing documentation of selected engine parts.

Learning outcomes of the course unit

This course makes students familiar with complex improvement findings of the branch when designing a piston internal combustion engine.

Prerequisites

Design of machine parts, kinematics and dynamics of machine mechanism, evaluation of these elements regarding mechanics and elasticity and strength. Thermo cycles of combustion engines and thermal load. Combustion engines maps.

Planned learning activities and teaching methods

The course is taught through lectures explaining the basic principles and theory of the discipline. Exercises are focused on practical topics presented in lectures.

Assesment methods and criteria linked to learning outcomes

Graded course-unit credit requirements: a presentation in seminars and submitting a calculation protocol and drawing documentation. Final evaluation consists of: corectness of calculation and elaboration of drawing and graphic layout of the submitted materials.

Aims

The aim of the course is to practise the collation of theoretical findings, which students learned in other courses.

Specification of controlled education, way of implementation and compensation for absences

Attendance in seminars is obligatory, checked by a teacher. The way of compensation of an absence is solved individually with a subject provider.
