Internal Combustion Engines - New Techonologies

To know the operation of all systems that integrate the internal combustion engines, as well as to know how to make the respective diagnosis of symptoms and application of maintenance techniques.

a) Theoretical-practical: consist of exposure by the teacher of the syllabus, using audiovisual media.

b) Practices: the different technologies are analyzed, research by students on the various themes and reports are developed, in groups of students, with the support of the teacher.

Knowledge and skills: a.1 Understand and know how to integrate technological innovations in order to facilitate the easy integration of graduates into the job market. a.2 Ability to identify, analyze and solve problems with new engine technologies (NTM) used in automotive traction, as well as to build and support new engine diagnostic and preparation solutions. a.3 Ability to collect, select and interpret information to support the recommended solutions. a.4 Ability to interpret experimental results and develop experiences implementing NTM.

Competences: b.1 Know how to perform measurements, instrument and control the operation, in engines of new technologies. b.2 Have the ability to install, operate and maintain and repair under NTM. b.3 Know how to apply fault detection technologies to vehicles with NTM.

In this unit, the periodic assessment methodology is applied, with the following characteristics:
1) Preparation and discussion of an individual work/report (exceptionally 2 students), written in PowerPoint format, vertical page, using Times New Roman font, size 24, with 12 to 15 useful lines per slide and with a minimum 25-30 useful slides*number of students in the group, with full pages of descriptive text. The report must include a chapter written in Portuguese and English on the maintenance of equipment associated with the new technology studied. The number of 25-30 useful slides*number of students in the group, does not include the cover, index, bibliographical references, nor the English translation of the chapter on maintenance. The bibliography must mention at least 2 books or 2 scientific articles published in a journal. The report will be delivered to the teacher by the end of April.. The analysis and discussion of the reports will take place throughout what remains until the end of the semester. This assessment component contributes 50% to the final grade, on a scale of 0 to 20.
2) Exam, which is carried out during official examination periods. This will have a maximum duration of 2 hours, with 15 questions covering the entire subject, of which 5 questions are descriptive, with a score of 10 points, and 10 questions are multiple choice, also with a score of 10 points. This component contributes 50% to the formation of the final classification, on a scale of 0 to 20 points.
Multiple choice questions answered incorrectly by students will be discounted by one third of the score (up to -0.3334 points).
There may be multiple choice questions with more than one correct statement.
Only students who attend at least 50% of all classes, can to be approved in the Unit.

NOTES:
1-The student's approval is subject to the following requirements being met:
1.1. Have achieved a minimum of 8 points in the final exam grade.
1.2. Average score of no less than 9 points, on a scale of 0-20 points, in the component relating to the preparation, presentation and discussion of the work/report.
2-Gradings of laboratory work and/or reports of a theoretical, theoretical-practical or practical nature, relating to the current academic year, will not be accepted or counted in subsequent academic years.
3-When failure is due to not having reached the minimum defined for passing the final exam or periodic assessment, the acronym NRC (Does not meet conditions) is recorded on the agenda.
