Course purpose

The course aims at providing fundamental knowledge of internal combustion engines. The principles that govern engine design and operation are presented, and it is shown how the operating characteristics, power, efficiency and emissions, depend on major engine design and operating conditions.

The course is a basic course in Internal Combustion Engines that provides the student with sufficient knowledge to take active part in design and development work within the automotive industry.

The course is primarily related to three global sustainability goals, namely:

    #3, good health and well-being, e.g. exhaust emissions

    #7, affordable and clean energy, e.g. efficiency and CO2

    #13, climate action, e.g. efficiency and CO2

 

Learning objectives and syllabus

Overall objectives

After the course the student should be able to

• Explain what torque, power and fuel efficiency of an internal combustion engine are (and to some extent of the entire powertrain), and to discuss how these properties change with load
• Describe and explain the major phenomena going on in an internal combustion engine such as gas exchange, combustion and emissions formation/reduction.
• Reflect on the role of internal combustion engines for transports in society as well as the emissions issue from both a sustainable and ethical perspective.

Examination form

Midterm Saturday 21 September – 8.30-10.30, SB/V building (midterm rules, see the end of this document).

Examination at the end of the course, time and place see Student portal. The examination consists of two parts, a theoretical and, for those who did not pass the midterm, a calculation part. No help (books etc.) are permitted for the theoretical part, for the calculation part a text book (Stone or Heywood) and an accepted calculator may be used.

Only students who have handed in the assignments and who have completed the laboratory work may be examined.

 

Midterm and Exam “rules”

(MTF240 Internal Combustion Engines)

 

The midterm takes place

Saturday 21 September 2019, kl 8.30 – 10.30,

As aid you may use pen and paper, an accepted calculator (by Chalmers or the examiner), and one textbook.

To pass the midterm 7 points is needed (15 points is maximum).
If you obtain 9 (9-11.5) points you will get two bonus points for the final exam.
If you obtain 12 (12-15) points at the midterm you get 5 points to use in a similar manner.

If you pass the midterm you do not have to do the problem (calculation) part of the exam. However, the bonus points of this midterm may be used in the course only for one year, i.e. until August 2020, you cannot save your points to an exam after that.

If you do not pass the midterm you have to pass the calculation part of the exam, i.e. 40 % of the available points (6 out of 15 points). There is only pass/fail grading of this part, the grade of the exam is giv en by the result of the theoretical part with pass (grade 3) at 40 % (16-23.5 points), grade 4 at 60 % (24-31.5 points), and grade 5 at 80 % (32 points and more). The grade is based on the sum of the exam points and the bonus points from the midterm. You can use your bonus points to increase your result only if you have passed the exam, i.e. the bonus points can only be used to go from grade 3 to 4 or 4 to 5, not as a help to pass the exam

You only have to pass the calculation part (midterm or exam) once in order to pass this part of the examination.
