MEPP412
Automobile Engineering
3 Cr.
Course objective:
The course is aims to provide beginners in the automotive field with a thorough understanding of the construction and operating principles of the modern automobile.By stressing the fundamental of automotives theory, the course provides the students with the necessary background for intelligent diagnosis and repair. It also aims to train the students up-to-date methods of maintenance and repair of automobile, this course can serve as a means of upgrading the skills of that mechanical engineer in the automotive field and as encyclopedia of automotive information for those who wish to understand, maintain, and repair their own vehicles.
The objective of automobile engineering is to design, develop, manufacture, and maintain vehicles such as automobiles, trucks, motorcycles, and other forms of transportation. It encompasses a wide range of activities related to the design, production, testing, and improvement of vehicles and their components.

Assignments and class tests
There will be at least one tutorial for the each module, and all together they will count 30% of your internal marks. Tutorial sheet will be handed out to the students at the conclusion of the module.
Student will be provided with two class test and best one will be averaged to provide 70% of the internal marks. The class test schedules will be as notification of the Department of Mechanical Engineering with reference to university calendar. The class test duration is 60 minutes and the class test question may contain both objective and subjective types. The instructor can arrange additional class tests if needed.
