Vehicle Components and Systems II

At the level of mechanical technology, general mechanics, chemistry and electricity and electronics.

In theoretical classes, a theoretical exposition of each subject is made.

In theoretical-practical classes, engine components and systems are identified and the resolution of theoretical-practical exercises is carried out.

In the laboratory component, specialized practical work is carried out.

To know the constitution, operation, technologies and manufacturing processes of vehicles and describe the types of bodies based on structure and shape.
To know car painting practices.
To know the theoretical and practical aspects of the operation and design of the different electrical and electronic systems used in the motor vehicle.
To perform disassembly, diagnosis, control, regulation, repair, assembly and replacement of elements that make up the electrical and electronic systems.
