A motor vehicle technician has to attain high technological skills to enable him or her to diagnose faults and service transport vehicles and their components. Science is a branch of study concerned with the systematic investigation of observed facts, and forms an important foundation on which to build sound engineering practice. Such a background will stimulate personal development by increasing confidence and intellectual ability. This is the second of two books which have been planned to cover the TEe U77/413 and 415 Motor Vehicle Science II and III Model programmes of study. Part 2 covers the requirements of Motor Vehicle Science III. The fundamental principles of engineering science have been applied to the motor vehicle in a systematic and progressive manner to enable the reader to follow most of the work on his or her own initiative. Emphasis has again been placed on the provision of many fully worked examples, some having more than one method of solution. These together with alarge number of exercise examples enable the student to improve subject knowledge and gain that vital confidence so necessary for examinations. The book is aimed mainly at the student who is attending a recognized college course leading to full Technician qualification. It is designed to become a valid source of information to assist the student both in and out of the classroom environment, but the importance of the college lecturer and his or her individual method of teaching the subject remains of prime importance to the student.
