Automotive engineers and technicians are employed in a variety of activities, such as motor car, truck, bus, military and emergency services vehicle maintenance and repair, roadside breakdown services, insurance assessors, and vehicle inspectors. In the UK, there are around 230,000 motor technicians. They all need a firm grasp of science and technology in order to fully appreciate and understand how mechanisms and systems of modern vehicles work, which is reflected in the vocational training programmes, such as the BTEC First and National and the IMI courses. Unlike general engineering mathematics and science books, this textbook presents the necessary principles and applications with all the examples and exercises relating directly to motor vehicle technology and repair, making it easy for automotive students and apprentices to relate the theory back to their working practice. It will also prove a good introductory text for any automotive students on Higher National and Foundation degree courses in Automotive Engineering.
