Automobile Repairs and Engineering combine experience and knowledge of mechanical, electronic, fuel and computer systems to inspect, maintain and repair engines and related components in all states of disrepair. Motivated by the challenge of diagnosing the problem, automotive engineers and technicians rely on their senses and computerized testing to find problems. Customer service skills are essential, as many clients are negatively impacted by a car or truck that isn't working and in dire need of fast, flexible, effective service. Knowledge of electric power systems and alternative fuels is a relatively new equirement for automotive mechanics and technicians. As new diagnostic and engineering technologies continue to emerge, mechanics must stay up-to-date in order to meet the needs of their customers. A programme in automotive engineering, which includes engine repair and maintenance, is therefore imperative for the industry.
