This course aims at introducing the students to the basics of automobile systems with main emphasis on the engine system. It teaches the student to analyze the engine performance and study its characteristics. Types of fuels, combustion and pollution. Then the design of fuel feeding systems and cooling system. The course also includes an experimental part which allows the student to estimate the performance of both spark ignition and compression ignition engines, effect of some parameters on engine performance like ignition timing, Air/Fuel ratio, Compression ratio and perform an energy balance of the compression ignition engine.
