Unit Code: DAU502

Unit Name: Automotive Engine Technology

Description: The unit is designed to teach the students fundamental concepts and applications of engine technology, engine fuels, and its related combustion and emissions. The focus is on explaining engine performance in terms of power, energy utilization and exhaust emissions, its relation to internal processes like combustion and gas exchange and varying engine operating conditions. The unit is based on explaining processes and performance by application of first principles in thermodynamics, chemistry, heat transfer, fluid flow and mechanical dynamics. This approach provides a basis for analysing and understanding the complex interactions between subsystems and processes inside the engine system.

Learning Target Outcomes: Upon successful completion of this course, the learner can: 1. Analyse the terms regarding the construction of engines like TDC, BDC, clearance volume, compression ratio & mean effective pressure. 2. Analyze and understand parameters like mean effective pressure & use them to compare the performances of engines of equal size. 3. Examine a broad spectrum of terms used to measure the engines performance and efficiency. 4. Differentiate and draw the P-V diagrams for engine cycles like Otto, Diesel, and Dual combustion cycles. 5. Determine the thermal efficiency, amount of heat transfer, mean effective pressure, highest temperature & pressure in the engine cycles. 6. Examine and extend their knowledge of fuels and engines to different situations of engineering context and professional practice.
