Lecture with animations and video ( 1, 2 ) shown via projector. Introduction to Otto Cycle, Cycle Thermal Efficiency, Spark-Ignition Engine Architecture, and Combustion Cycle Class 8Īt the completion of the lecture, students should:ġ) Understand the working principle of a real internal combustion engine (ICE) operating via spark-ignition (SI).Ģ) Recognize the approximate P-V cycle of a real SI-ICE engine.ģ) Apply thermodynamic processes to approximate the SI-ICE cycle as the Ideal Otto cycle.Ĥ) Identify the importance of the design parameter “Compression ratio” and apply it to the Otto cycle.ĥ) Be able to calculate the maximum theoretical efficiency of the Ideal Otto Cycle.Ħ) Understand engine design constraints due to ambient conditions, fuel properties, and engine integrity.ħ) Understand using general polytropic processes for the compression and expansion strokes to simulate heat transfer during cold early-startup times and later hot-engine times.
