Differentiate between Otto Cycle and Dual Cycle.

Describe the four processes involved in the Stirling cycle.

Task 1 A V-8 Spark ignition engine has a 10 cm diameter bore and 10 cm stroke. At the beginning of compression process air is at 95 KPa and 27 Degree Celsius. 750 KJ/Kg of heat was transferred to air during heat addition process. The compression ratio is 8. Consider the variation of specific heats with temperature. A. Describe with the aid of diagrams the operational sequence of four stroke spark ignition engines B. Explain the mechanical efficiency for ideal otto cycle of two and four stroke engines C. What is the difference between four and two stroke spark ignition engines? D. Explain the relationship between thermal efficiency (n) and compression ratio (r). E. Why are high compression ratios not used in spark ignition engines? F. Determine the net-work output per cylinder per cycle (KJ) G. Determine the efficiency of the engine. H. Determine the Mean Effective Pressure (kPa) I. What is the Power Output of the engine running at 2000 rpm. Task 2 A compression ignition engine operates…
