Problem
1. A four-stroke 2.4-L gasoline engine runs at 2500 RPM and has an efficiency of 60%. The state before compression is 40 kPa, 280 K and after combustion it is at 2400 K. Find the highest T and P in the cycle, the specific heat transfer added, the cycle mean effective pressure and the total power produced.
2. Suppose we reconsider the previous problem and, instead of the standard ideal cycle, we assume the expansion is a polytropic process with n = 1.5. What are the exhaust temperature and the expansion specific work?
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
