7-3-4 [OLO] An engine equipped with a single cylinder having a bore of 12 cm and a stroke of 50 cm operates on an Otto cycle. At the beginning of the compression stroke air is at 100 kPa, 25°C. The maximum temperature in the cycle is 1100°C. (a) If the clearance volume is 1500 cc, determine the air standard efficiency. (b) At 300 rpm, determine the engine output in kW. Use the PG model. (c) What- if Scenario: What would the efficiency and engine output be if the clearance volume were reduced to 1200 cc?
