An Sl engine with a compression ratio rc = 10.1:1 operates on the air standard Otto cycle at 4500 RPM. Maximum temperature in the cycle is 2700 °K and maximum pressure is 8200 kPa. The pressure in the cylinder when the exhaust valve opens is 600 KPa and the exhaust pressure is 98 kPa. The exhaust valve effectively opens at 56° ÞBDC. Calculate: 1. Time of exhaust blowdown in sec 2. The average temperature of the exhaust during the exhaust stroke in °K 3. The maximum flow velocity through the exhaust valve at the start of the blowdown process assuming chocked flow conditions in (m/sec)
