A four-cylinder, four-stroke spark-ignition internal combustion engine is operating at 2800 rpm. The processes in each cylinder are modeled as an Otto Cycle with a pressure of 14.7 psia, a temperature of 80°F, and bottom dead center volume of 34 in^3 at the beginning of compression. The compression ratio in the engine is 10 and the maximum pressure in the cycle is 990 psia. Determine the following, (a) the power developed by the engine (hp) (b) the thermal efficiency of the engine (c) the mean effective pressure (psia) of the engine.
