A four-cylinder, four-stroke internal combustion engine operates at 2800 RPM. The processes within each cylinder are modeled as an air-standard Otto cycle with a pressure of 14.7 lbf/in2, a temperature of 80°F, and a volume of 0.03 ft3 at the beginning of compression. The compression ratio is 11, and maximum pressure in the cycle is 1080 lbf/in2. Use a cold air-standard analysis with k = 1.4. Determine the power developed by the engine, in horsepower, and the mean effective pressure in lbf/in^2.

IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.
