A four cylinder two stroke Diesel engine has a cut-off ratio of 1.8 and a compression ratio of 22. It operates with an idealized Diesel cycle. At the beginning of the compression stroke, the air in the engine is at 97 kPa pressure and a temperature of 70°C. If the cold-air assumptions can be applied, determine how much power the engine produces when running at 2300 rpm.
