Mechanical Engineering
In a diesel engine, the compression starts at 11 pounds per square inch absolute (psia) and 111 degrees Fahrenheit. The compression ratio, denoted by rk, is 14.1, and fuel cut-off happens at 6% of the stroke. The engine is considered light-loaded, and the compression process follows a cold-air standard. You are asked to determine the state points in all corners of the cycle for a unit mass, find the mean effective pressure, and compute the air-standard efficiency.
