A four-cylinder, two-stroke 2.4-L diesel engine that operates on an ideal Diesel cycle has a compression ratio of 22 and a cutoff ratio of 1.8. Use nitrogen as the working fluid which is at 70°C and 97 kPa at the beginning of the compression process. Determine how much power the engine will deliver at 4500 rpm. The properties of nitrogen at room temperature are cp = 1.039 kJ/kg-K, cy= 0.743 kJ/kg-K, R = 0.2968 kJ/kg-K, and k=1.4. The power the engine will deliver is 121.545 kW.

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.
