QUESTION I Figure I shows cylinder block and piston of a reciprocating engine run with diesel fuel. The engine has displacement volume of 3000 cm and has clearance volume. Consider that the engine is a four-cylinder and four-stroke operates on the Diesel cycle with a compression ratio of 18 and cutoff ratio of 2. The pressure and temperature of air is at the beginning of the compression process is dependent on local ambient condition. Using constant specific heats at 500 K: i) decide working condition at the beginning of the compression process and calculate all the working temperature and pressure at all points on P-V diagram for the engine, ii) determine the net work output and the thermal efficiency, ii) determine the mean effective pressure, iv) develop expression of Power (P) as a function of rotational speed (N), and v) plot graph of Power versus Engine speed (RPM) for the above engine from 0 - 4500 rpm. Please provide complete table of Power versus Engine speed. What is the power rating that can be produced by the cycle if the speed is 3000 rpm.
