Question
QUESTION 1 An Automotive Engineering company has à task to setup a diesel engine for a new vehicle model. The engine has four-cylinder, four-stroke and 3 liters of displacement volume that operates on the ideal diesel cycle with a compression ratio of 17 as shown in Figure 1. The engine uses light diesel fuel with a heating value of 42,500 kJ/kg and an air-fuel ratio of 24. You are the engineer in the company is given the following task to analyze the engine characteristics based on constant specific heats at 500 K, a) Evaluate all the working temperatures and pressures al all points on P – V diagram. b) Evaluate the thermal efficiency of the cycle. c) If the engine is plan to operate at 3000 rpm, evaluate the power rating produce by the engine.
