Q3: You are designing a four-stroke cycle diesel engine to provide a brake power of 300 kW naturally aspirated at its maximum rated speed. Based on typical values for bmep and maximum mean piston speed, estimate the required engine displacement, bore and stroke for sensible cylinder geometry, also find the number of engine cylinders. What is the maximum rated engine speed (rev/min) for your design? What would be the brake torque (N-m) and the fuel flow rate (g/hr) at this maximum speed? Assume a maximum mean piston speed of 12 m/s is typical of good engine designs.
