Question Design a 4 cylinder inline, turbo diesel engine to produce 103 kW of brake power at design speed when installed in a Multi-Purpose Vehicle (MPV). The square engine operates on a four stroke cycle and produces 20 bar of maximum brake mean effective pressure (bmep). Average piston speed is 11.5 m/s and bmep at peak power is 14.4 bar. If the decided values of torque position and torque increase are 50% and 28% respectively, determine the: a) bore b) stroke c) displacement d) maximum torque e) engine speed at peak torque as well as f) engine speed at peak power

QUESTION 4 A single-cylinder, 4-stroke, 3-liter gasoline engine operates at 800 rpm and a compression ratio of 9. The pressure and temperature at the intake are 103 kPa and 30 °C respectively. The fuel used has a heating value of 42,500 kJ/kg, the air-fuel ratio is 14, and 82 % mechanical efficiency. The length of the indicator card is 60mm with an area of 520 mm² and the spring scale is 0.85 bar/mm, considering a volumetric efficiency of 95%, 25% excess air, and k = 1.37. Determine the Brake Engine Efficiency in (%). Note: Use four (4) decimal places.
