An engine operates on the air-standard diesel cycle. The condition at the start of compression are 27 degree celsius and 100kPa. The heat supplied is 1840kJ/kg, and the compression ratio is 16. Determine the maximum temperature and pressure, the thermal efficiency and the mean effective pressure.

1. An engine operates on the air-standard diesel cycle. The condition at the start of compression are 27 degree celsius and 100kPa. The heat supplied is 1840kJ/kg, and the compression ratio is 16. Determine the maximum temperature and pressure, the thermal efficiency and the mean effective pressure.

2. Calculate the bore and stroke of a six-cylinder engine that delivers 22.4 kW at 1800 rpm with a ratio of bore to stroke of 0.71. Assume the mean effective pressure in the cylinder is 620 kPa and the mechanical efficiency is 85%.

3. A spark-ignition engine produce 224 kW whle using 0.0169 kg/s of fuel. The fuel has a higher heating value of 44 186 kJ/kg, and the engine has a compression ratio of 8. The friction power is found to be 22.4 kW. Determine the brake thermal efficiency, mechanical efficiency,and the rest of the efficiencies.
