A 4-stroke 3 litre V6 spark ignition petrol engine has a maximum power output of 100kW at 5500rev/min, and a maximum torque of 236Nm at 3000rev/min. The minimum sfc is 0.090 kg/MJ at 3000 rpm, and the air flow rate is 0.068m²/s. The compression ratio is 8.9:1 and the mechanical efficiency is 90%. The engine was tested under ambient conditions of 20°C and 1 bar. Take the calorific value of fuel to be 44MJ/kg. (a) Determine the power output at...
output input 2. The gearbox in the diagram for problem 1 receives an input power of 10 kW, at a speed of 40. The gears are spur gears (ignore the helix angle on the teeth in the figure), have a module of 5 mm/tooth, and the pressure angle is 20. Assume all shafts lie in the same plane. Assume the gearbox is reasonably efficient, so losses can be neglected for this analysis. (a) Determine the minimum inside dimension of the...

Measurements in the 1800s showed that a draft horse could provide a maximum steady output power over the course of a working day; that's how the "horsepower," about 750 W, came to be defined. Another animal that's used for pulling loads for which there are good data is the sled dog. A 38 kg dog can provide power to pull a sled with a force of 60 N at a steady 2.2 m/s. Dogs and horses have approximately the same...
