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...

2. Analyze an Audi 3.0-liter TDI V6 Biturbo diesel engine using an air-standard Diesel cycle that addresses the "real" effects of non-isentropic compression/expansion, air-fuel ratio, fuel heating value, incomplete combustion, exhaust residual, and heat loss. The engine is four-stroke, has six cylinders with a compression ratio of 16.0, and develops maximum power at 4250 rpm. Assume the following: the diesel fuel heating value is Quv 42,600 kJ/kg, the air-to-fuel ratio (AF) at maximum power is 25, and the combustion efficiency...
