    Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...

    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...

    A diesel engine with a compression ratio of 14.5 starts the compression stroke with air at 101 kPa and 42ºC. Fuel with a heating value of 43,260 kJ/kg is used with a fuel/air ratio of 0.03 kg fuel/kg air. At full throttle the airflow to engine is measured to be 0.1 m3/s and 5% of the fuel does not burn due to poor fuel-air mixing. Model the engine as airstandard with variable specific heats, draw the cycle on a P-V...

    A mechanically coupled supercharger is run by a four-stroke four –cylinder square diesel engine with a bore of 100 mm. Air enters the compressor at 27 °C and the compressor pressure ratio is 1.6. From the compressor the air is passed on to a cooler where 1200 kJ/min of heat is rejected. The air leaves the cooler at 67 oC. Some air from the compressor is bled after the cooler to supercharge the engine. The volumetric efficiency is 85 %...
