Air at 14.7 psia, 40 oF enters an ideal four-stroke Diesel cycle with a compression ratio of 20 and a displacement of 300 in3. It runs at 2100 RPM and the maximum temperature is 3300 oF. The fuel has an energy content of 19,360 Btu/lbm. a. The power output of the engine in Hp b. The cycle thermal efficiency c. The fuel consumption rate in lbm/hr
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...
