engineering recuitment GATE ME 2023-24 Test Series Internal Combustion Engine IC Engine Cycles Diesel Cycle
In an air standard Diesel cycle, compression ratio is 14. At the beginning of compression of air (R = 287 J/kg.K, Cp = 1005 J/kg.K and γ = 1.4) the temperature is 27°C and the pressure is 1 bar. If the specific volume after heat addition is two times the specific volume after compression then
1
Temperature after the constant pressure expansion process is approximately 1724° C
2
Heat added in the constant pressure expansion process is 866.44 kJ/kg
3
Temperature after the constant pressure expansion process is approximately 1451° C
4
Heat added in the constant pressure expansion process is 489.64 kJ/kg
