1.Show
that the efficiency of an ideal diesel engine is given byAn ideal diesel engine has a
compression ratio of 20 and uses air as the working fluid.The state of air at the beginning of the
compression process is 95 kPa and 20oC.If the maximum temperature in the cycle is
not to exceed 2200 K Determine:a)
the thermal efficiencyb)
the mean effective pressure(0.635 9.33.16 kPa)2.How does the
cut-off ratio affect the efficiency of a diesel engine?A four cylinder 3 L diesel engine which operates on
the ideal diesel cycle has a compression ratio at 17 and a cut-off ratio at
2.2.Air is at 300 K 97 kPa at the
beginning of the compression process.Calculate the power delivered by
the engine if it is running at 1500 rpm.
