**1.**Show that the efficiency of an ideal diesel engine is given by

An 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 20^{o}C.If the maximum temperature in the cycle is not to exceed 2200 K,

Determine:

a) the thermal efficiency

b) 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.
