A diesel cycle operates with a compression ratio of 16:1. The conditions at the beginning of compression are T= 90 F , p= 14.6 psia. The maximum volume in the cylinder is 85 in^3. The maximum temperature in the cycle is 1740 degrees R. The cycle can be considered ideal, except, that the compression stroke is only polytropic with n = 1.31.

A) what is the mass of (air + fuel) in the cylinder?
B) what is the maximum pressure in the cycle?
C) what is the cutoff ratio for the cycle?
D) calculate the equivalent heat transport into the cycle for the combustion process.
E) what is the exhaust temp for the cycle?
F) calculate the net work transport for the cycle.
G) what is the cycle efficiency for the cycle? Compare it to the Carnot efficiency for these temperature limits.

Please help asap and please show all work. Thanks!
