A Diesel Cycle

See the attached file.
The cycle consists of the following stages;
1) 2 air is compressed adiabatically.
2) 3 heat is added at constant pressure.
3) 4 air is expanded adiabatically.
4) 1 air is cooled at constant volume.
An engine operating on a Diesel cycle takes in air at state 1 at 1 bar and 12oC. The maximum cycle temperature is at state 3 and is 1000oC. The ratio of the volume at state 1 to that at state 2, known as the compression ratio is 11. The cycle efficiency is given by;
?_(l )= 1 - ((T_4-T_1 ))/?(T_3-T_2 )
Determine the efficiency of the cycle.
A p-V diagram for a diesel cycle is shown in the attached document.
