The pressure of the 4-stroke engine operating according to the
seilinger cycle at the end of the heat input is 97.45x10 ^ 5 Pa at
the beginning of the heat input 600 ° C. The compression ratio of
the cycle is 17.5 burst (pressure) ratio 1.7, the cutting
(pre-expansion) ratio 1.6 and taking the adiobatic base value of
1.4; What is the temperature at the end of expansion?

The pressure of a motor operating according to the seilinger
cycle is 1.01x10 ^ 5 Pa at the start of compression, the pressure
and temperature at the end of the heat socket are 43,05x10 ^ 5 Pa
and 2410 K, respectively. The temperature at the end of the
expansion is 1150 K. Since the compression ratio of this engine is
11, find the average index pressure by taking the adiabatic base
coefficient of 1.41.
