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?

Answer #1

The pressure at the end of the ist input of a 4-stroke engine
operating according to the Selinger Cycle is 97.45x10 Pa, and the
temperature at the start of the heat input is 600 ° C. The
compression ratio of the cycle is 17.5 and the blast (pressure)
ratio is 1.7. Which of the following is the temperature at the end
of the expansion by taking the cut (ten expansion) ratio 1.6 and
the adiabatic ús value 1.4?

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.
