IC engines

The term "engine" indicates a mechanical device/machine used to convert input energy to a specific mechanical output. The input energy may be in the form of chemical energy, thermal energy, or so on and mechanical output is in the form of mechanical energy (work done). Generally, the engines classify into two groups which are internal combustion type and external combustion type, and further, these two types can be classified into two types that are reciprocating and rotary engines.

Question

of compression are 57°C and 603°C respectively, whilst those at
the beginning and end of expansion are 1950°C and 870°C

0.287 kJ/kg K and y = 1.4, (a) the heat received in kJ, (b) the
heat rejected in kJ, (c) the work done in kJ, and (d) the ideal
thermal efficiency. If the compression ratio is 14:1 and the
pressure at the beginning of compression is 100 kPa, determine
the maximum pressure in the cycle.
