OTTO CYCLE At the start of an air-standard Otto cycle's compression process, P1 = 1 bar, T1 = 300 K, V1 = 380 cm3. The maximum temperature in the cycle is 2400 K and the compression ratio is 9. Determine the: (a) heat addition, in kJ (b) the net-work in kJ (c) the thermal efficiency (d) the mean effective pressure, in bar. Show complete solution.

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.
