Explanation:
The Otto cycle is a constant volume cycle used in spark-ignition internal combustion engines. The cycle consists of four processes: intake, compression, power, and exhaust.
The maximum specific output of the Otto cycle can be achieved by following certain conditions:
1. Working Fluid:
The working fluid should be air. This is because air has a high specific heat ratio and can undergo large temperature changes without phase change. This leads to a higher thermal efficiency of the cycle.
2. Speed:
The speed of the engine should be high. This is because a higher speed allows for more cycles per unit time, which results in more power output.
3. Suction temperature:
The suction temperature should be high. This is because a higher suction temperature leads to a higher compression ratio, which results in a higher thermal efficiency of the cycle.
4. Temperature of working fluid at the end of compression and expansion:
The temperature of the working fluid at the end of compression and expansion should be equal. This is because the cycle is a constant volume cycle, and any temperature difference between the two points will result in a decrease in the thermal efficiency of the cycle.
Hence, option D - temperature of the working fluid at the end of compression and expansion should be equal - is the correct answer.
