Compression ratio 'r' and Efficiency 'η' of Otto and Diesel cycles - GATE ME '00

Consider air standard Otto and Diesel cycles, both having the same state of the air at the start of compression. If the maximum pressure in both the cycles is the same, the compression ratio 'r' and the efficiency 'η' are related by ___

A. r(Diesel) > r(Otto)

B. r(Diesel) < r(Otto)

C. η(Otto) > η(Diesel)

D. η(Otto) < η(Diesel)

Answer:

Compression ratio 'r' and Efficiency 'η' of Otto and Diesel cycles

efficiency of otto vs diesel cycles for same maximum pressure in cycle
