If an ideal air-standard Otto cycle and an ideal air-standard Diesel cycle operate on the same compression ratio, then the relation between the thermal efficiencies (ηth) of the cycles is
- A. 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜= 𝜂𝑡ℎ,𝐷𝑖𝑒𝑠𝑒𝑙 and 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜< 1
- B. 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜> 𝜂𝑡ℎ,𝐷𝑖𝑒𝑠𝑒𝑙
- C. 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜< 𝜂𝑡ℎ,𝐷𝑖𝑒𝑠𝑒𝑙
- D. 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜= 𝜂𝑡ℎ,𝐷𝑖𝑒𝑠𝑒𝑙= 1
Answer: B. 𝜂𝑡ℎ,𝑂𝑡𝑡𝑜> 𝜂𝑡ℎ,𝐷𝑖𝑒𝑠𝑒𝑙
