In air standard Diesel cycle, at fixed compression ratio and value of adiabatic index
1
thermal efficiency increases with increase in heat addition cut off ratio
2
thermal efficiency decreases with increase in heat addition cut off ratio
3
thermal efficiency remains same with increase in heat addition cut off ratio
4
thermal efficiency may increase or decrease with increase in heat addition cut off ratio
5
thermal efficiency decreases with increase in Compression ratio
