Question:-
In an air-standard Diesel cycle, r is the compression ratio, r is the fuel cut-off ratio and l is the adiabatic index (Cp/Cv). Its air standard efficiency is given by
Option (A)
Option (B)
Option(C)
Option(D)
Correct Option:
(C)
Question Solution:
hdiesel = 1 – (1/rg-1) [(rg-1) / g(r-1)]
h of diesel engine increases as the load on the engine decreases and at limiting condition become equal to otto. With increases in load cut off increases.
