Air Standard Cycle	Actual Cycle
Pure air is used.	Working fluid is a combination of air fuel and residual gas in the cylinder.
Composition of working fluid remains constant.	Composition of working fluid changes at every instant of time.
Specific heat of working fluid is considered as constant.	Specific heat of working fluid changes at every instant during combustion
Constant $C_p$ and $C_v$.	$C_p$ and $C_v $ changes.
It consists of reversible processes.	It consists of irreversible processes.
Ideal gas equation ie, PV=mRT is valid  in each point.	Not valid in actual cycles.
No loss of work.	Loss of work due to friction and leakage.
Losses are not considered.	Time loss factor,heat loss factor,exhaust  blow down,piping loss all are considered.
