    As Carnot engine is an ideal engine(which is not practically possible, since no process is ideally reversible). it is a cyclic process and for reversible cyclic process, entropy change is zero in complete cycle. Hence you can set no heat loss. But any other engine(not Carnot, i.e. not reversible) will always loose some heat. hence we can say, any among all engines working between same temperatures, Carnot is the most efficient. Do ask doubts if any. Best regards.
