The improvement of the energy conversion theory of all energy conversion engines has been tried instead of the traditional. As some points for the improvement, there are the distinction of the phenomena between in a combustion chamber [CC] and in a whole engine [WE], the adoption of the total energy supplied instead of heat supplied, the adoption of the energy quantity basing the lowest state of a cycle and so on. As a result, some outcomes of the improvement have been able to be gotten. The theoretical efficiency in a combustion chamber is named in "the theoretical energy conversion efficiency in a CC (η_<EN>= [W_<th>/E_<SU>]_<CC>)". It in a whole engine is named in "the provisional-net energy conversion efficiency in a WE (η_<PN>= [W_<PN>/E_<SU>]_<WE>)" and the efficiency considering losses is named in "the estimated net (brake) thermal efficiency (η_<e(ES)>= [W_<e<ES>>/E_<SU>]_<WE>)". As a result of analyzing of the Sabathe-type engine, the relation between the estimated and the brake has been excellently shown and the target in the future has been demonstrated.
