다국어 초록 (Multilingual Abstract)

This paper is the third of several companion papers which compare the method of Air-Fuel ratio determination in the previous works, Eltinge chart was expanded to arbitrary fuel composition as a reference exhaust composition The compensation of unburned hydrocarbon Ⅲ Eltinge chart and comparison of Spindt and Eltinge method were also discussed in addition to Eltinge and Spindt's one, however, there are many methods which calculate Au-Fuel ratio from exhaust mission Among these methods, carbon balance and oxygen balance are widely used in practice In some applications, linear formula from statistical method is being used in the field due to Its simplicity and convenience In this paper, these various methods are evaluated and compared with Eltinge results and new linear formula is proposed for the gasoline fuel The results show that the corrected carbon balance equation has excellent agreement with Eltinge and Spindt's one On the other hands, the oxygen-balanced formula has a limitation according to the mixture state and AFR For gasoline fuel, newly proposed linear equation has good compatibility with Eltinge and Spindt up to AFR 17.
