It is difficult to measure the combustion efficiency in the unsteady process of detonation combustion. Therefore, isoctane was used as gasoline single-component alternative fuel and its simplification mechanism was established to numerically simulate the flame acceleration and the DDT process of gaseous gasoline. The gas analysis method was used to study the detonation combustion efficiency under different sampling conditions. The results show that the simplification mechanism model is in good agreement with the combustion characteristics of isooctane within the study range. The numerical study finds that in the detonation combustion process, the concentration of gas components in different regions after detonation wave is quite different and that the combustion near the flame front is not sufficient, thus there being a lot of intermediate products. After detonation wave passes by, the combustion continues. At the same time, the reverse wave may promote the further reaction of combustion and make the combustion more complete. When the equivalent ratio is 1, the average concentration of all gases after detonation wave was taken to calculate the combustion efficiency, which is 82.6%.
