| Abstract:The effect of energy density and wall temperature and their interaction on the knock intensity of isooctane/air and n-heptane/air mixtures was investigated on a rapid compression machine. Results show that with the increase of energy density and wall temperature, the knock intensity of both fuels increases significantly. For isooctane/air mixture, the effect of energy density on knock intensity is significantly enhanced with the increase of wall temperature. Moreover, the influence of wall temperature on knock intensity is also significantly enhanced with the increase of energy density. However, the n-heptane/air mixture basically does not have the above relationship, and its knock intensity is always at a higher level, which indicates that the energy density and wall temperature have different influence on the knock intensity for different active fuels. |
