To investigate the effect of low-molecule-weight gelators on the overall performance of gel fuels， five acylhydrazone-based low-molecular-weight gelators were designed and synthesized. Kerosene gel fuels were prepared using the heating-cooling method， and the gelation mechanism was examined. A comprehensive evaluation system for gelator performance was established based on six parameters： the minimum addition amount of gelators （A）， the phase transition temperature （T_g）， the physicochemical stability （S_pc）， the loss rate of energy density （E_loss）， the shear thinning capacity （S_thin） and the resetting property （R）. The results showed that all gelators could form three-dimensional network structures through non-covalent interactions such as hydrogen bonds and π-π conjugation， effectively confining kerosene molecules. Their gel fuels exhibited thermal reversibility （T_g = 50-80 ℃） and had good physical and chemical stability and shear thinning behavior. Among them， L18 gelator had the lowest minimum addition amount （3.1%） and the fastest gelation speed （15 s）. L5 gelator had the best physical and chemical stability and the mass retention rate was 97.5% at a high centrifugal speed of 10000 r·min^-1. L16 gelator had the strongest shear thinning ability， with a viscosity of only 34.72 mPa·s after shearing. The conclusion indicated that based on the multi-dimensional performance evaluation system established by the institute， L16 and L18 gelators demonstrated significant comprehensive advantages.
