MWCNT fuel additive

Combined with flash boiling, suppresses soot

Used as a GDI fuel additive, multi-walled carbon nanotubes synergize with flash boiling to improve mixture homogeneity and promote finer, more open, and more oxidizable soot aggregates.

Advantages

Spray width drastically reduced

Under combined flash boiling and MWCNTs, spray width is reduced by 76.47%, promoting fuel concentration and deep penetration.

Faster flame propagation

Flash boiling increases flame radius and speed by 12.68% and 13.9%, respectively, and MWCNTs further accelerate combustion.

Finer, more open soot

Primary soot particle diameter median drops by 46.21% with lower fractal dimension, producing open, branched structures that are more easily oxidized.

Applications

• Clean alternative fuels：Used in GDI engines to reduce soot emissions for cleaner combustion.
• Internal combustion engine combustion optimization：Provides synergistic flash boiling and nanoadditive strategy to accelerate flame and improve mixing.
• CNT functional applications：MWCNTs act as fuel additives with catalytic and heat transfer effects.
• Nanoadditive enhancement：Nanoadditives alter spray properties and suppress soot particle growth.
