 Fuel Emulsion- Micro Explosion 

  • A water-in-fuel emulsion is a specialized mixture wherein reclaimed and filtered water, including greywater, rainwater, and other sources, are blended into fuels using an organic emulsifier. This emulsification process creates a homogeneous mixture wherein water droplets are dispersed within the fuel matrix.

  • Micro-explosion refers to a phenomenon occurring during combustion, wherein suspended emulsion particles within the fuel reach their superheated stage more rapidly than the surrounding fuel. This rapid heating causes the emulsion particles to undergo expansion and breakup, resulting in the formation of extremely fine combustion particles.

  • SJU's patent-pending process encompasses precise control over various parameters, including the emulsion composition, size of dispersed emulsion particles, and droplet size. Through an in-line system, the process maintains optimal pressure and temperature conditions to ensure the desired combustion dynamics, consequently leading to reduced fuel consumption and emissions.

  • This effect is achieved through the implementation of SJU's innovative chemical and mechanical processes, safeguarded by patents, which meticulously regulate the combustion environment to maximize efficiency and environmental performance.

 Break Thermal Efficiency (BTE) 

•Brake Thermal Efficiency improves due to an ignition delay when the emulsion expands and vaporizes causing the micro-explosion.

•Ignition delay leads to a higher heat release rate, higher fuel burning in the pre-mixed stage and better BTE.


•Increase in flame propagation speed and flame-lift-off length with emulsion fuel, promotes better mixing of air-fuel mixture and results in complete combustion.

 Mechanical Homogenizer 

SJU 111_edited_edited_edited.jpg

 SJU Process 

  1.   Marginal energy use

  2.   Process done before or after fuel delivery

  3.   No separation of elements

  4.   Chemical blending produces an homogenized mixture

  5.   Water expansion produces micro explosion, thus complete atomization

  6.   Complete atomization yields fuel  efficiency in the double digits, reducing SOx, COx, NOx and Particulate Matter (PM)

SJU 106_edited_edited.jpg
  1.   High energy use equipment to blend elements

  2.   Process done right before combustion

  3.   Immediate separation of elements

  4.   Lack of chemical blending, thus no homogenized mixture

  5.   Micro explosion produces inconsistent atomization

  6.   Water in the combustion chamber helps reduce NOx

  7.   No fuel efficiency nor reduction of COx and Particulate Matter (PM)
