Water-diesel emulsion could cut diesel emissions by 60%

A potential game-changer in the fight against diesel pollution has emerged in the form of a water-based fuel additive that slashes emissions by 60% without requiring engine modifications.

Researchers discover water-diesel emulsion to reduce diesel emissions

Scientists at the Federal University of Technology Owerri have developed a technology called Water-in-Diesel Emulsion (WiDE) that introduces tiny water droplets into diesel fuel using surfactants, creating a stable mixture that can last for weeks.

During combustion, these minute water droplets transform into vapor, generating small explosions inside the engine that break down the fuel into much finer particles. This process, known as micro-explosion, improves the mixing of diesel and oxygen within the combustion chamber, resulting in a more homogeneous and efficient burn that reduces unburned pollutants.

Data from various studies highlight the potential of WiDE, demonstrating reductions of up to 67% in nitrogen oxides and 68% in particulate matter compared to conventional diesel.

The vaporization of WiDE's water also reduces peak combustion temperatures, minimizing the formation of nitrogen oxides, while improved fuel oxidation helps reduce particulate emissions.

Beyond cleaner air, initial tests suggest WiDE could also boost engine thermal efficiency, allowing some motors to consume less fuel for the same power output. While diesel vehicles took a beating, now a study by experts claims gas engines aren't far behind.

Researchers describe WiDE as a practical and cost-effective way to make engines cleaner, saying it offers an immediate path to lower emissions without requiring engine redesigns.
