Owerri Researchers Cut Diesel Emissions by Up to 68% With Water-in-Diesel Fuel
1 articles · Updated · ScienceDaily · Jul 1
Summary
A review led by Federal University of Technology Owerri found water-in-diesel emulsion can cut nitrogen oxides by as much as 67% and particulate matter by up to 68%, while sometimes improving engine efficiency.
Tiny water droplets dispersed with surfactants stay stable for up to 60 days; inside the engine they trigger “micro-explosions” that improve fuel-air mixing and lower combustion temperatures.
That combination reduces soot through more complete combustion and suppresses NOx by cooling peak burn temperatures, offering a cleaner option without redesigning diesel engines.
The researchers said surfactant choice is critical to stability and performance, and called for more long-term testing on formulations and engine wear as WiDE is developed alongside biodiesel and exhaust-control systems.
If water slashes diesel pollution by 60%, what's stopping this simple fix from going global?
Is adding water to diesel a genius climate fix or a risky detour from phasing out fossil fuels?
FUTO’s 2026 Review: Water-in-Diesel Emulsion (WiDE) Cuts NOx and PM Emissions by Over 65%
Overview
In July 2026, FUTO researchers released a comprehensive review highlighting the significant potential of Water in Diesel Emulsion (WiDE) fuel technology. The review explains that WiDE is a promising solution for regions that rely on diesel engines, offering a pathway to cleaner and more sustainable energy use. When WiDE combusts, water droplets turn into steam, causing microexplosions that break the fuel into finer particles. This process leads to better mixing of air and fuel, resulting in more complete combustion and significantly reduced harmful emissions. These benefits make WiDE an attractive and practical alternative for cleaner diesel engine operation.
