Researchers in Nigeria found a way to reduce pollution from diesel engines by over 60% without hurting their performance. They mixed small amounts of water with diesel fuel, which lowered harmful emissions and improved engine efficiency.

Diesel engines are used in many places, like transportation and industry, because they're reliable and strong. However, they also produce a lot of air pollution. Diesel exhaust contains nitrogen oxides and particulate matter, which can cause smog, respiratory problems, and climate issues.

A team at the Federal University of Technology Owerri in Nigeria looked for ways to reduce these emissions without hurting engine performance. They found that adding small amounts of water to diesel fuel could lower harmful emissions by over 60% while keeping engines efficient.

This technology, called Water-in-Diesel Emulsion (WiDE), mixes tiny droplets of water with diesel fuel using special chemicals called surfactants. The water turns into vapor quickly when the fuel burns inside the engine, which helps break up the fuel and improve combustion. This leads to lower peak temperatures, reducing nitrogen oxide formation, and more complete burning of fuel, decreasing particulate emissions.

Studies showed that engines running on WiDE reduced nitrogen oxide emissions by as much as 67% and particulate matter emissions by up to 68% compared to standard diesel fuel. Additionally, some experiments found improvements in brake thermal efficiency, which means the engines used fuel more efficiently.

The researchers believe that WiDE could be a simpler and cleaner option for reducing pollution from existing diesel engines without requiring modifications. They also think it could work alongside other clean technologies to support broader climate and air quality goals.

Why It Matters

This technology can help reduce air pollution in India, which is a major problem in many cities. By using WiDE, we can make our environment cleaner and healthier for future generations.
