Diesel engines power everything from freight trucks and farm equipment to generators and industrial machinery. They are valued for their strength, durability, and fuel efficiency. But there is a downside. Diesel exhaust is a major source of air pollution, releasing gases and particles that can harm human health and contribute to environmental problems.
Now, researchers in Nigeria say a surprisingly simple solution may help tackle that problem. According to a review of studies from around the world, mixing small amounts of water into diesel fuel could dramatically reduce harmful emissions while preserving, and in some cases even improving, engine performance.
