柴油发动机是各种空气污染废气的主要来源，例如颗粒物 (PM)、一氧化碳 (CO)、氮氧化物 (NOx)、硫和其他有害化合物。事实证明，通过将含氧化合物混合到基础柴油中可以显着减少这些空气污染物的形成。乙醇混合柴油（e-diesel）是一种比普通柴油更清洁的燃烧替代品，适用于公共汽车、卡车、越野设备和乘用车中使用的重型（HD）和轻型（LD）压燃式（CI）发动机。尽管乙醇已被用作燃料含氧化合物以减少汽油尾气排放，但由于技术限制（即混合），其在柴油中的使用还不可能。由于 Pure Energy Corporation (PEC) 发明的添加剂系统 Puranol 的开发，商业上可行的电子柴油现已成为可能。 Puranol 首次实现了乙醇与柴油在透明溶液中的飞溅混合。实验室和现场测试表明，HD 柴油发动机可减少 41% 以上的颗粒物、27% 的二氧化碳和 5% 的氮氧化物。较小的 1.9 升大众 TDI 发动机可显着提高排放量。
Diesel engines are major contributors of various types of air polluting exhaust gasses such as Particulate Matter (PM), Carbon monoxide (CO), Oxides of Nitrogen (NOx), Sulfur, and other harmful compounds. It has been shown that formation of these air pollutants can be significantly reduced by blending oxygenates into the base diesel. Ethanol blended diesel (e-diesel) is a cleaner burning alternative to regular diesel for both heavy-duty (HD) and light-duty (LD) compression ignition (CI) engines used in buses, trucks, off-road equipment, and passenger cars. Although ethanol has been used as a fuel oxygenate to reduce tail-pipe emissions in gasoline, its use in diesel has not been possible due to technical limitations (i.e., blending). Commercially viable E-Diesel is now possible due to the development of an additive system, Puranol, invented by Pure Energy Corporation (PEC). Puranol allows the splash blending of ethanol in diesel in a clear solution possible for the first time. Laboratory and field tests have demonstrated over 41% reduction in PM, 27% reduction in CO, and 5% reduction in NOx from a HD diesel engine. Significantly higher emissions reductions are observed from smaller 1.9-L VW TDI engines.
