Lubrizol and Caterpillar Codeveloping Low-Emission Diesel Fuel

The Lubrizol Corporation and Caterpillar Inc. are developing a low-emission diesel fuel designed for use in commercial service diesel engines. This unique fuel technology utilizes Lubrizol's performance chemistry and system capabilities and Caterpillar's diesel engine combustion and emissions knowledge. The new fuel will be sold by fuel marketers and distributors and supported by fully integrated chemical, electronic and mechanical components sold by Lubrizol under the name PuriNOx Performance Systems. PuriNOx fuel is a stable blend of additives, water and commercial diesel fuel. Tests indicate, when compared to commercial diesel fuel, PuriNOx fuel significantly reduces two of the most critical emissions from compression ignition diesel engines - nitrogen oxides (NOx) and particulates. PuriNOx fuel reduces NOx emissions by five to 30 percent and particulate emissions by 20 to 50 percent. The fuel can be used in older and newer diesel engines and requires no modification to fuel systems or engine hardware. PuriNOx fuel will be blended utilizing Lubrizol's proprietary PuriNOx blending units to meet the needs of fuel marketers and distributors, and fuel users.
