The Lubrizol Corporation and Caterpillar have announced that they are developing a low-emission diesel fuel. The new fuel will be sold under the name PuriNOx Performance Systems.

PuriNOx fuel is a stable blend of additives, water and diesel fuel. Tests indicate that, when compared to commercial diesel fuel, PuriNOx fuel significantly reduces two critical emissions – NOx and particulates. PuriNOx reduces NOx emissions by 5-30 per cent, and particulate emissions by 20-50 per cent. The fuel can be used in old and new diesel engines, and requires no modification to fuel systems or engine hardware.

PuriNOx Performance Systems’ products are under laboratory and market evaluation. PuriNOx Performance Systems will be offered commercially in emission-sensitive regional areas, such as California.
