Chevron Introduces Low-Emission Diesel Fuel
Chevron Products Co. announced the launch of a lower-emissions fuel for diesel engines. Proformix, a new cost-effective, cleaner-burning fuel, significantly reduces particulate matter (PM) and oxides of nitrogen (NOx). Chevron is introducing the new fuel in limited quantities to on- and off-highway commercial customers in Southern California. “Proformix fuel instantly reduces emissions from most existing diesel engines without hardware add-ons, engine modifications or replacements required by many other diesel fuel alternatives,” said Sheila Taylor, vice president of U.S. Marketing, Chevron Products Co. “It is a ‘fill-and-go,’ solution for our commercial customers to reduce emissions.” Chevron is using this technology through an agreement with The Lubrizol Corporation, a fluid technology company specializing in high-performance chemicals, systems and services. Proformix is a “water-in-fuel” diesel blend that is created using a high-speed blending process that produces water droplets under one micron in size. These droplets are encapsulated by additives that prevent them from coalescing, making them invisible to the engine while improving combustion to reduce emissions. The California Air Resources Board (ARB) verified the emission benefits of the technology with data showing PM reduction of 63 percent and NOx reduction of 14 percent. The fuel is initially available to commercial accounts at Chevron's Montebello, Calif., terminal. The product is marketed to on- and off-highway commercial customers with centrally fueled fleets or equipment, including buses, waste management fleets, agricultural/construction equipment and stationary power generators.
