Catalysts for Diesel Engines
Governments around the world have adopted tighter emission standards related to nitrogen oxide and particulate matter from diesel-powered vehicles and various regulatory programs have been put in place to address the millions of diesel engines already in use.
According to the U.S. Environmental Protection Agency (EPA), reducing emissions from diesel engines is one of the most important air quality challenges facing the country today. The EPA established the National Clean Diesel Campaign (NCDC) to promote diesel emission reduction strategies. The NCDC includes regulatory programs to address new diesel engines as well as innovative programs to address the millions of diesel engines already in use. Diesel engines power the movement of goods across the nation, help construct buildings, help build roads, and carry millions of children to school each day. While diesel engines provide mobility and are critical to the nation’s economy, exhaust from diesel engines contains pollutants that negatively impact human health and the environment. Diesel engines emit large amounts of nitrogen oxide, particulate matter and air toxics, which contribute to serious public health problems. The EPA estimates that more than 20 million diesel engines in operation today do not meet the new clean diesel standards, yet the engines can continue to operate for 20 to 30 years.
Current techniques for diesel engines to meet emissions standards require the use of several methods, including diesel oxidation catalysts, catalyzed diesel particulate filters, and selective catalytic reduction systems.
Our Solution
We have been producing diesel oxidation catalysts since 2000. In addition, we are working with leading heavy duty diesel engine and substrate manufacturers to develop diesel oxidation catalysts, catalyzed diesel particulate filters and selective catalytic reduction systems utilizing our MPC® technology to meet U.S. and European light and heavy duty regulations with minimal or no platinum group metals. We offer a full range of catalyst products for the control of carbon monoxide, hydrocarbons, particulate matter and nitrogen oxides in light and heavy duty applications.
