BorgWarner develops new turbocharger to help reduce diesel emissions
BorgWarner has developed a new turbocharger design that it claims will help reduce diesel emissions. One of the methods used to reduce emissions of nitrogen oxides from diesel engines is to recirculate some of the exhaust gases (EGR). Low pressure EGR helps to reduce the combustion temperatures and thus the production of NOx. However injecting the exhaust gases upstream of the turbo compressor has caused problems in the past as the exhaust particles and high temperature of the exhaust have caused metal fatigue. Downstream injection requires higher pressures. BorgWarner has developed new materials and coatings that can better withstand low pressure EGR and resist particulate deposits on the compressor wheels. Two European manufacturers are expected to introduce the new turbochargers on their U.S. diesel engines in 2008. Volkswagen, BMW and Mercedes Benz are introducing new clean diesels this year.
