Diesel technology, once the soot-producing demon of the American mind, is getting cleaner, and Bosch is leading the way with advances in fuel delivery and exhaust treatment. Bosch continues to make advances in diesel technology, and the upcoming Euro 5 regulations (2010) will push them even farther. Particulate emissions are the biggest problem with diesels, and particulate filters will soon make their way into new diesel vehicles. This is nothing really new. Bosch is also developing a new injector technology, which will allow finer fuel control. What is significant in our eyes is talk of using a exhaust treatment for NOx in a diesel engine. Such a system would use a reactant to break NOx fumes into nitrogen and water. As the US begins tightening emission regulations for diesel engines, you can bet some of these technologies will find their way over the pond.
