New Diesel Technologies

New advanced diesel technologies have made these engines cleaner, quieter and more powerful than ever before. Some of these revolutionary innovations include:  

Diesel Retrofit Technologies

The diesel industry is constantly innovating new solutions to clean up existing diesel engines that run for millions of miles. Employing emissions control systems and devices, owners of diesel products are able to make the most out of their investment in diesel technology. See the image to the right to view a white handkerchief test in action, a demonstration where a white handkerchief remains clean even when held in front of an exhaust pipe.

High Efficiency Diesel Particulate Filters (DPFs)

A high efficiency diesel particulate filter (DPF) removes PM in diesel exhaust by filtering exhaust from the engine. The filter systems can reduce PM emissions by 80 to greater than 90 percent.
