Benefits of technology
The patent describes a method of improving the efficiency of a diesel engine. This is achieved by removing a diesel particulate filter from the engine and cleaning it with a special cleaning composition containing a fatty acid derivative. The technical effect of this method is to reduce emissions and improve engine efficiency.
Problems solved by technology
Eventually, the build-up of soot and / or ash on the particulate filters reduces the effectiveness of the filter and the efficiency of the engine eventually preventing the engine from operating.
However, even after initiating such regeneration processes, particulate matter may remain on the diesel particulate filters.
In many instances, the particulate filters cannot be cleaned in an effective and efficient manner thereby requiring the diesel particulate filter to be replaced.
However, constant replacement of the particulate filter can be quite costly.

Abstract
The present invention is directed to a method of cleaning a diesel particulate filter. The method requires a step of contacting the diesel particulate filter with a cleaning composition containing one or more fatty acids or a derivative thereof. The one or more fatty acids or a derivative thereof may include a natural oil, such as a plant-based oil.
Description
FEDERAL RESEARCH STATEMENT[0001]This invention was made with Government support under Contract No. DE-AC09-085R22470, awarded by the U.S. Department of Energy. The Government has certain rights in the invention.BACKGROUND OF THE INVENTION[0002]Diesel particulate filters are commonly employed to reduce the particulate matter from the exhaust in many applications that employ diesel engines. These applications can include, but are not limited to, heavy industrial equipment, locomotive equipment, commercial transport vehicles, passenger vehicles, generators, farm equipment, mining equipment, and the like. In general, the purpose of the diesel particulate filters is to collect particles, such as soot and ash, and minimize the amount of such matter that is released into the environment. Commonly, the filters are comprised of a honeycomb-like structure, either made of materials such as stainless steel or ceramics, often with a catalytic coating.[0003]Eventually, the build-up of soot and / or...
