Investigation and Improvement of the Effectiveness of a Gasoline Particle Filter

This research will investigate the effectiveness of a gasoline particulate filter (GPF) and finding ways to improve the existing technology. The GPF is a promising technology that can reduce particulate matter over 99%. Not only this, but when coupled with a three-way catalyst wash coat, otherwise known as a 4-way catalyst, the GPF also significantly decreases NOx, THC, and CO emissions. This research aims to suggest ways of improving the GPF specifically for on-road uses. Much of the previous GPF work has only been done on with chassis dynamometer testing which can produce significantly different emissions compared to on-road driving. By understanding exactly how a GPF works including the pros and cons, more particle filters can be created specifically for different renewable fuels to decrease emissions from all sources.
