Title: **Lester P. Berriman: A Trailblazer in Emission Control Technology**
Introduction
Lester P. Berriman, an innovative inventor hailing from Irvine, California, has made significant strides in emission control technology, securing a total of 14 patents throughout his career. His inventions have focused on reducing harmful nitrogen oxides in automotive exhaust systems, showcasing his dedication to both engineering and environmental preservation.
Latest Patents
Among his latest contributions to the field are two notable patents. The first is for a system titled **Ammonia storage and injection in NOx control**, which describes a method for storing ammonia as a liquid mixture of ammonia and water. This innovative system efficiently injects ammonia into an engine's exhaust gas stream to reduce nitrogen oxides, enhancing the performance and environmental compliance of engines. The mixture is heated as it passes through a tube in contact with the exhaust gas pipe, effectively separating the ammonia from the water before activation at a nozzle for injection.
The second patent is the **Diverter for catalytic converter**, designed to improve the flow of exhaust gases from a small diameter exhaust gas pipe into a larger catalytic converter assembly. This low-cost solution employs a diverter element with conical walls to ensure even distribution of exhaust gases, effectively directing them toward the periphery of the catalytic converter while maintaining the catalyst's efficiency.
Career Highlights
Lester's impressive career includes stints at Dresser Industries, Inc. and Kleenair Systems, Inc., where he applied his engineering expertise to develop groundbreaking technologies that have a lasting impact on emission control. His contributions to the field of automotive engineering are recognized through his numerous patents and applied inventions.
