Title: Xu Han: Innovator in Combustion Technology
Introduction
Xu Han is a notable inventor based in Columbus, IN (US), recognized for his contributions to combustion technology. He holds a total of 4 patents, showcasing his innovative approach to improving internal combustion engines.
Latest Patents
His latest patents include "Spark plug configurations with electrode to direct charge flow for a combustion pre-chamber of an internal combustion engine." This invention features electrode arrangements designed to enhance charge flow into and out of the annular volume around the insulator nose and the pre-chamber volume of a pre-chamber device. This design effectively directs the purge of exhaust gases trapped in the annular volume to a space formed by the exterior of the spark plug body and the interior of the pre-chamber device. Another significant patent is "Combustion pre-chamber assemblies for an internal combustion engine." This assembly includes a pre-chamber device body that defines an annular plenum, which is in fluid communication with at least one bore extending through the spark plug shell. The annular plenum also connects to at least one purging passage that extends from the annular plenum to an end surface of the pre-chamber device body. This innovation allows residual exhaust gases in the annular volume of the spark plug to be purged by fresh charge flow from the main combustion chamber as the piston approaches top dead center.
