Title: Innovations by Mark R Chapman
Introduction
Mark R Chapman is an accomplished inventor based in Brighton, MI (US). He has made significant contributions to the field of exhaust systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and effectiveness of particulate filters in automotive applications.
Latest Patents
One of his latest patents is the "Electrically heated particulate filter embedded heater design." This innovative exhaust system processes emissions generated by an engine. It features a particulate filter (PF) that filters particulates from the exhaust. The upstream end of the PF receives exhaust from the engine, and its upstream surface includes machined grooves. A grid of electrically resistive material is inserted into these grooves, selectively heating the exhaust to initiate combustion of particulates within the PF.
Another notable patent is the "Overlap zoned electrically heated particulate filter." This system includes a particulate matter (PM) filter with an upstream end for receiving exhaust gas and a downstream end. It features a zoned heater arranged spaced from the upstream end, comprising multiple zones and sub-zones. A control module selectively activates specific zones to initiate regeneration in downstream portions of the PM filter.
