Title: Innovations by Jeffrey Marley in Emissions Monitoring
Introduction
Jeffrey Marley is an accomplished inventor based in Hagerstown, MD (US). He has made significant contributions to the field of emissions monitoring, holding a total of 2 patents. His work focuses on developing advanced technologies to monitor and improve vehicle emissions.
Latest Patents
One of Jeffrey Marley's notable patents is an engine exhaust emissions monitoring device. This device includes a pipe designed to mount to the tailpipe of a vehicle, featuring a cable that connects to the vehicle's engine control unit (ECU) and power system. The pipe has an internal flow passage that allows exhaust to flow through. A variety of sensors are mounted on the pipe, each extending through an access port to be exposed to the internal flow passage. These sensors measure exhaust properties and constituents, with multiple sensors dedicated to each constituent, including NOx, temperature, ammonia, and particulate matter. The data collected by the sensors is communicated to a processor/data logger also mounted on the pipe.
Another significant patent is a method for detecting abnormally frequent diesel particulate filter (DPF) regeneration. This method involves measuring a pressure drop across the DPF and using this measurement to calculate a pressure drop-based soot load estimate. It also includes calculating soot output from an engine model and comparing it with the emissions-based soot load estimate. A warning is provided if the difference between these estimates exceeds a predetermined threshold.
