Title: Stewart D. Sullivan: Innovator in Engine Technology
Introduction
Stewart D. Sullivan is a notable inventor based in Columbus, IN (US). He has made significant contributions to the field of engine technology, holding 2 patents that enhance the performance and efficiency of internal combustion engines.
Latest Patents
One of his latest patents is the "Mass air flow sensor signal compensation system." This invention provides a method and system for compensating a mass air flow signal produced by a mass air flow sensor in fluid communication with an air intake passageway of an internal combustion engine. The system monitors the mass air flow signal and determines the expected oxygen concentration of exhaust gas produced by the engine. A compensation parameter is calculated based on the expected and measured oxygen concentrations, leading to a compensated mass air flow value.
Another significant patent is the "System for controlling regeneration of exhaust gas aftertreatment components." This system and method control the regeneration of exhaust gas aftertreatment components coupled to an internal combustion engine. It monitors the particulate load of a particulate filter and the road speed of the vehicle. If the particulate load exceeds a certain threshold while the road speed is adequate, regeneration of the particulate filter is initiated. Additionally, it monitors the sulfur oxide load of a NOx catalyst, ensuring efficient management of exhaust gas treatment.
