Abstract

The invention relates to a system and method which are used for improving the sensor performance of vehicle sensors like an exhaust sensor and detecting the predefined substances in fluids which flow through pipes, comprising a structure which extends into the pipes and comprises at least an inlet which is used for receiving the fluids flowing through the pipes and at least an outlet which is basically opposite to at least an inlet; wherein, the structure relocates basically all fluids which flow in from at least an inlet to the sensor so as to provide representative samples of the fluids before the fluids return after flowing through at least an outlet.

Description

[0001] Statement of Government Rights [0002] Under the terms of Contract No. DE-FC26-01NT41103 awarded by the Department of Energy, the U.S. Government may have a paid license to this invention and may have the right, with limitations, to require the patent owner to license others to practice the invention on reasonable terms . technical field [0003] The present invention relates to systems and methods for improving the performance of sensors for monitoring the exhaust gas of internal combustion engines. These gas or fluid sensors include exhaust sensors and soot sensors. Background technique [0004] Exhaust gas sensors and other fluid sensors are used to control and monitor internal combustion engines, including vehicles powered by gasoline or diesel fuel and using various engine technologies such as lean combustion. Various types of gas or fluid sensors may include, for example, heated exhaust gas oxygen (HEGO) sensors or lambda sensors, universal exhaust gas oxyge...
