The purpose of this paper is to analysis the performance of an oxygen sensor using computational fluid dynamics (STAR-CD), and is based on scalars concentration around sensor element and static/dynamic performance data of oxygen sensor. The analysis uses transient boundary conditions, supplied by GT-Power software to approximate the real life utilization, and various velocities and loads were run to obtain the overall oxygen sensor dynamic performance. In this study, was analyzed the scalar concentration from each cylinder around the element sensor, simulating the oxygen sensor dynamic response outputs.
