Challenges in Powertrain Internal Combustion Engine
One challenge in automotive engine design is to achieve a fast start-up time (under five seconds) of the oxygen (O2) sensor without compromising part life due to overheating. Typical start-up time is about eight seconds for current designs.
Engineering Solution
The solution to this particular issue requires a multiphysics numerical approach. The workflow will involve one-way transient electrical and thermomechanical coupling using Ansys Icepak and Mechanical software as shown below.

The goal is to ensure optimal balance between sensor heat-up and part life.
Ansys Solution Benefits
The Ansys workflow is easy to use, and enables comprehensive multiphysics simulation while supporting parametric design optimization (OptiSlang) of various design considerations. The temperature dependent resistivity and transient effects are captured in the model.
