Sensor Integrated Substrate for Future Exhaust System of Two Wheelers 2019-32-0617
By upcoming new global two wheelers emission legislation, it is expected that it will become more and more challenging to control exhaust emissions. Therefore, not only optimized catalyst specifications to meet OBDII or RDE, but also new components will be required for future applications in two-wheeler exhaust systems. In such applications, beneath applying new components, it is necessary to ensure mountability while maintaining vehicle design but improving function of the exhaust system at the same time. As exhaust system layout of two wheelers is generally strongly limited by many factors, such as steeply bended exhaust pipes and catalysts which are hard to resize, one of the most challenging tasks is the positioning of sensor behind the catalyst, due to two wheelers unique exhaust design. In order to overcome the challenge, this work describes designs like the catalyst with integrated lambda sensor, which is developed to contribute to high efficient future two wheelers exhaust systems.
