Exhaust Gas Sensor

The exhaust gases of automobiles causes many serious health and environmental issues. The existing challenge is to reduce the released unburnt fuel and to create a smart fuel injection control which will result in better performance and fuel efficiency. This can be made possible only with the ability to sense and analyze the exhaust in real time. The objective of the project is to develop an integrated exhaust gas sensor using MEMS technology. It can sense four main harmful constituents of the exhaust gases from an automobile. The gases that can be sensed are Nitrogen dioxide (NOx) and Hydrocarbons (HC) . The two gas sensors are integrated into a single package. The main sensing element is the micro cantilever used as a resonator. The measurement value of the change in the resonant frequency of the cantilever beam gives the amount of the corresponding gas present in the given sample. Simulation is done to derive the relation between the mass of the cantilever beam and its corresponding resonant frequency. COMSOL Multiphysics is the numerical solver used here. This design will also help us to design a real time exhaust gas monitoring system.
