1. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring
Sammanfattning : While the car fleet becomes increasingly larger it is important to lower the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from high NOx emissions and particulates, in the case when diesel is utilized, and emissions at cold start from gasoline engines. LÄS MER
