1. 1. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring

   Författare :Helena Wingbrant; Anita Lloyd-Spetz; Karin Larsson; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; field effect sensor; gas detection; selective catalytic reduction; lambda; cold start; ammonia; silicon carbide; engine exhaust.; Physics; Fysik;

   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
