   Sammanfattning : This thesis investigates the use of cylinder pressure measurements for estimation of the in-cylinder air/fuel ratio in a spark ignited internal combustion engine. An estimation model which uses the net heat release profile for estimating the cylinder air/fuel ratio of a spark ignition engine is developed. LÄS MER

3. 2. Silicon carbide field-effect devices studied as gas sensors for exhaust gas monitoring

   Författare :Peter Tobias; Ignaz Eisele; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; silicon carbide; high temperature; gas sensors; field effect devices; MISdevices; Schottky diodes; experimental design; reaction kinetics; mass transport; car exhaust; multipoint injection; response times; cylinder specific; on-board diagnosis;

   Sammanfattning : Metal-insulator-silicon carbide (MIS) structures have been studied as gas sensors. We have investigated how the sensors detect gases, how fast they do that, and how they could be used for exhaust gas monitoring.We have prepared simple field-effect devices, MIS-capacitors and Schottky diodes, on silicon carbide with platinum gates.

4. 3. Combustion Sensing Methods - in Theory and Practice

   Författare :Martin Larsson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal combustion engines; HCCI; combustion measurements; measurement techniques; SI; signal processing; pressure sensors; ion current sensors;

   Sammanfattning : Accurate, reliable sensors are essential parts of any control system, and there are increasing needs for feedback systems to monitor and control key parameters of automotive internal combustion engines, operating in various combustion modes and configurations, to reduce fuel consumption and engine-out emissions. Thus, there are strong motives for studying combustion sensors. LÄS MER

5. 4. Data-Rich Multivariable Control of Heavy-Duty Engines
