6. Exhaust Temperature Modeling and Optimal Control of Catalytic Converter Heating
University essay from Linköpings universitet/FordonssystemAbstract : After reaching its light-off temperature, the catalytic aftertreatment system plays a major part in maintaining emissions at low levels for vehicles equipped with combustion engines. In this thesis, modelling of the exhaust gas temperature is investigated along with optimal control strategy for variable ignition and exhaust valve opening angles for optimal catalytic converter heating.

10. The Miller Cycle on Single-Cylinder and Serial Configurations of a Heavy-Duty Engine
University essay from KTH/FörbränningsmotorteknikAbstract : I jämförelse med sina föregångare, har moderna lastbilsmotorer genomgått en betydandeutveckling och har utvecklats till effektiva kraftmaskiner med låga utsläpp genom införandet avavancerade avgasbehandlingssystem. Trots att de framsteg som gjorts under utvecklingen av lastbilsmotorer har varit betydande, så framhäver de framtida förväntningarna vad gällerprestanda, bränsleförbrukning och emissioner behovet av snabba samt storskaliga förbättringar av dessa parametrar för att förbränningsmotorn ska fortsätta att vara konkurrenskraftig och hållbar.
