    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Heat Transfer; CFD; Internal Combustion Engine; Diesel; PPC;

    Abstract : Popular Abstract in Swedish Transporter är viktiga för ett fungerande samhälle, men samtidigt innehåller avgaserna från en förbränningsmotor farliga utsläpp som förorenar vår miljö. Kan vi på något sätt hindra att miljön blir förstörd av farliga utsläpp genom förbättrad motordesign? Frågan om global uppvärmning har varit vid liv enda sedan IPCC (Intergovernmental Panel on Climate Change) grundades och Kyoto-protokollet infördes, vilket har lett till kännedom om växthusgaser och deras inverkan på jordens temperatur.
