1. Simulation of road traffic flow in Hangzhou
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : Is it possible to increase traffic flows and decrease stand stills in rush hour traffic by tweaking existing traffic light signals? A vehicle’s engine running on idle is not useful in physical terms and emits unnecessary exhausts. By investigating and observing signal phase times on site in Hangzhou, China, an effort was made to find out if it was possible to get better flow and thus lower emissions by changing the traffic signal programs.

2. Investigation into Urea Deposit Risk by varying parameters in the control system related to urea evaporation
University essay from KTH/KemiteknikAbstract : I och med nuvarande och kommande lagkrav för utsläpp från tunga lastbilar finns en efterfrågan på utvecklade strategier för utsläppsminskning. För att kontrollera utsläppen av kväveoxider (NOx) används katalytisk omvandling med AdBlue (vätskeblandning av urea och vatten). READ MORE

3. Model Predictive Climate Control for Electric Vehicles
University essay from Uppsala universitet/Avdelningen för systemteknikAbstract : This thesis explores the possibility of using an optimal control scheme called Model Predictive Control (MPC), to control climatization systems for electric vehicles. Some components of electric vehicles, for example the batteries and power electronics, are sensitive to temperature and for this reason it is important that their temperature is well regulated.

4. Automatic detection of the fuel composition in a Diesel Engine : Identifying fuel composition in the fuel system of a combustion engine and optimising for computational complexity
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : The transportation industry is responsible for 26% of all emission of greenhouse gases in the European Union. Many steps are being taken to minimise greenhouse gas emissions. The most effective way to reduce the emission of greenhouse gases is by transitioning to biofuels. READ MORE

5. Identifying risks of AdBlue spray on stainless steel surfaces
University essay from KTH/KemiteknikAbstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE
