a study of producers using forestry- or agricultural sector feedstock
… still increasing the emissions of carbon dioxide and other green house gases. Diesel fuel represents one of the fuels that contributes to these emissions and the use of diesel fuels is increasing every year. The main purpose of this study was to make an estimation of the current …
Problem Discussion: Nissan Diesel became a part of the Volvo Group in the end of March, 2007. A year has passed and the integration process is making progress but it is perceived to lack some momentum. Our sponsor would like to understand if there are any potential barriers to …
A one-cylinder research engine has been used for studies with a Diesel Dual Fuel concept (DDF). DDF is a concept that utilizes a pilot diesel injection to ignite a homogenous natural gas/air mixture. Emissions and engine efficiency have been analyzed in an emission cycle called …
When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of …
The work covered in this report includes a literature study of the diesel dual fuel technology (hereinafter referred to as DDF). The literature study covers earlier work that has been done regarding the use of compressed natural gas (CNG) and diesel in a DDF system. Moreover a …
… av katalytisk förbränning. Anläggningarna i Kina har ett skrubbertorn med diesel följt av en aktiv kolbädd som polersteg. Anläggningarna i USA har en katalytisk förbränningsmetod kallad Oxidizer. Teknikerna jämförs och utvärderas utifrån teknik, miljö och ekonomi i rapporten …
… of this project was the development of a Multi-zone model for NO xformation in Diesel engines. Because of the stringent emission legislations, great effort is made to decrease the fuel consumption and the harmful emissions of internal combustion engines. Computer simulations …
Diesel electric propulsion is in many ways a good alternative to conventional shaft propulsion, both economically and environmentally. There are also many other good side effects which need to be considered, i.e. better manoeuvrability, more efficient use of space and less noise …
Vilket alternativt drivmedel uppfyller bäst Försvarsmaktens behov?
… insecure. The alternative fuels that are described and compared are; Synthetic diesel, Organic diesel, Methanol and Ethanol. The essay describes the process of producing the alternatives, the need for modification and the economics for each alternative. The alternatives are …
Optimerad internkommunikation
… communication. We have done qualitative interviews with McDonald’s and Diesel, two different global organizations within the branch of service business. All respondents work in strategic positions. We want to emphasize how organizations with structural differences adjust their …
… koldioxidemissioner från vägtrafiken genom att först uppskatta mängderna diesel, från ett kritiskt perspektiv. Som hjälp till detta har en alternativ metod, för att uppskatta dieselkonsumtionen från vägtrafiken i Sverige, skapats. Resultaten visar skillnader mellan olika …
Från idé till prototyp
This thesis describes the development of a tank insert for diesel cars, from idea to a prototype. The idea is to design an insert which makes it impossible to refuel petrol in a diesel car. The insert shall be installed in the existing tank opening on diesel cars. The tank …

… been exposed to theft or vandalism. The most common stolen goods were: 1. Diesel (51 %) 2. Tools (47 %) 3. Electronic (20 %) 4. Workshop equipment (19 %) 5. Other equipment (11 %) Vandalism mostly occurs during attempted thefts, locks and doors are often damaged during a theft …
… energy for the buildings. Four energy producing systems (aquifer, rape seed diesel generator, snow-cooling and air blast cooler) are compared with today’s systems (districts heating and compression cooling machines) with respect to environmental impact and economy. District …
En studie om vilka tekniska lösningar dieselmotorutvecklande företag använder för att bemöta existerande och framtida miljökrav
… tekniska lösningar dessa företag nyttjar för att producera miljövänligare dieselmotorer samt vilka metoder de anser vara lämpliga för framtida forskning. Rapporten innefattar dessutom en undersökning huruvida åkerier/bussbolag/privatpersoner som använder dessa företags …
