This report describes the development of a web site for co-workers on leave of absence at Volvo Cars Engine AB and graduated students at Volvo Upper Secondary School in Skövde. The aim of the web site is to be a complement to existing communication channels in the promotion of the contact between the target group and the company. The work was divided into two parts; the first consisting of a preliminary study used to identify the information which the target group finds absent in their absence from their place of work/school, and the second part consisting of the development of a proposition of content layout and web site design. The finished proposition was presented along with a couple of alternatives for the technical implementation. The information department at Volvo Cars Engine AB in consultation with Volvo Cars IT will carry on the implementation, administration and further development of the proposed solutions..

The engine of JAS 39 Gripen, RM12, has recently been equipped with a new flameholder and a new engine inlet. This change has caused an increased noise level from the engine when the afterburner is in use. The noise level reaches its peak when the afterburner is partially used. The problem is thought to be unstable combustion in the regions around the flameholder. A solution to the problem has been proposed by Volvo Aero.

Rapporten betraktar energisystemen vid Göteborg Energi (GE) och Volvo Cars, Torslanda. De två systemen integreras som ett system och inverkan av olika åtgärder betraktas. Huvudsyftet är att minska systemkostnaden för det totala systemet.Arbetet är genomfört med kraftbonusmetoden, en marginalsyn på el där all ny elproduktion beräknas ersätta kolkondensproducerad el. Allokeringen för utsläpp vid kraftvärmeproduktion är också beräknad med kraftbonusmetoden.För simulering har optimeringsprogrammet Modest använts. En konstruktion av datormodeller av energisystemen vid Göteborg Energi och Volvo Cars har gjorts.

We can see an increasing middle age population in large parts of the world. People are healthier when they retire than they were before. As people grow older, physical and mental changes occur that can make the use of cars more complicated. The possibility to travel by car is important for many people to keep the connection with the society and to feel independent. How can Volvo cars face the needs of this growing target group?The purpose of this project is to make a car concept that responds to those needs, it is therefore important to maintain the values of Volvo cars.

Den här rapporten är ett examensarbete utfört för Volvo Cars Uddevalla vid Linköpings tekniska högskola. Vår uppgift har varit att hjälpa Volvo Cars Uddevalla med att starta arbetet med energieffektivisering. Det gör vi genom att undersöka vilka möjligheter till energieffektiviseringar som finns för att minska framförallt elanvändningen. Vi har föreslagit ett antal effektiviseringsåtgärder genom att titta på de mest energiintensiva processerna på fabriken och målet för elanvändningen är att minska den med 50 procent.Effektiviseringsåtgärderna har tagits fram genom att leta systemfel, som i princip alltid finns inom ett företag, och genom att undersöka om icke elspecifika processer kan konverteras till bränslen. Det är framförallt stödprocesserna som undersökts eftersom det oftast är bland dem de största systemfelen finns.En uppskattning har slutligen utförts för hur stor energianvändningen blir efter genomförda förändringar.

Volvo Cars in Skövde manufacture and assemble Volvo engines. When attaching the ignition coil to all 4-cylinder engines, a special mounting tool is required. This mounting tool is currently manufactured from injection-molded polyoxymethylene (POM), a thermoplastic. It has been noted that the life span of the tool is shortened as a result of abrasive wear that occurs during the attachment process of the ignition coil.An investigation of the possibility of manufacturing the mounting tool with a 3D-printer is undertaken in cooperation with ÅF, a consultant to Volvo Cars. A literature study is first presented to introduce broader knowledge on the subject.

By using steady-state measurements for predicting emissions under a dynamic drive cycle wouldsave a lot of time and money for the exhaust aftertreatment specialists at Volvo cars. The idea forthis thesis has been to investigate if statistical regression models can be used with good accuracy.Questions included are for example if common operating variables such as engine speed, air-fuelratio etc. is sufficient to predict engine-out emissions over the engine operating range with goodaccuracy. Focus was set on the modelling of warm engine, but also the more complex engineheat-up phase was investigated since it is a great contributor to total emissions. While NOxcouldnot be measured because of malfunctioning measurement equipment, only HC, CO andtemperature at inlet of first catalytic converter has been modelled.

AbstractStudents at Mälardalen University have long performed their lab on a small turbojet engine in the course Aircraft Engine Technology. Since 2011, the engine has been dysfunctional. This was due to lack of maintenance. Since the lab has been an important element in teaching, the University had decided to get the engine functional again. This thesis project has been a request of Mälardalen University.The task we were assigned to was:1.

Vilka effekter ger särskilda insatser till personer som är uppsagda till följd av varsel? Denna uppsats syftar till att undersöka effekterna på återgång till arbete av extra-insatta utbildningar som syftade till omställning vilka fanns tillgängliga för de som varslades vid Volvo Cars och dess underleverantörer 2008/2009. Effektutvärderingen utgår ifrån överlevnadsanalys där projektgruppen matchas mot en kontrollgrupp bestående av samtliga övriga varslade i Sverige. Resultaten visar att gruppen som tog del av utbildningsinsatserna hade signifikant långsammare återgång till arbete jämfört med en matchad kontrollgrupp..

This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.

This report describes the results of the project "Concept development of jet engine inspection plugs" carried out in the spring of 2008. The work was done at the department of product definition at the company Volvo Aero in Trollhättan. The objective of the work was to develop concepts for a "Volvo-unique" inspection plug. The work is part of Volvo Aero's focus on proprietary (self-developed) technologies. Inspection plugs can be found on virtually all aircraft engines and gas turbines.

The aim of this thesis is to map the current internal information flow at Volvo Uddevalla, to detect obstacles in the flow and to find out how these obstacles can be avoided. The aim is also to describe how a corporation, in this particular case Volvo Uddevalla, creates knowledge and use information. The study is performed in order to create a base for the coming implementation of a new information standard. The method used is conducting an information audit investigating the current management of documentation according to the changes that have to be made to carry out the claims from the standard. The investigation is made by way of interviews with 16 of the employees at Volvo Uddevalla.

Demands on businesses are constantly increasing and the competition in the market-place is becoming ever tougher. To gain the long-term confidence of customers, not only the best businesses, but also the best supply chains are required.Volvo Cars is experiencing a changing competitive situation and their retailers are having trouble stocking the right spare parts. Shorter product life cycles and the growth of Volvo?s product program result in an increase in the number of spare parts to be stocked. In order to adapt to market trends and meet customer demands, Volvo has developed the LDC model, establishing a number of regional warehouses in strategic locations in Sweden, de-signed to supply spare parts to the regions? retailers through so-called Vendor-Managed In-ventory (VMI).The purpose of the study is to examine Volvo personbilar Sverige?s (VPS) motivation for a modified customer-service strategy through LDC.
