30 Credits - Test method development within flow distribution and urea vaporization
30 Credits – Test method development within flow distribution and urea vaporization, Exhaust aftertreatment performance
Introduction
A thesis project at Scania provides an excellent way of getting to know the organization and to create your own network. Many of our current employees started their career with a thesis project. If you would like to be a part of a great team with established knowledge on exhaust aftertreatment system and contribute to the understanding of future demands for the existing products, you are welcome to challenge yourself with this thesis project.
Background
Scania thrives to be a leading company, both with its existing and developing products, for current and future dexmands to achieve low to zero emissions. For internal combustion engine vehicles, achieving low emission relies heavily on the efficiency of the exhaust after treatment system. Urea vaporization and flow distribution is integral part of aftertreatment performance and integrated part of the driveline, and both influences and is influenced by the engine. We involve in testing, evaluating, optimizing and calibrating the exhaust aftertreatment, both as a system and on a component level. Most of the work is done in engine test cells, but testing is also performed in rig, truck and bus.
Objective
The objective of this work is to gain an understanding of ammonia flow distribution within aftertreatment performance and develop a specific test method to improve the efficiency of the system to fulfill the upcoming legislation requirements and also create more value for our end customers.
Job description
The thesis work should include:
• A literature survey of different methods used in ammonia flow distribution in aftertreatment system.
• A deep analysis of current methods used within Scania
• Develop a new programmable hardware configuration to measure flow distribution with the support from our colleagues and documentation of the work
• Developing new and/or optimizing the current ammonia distribution measurement method
• Evaluation of the developed method on flow test rig and/or engine test cell
Education/program/focus
The ideal thesis student has a high degree of logical thinking, absorbs new knowledge, shows initiative, works in a systematic way and takes new social contacts with ease. We believe the student has grades (with honors) in one or more of mechanical engineering, Chemical engineering, combustion engine technology , energy technology and/or mechatronics. Previous experience on aftertreatment system, testing, simulations, programming (MATLAB /Python/LabVIEW) and data analysis is advantageous
