Abstract [en]

Exhaust after treatment technology based on a reductant (urea) injection into the silencer, has been set up to be a very efficient tool to reduce the emission of the Engines especially NOx. The reductant is stored in a tank positioned on the truck chassis. The reductant tank volume of today is required to be increased to meet the requirements of the market and that is motivated by Euro VI regulations which aim to a higher reduction of the emission of the NOx of the trucks. In this thesis the installation of dual reductant (Adblue) tanks on the truck chassis has been successfully setup. A proper method to transfer reductant from secondary to primary tank including a method to monitor the volume levels inside both tanks has been developed. Moreover, the installation of dual tanks deals with a liquid with a corrosive nature together with a truck that works in both cold and hot conditions, therefore there is a big challenge to come up with a concept robust enough. Also previous work in this area has been investigated to avoid the weaknesses for a developed solution. An air operated double diaphragm pump has been selected to transfer the reductant and an electromagnetic level sensor CAN-based type to monitor the reductant inside the tanks. Two concepts has been created, first is to flush the system after every transferring process and second is to warm up the pump. An implemented solution by a prototype has been validated by experimental results ended by final conclusion.
