Abstract [en]

In this time of environmental awareness and corporate social responsibility, it is vital for companies to offer environmentally friendly products or services in order for the companies to be competitive. Being one of the largest truck manufacturers in the world, Volvo Trucks is obligated to follow this trend. The biggest drawback with a truck in an environmental perspective is its pollutants and carbon dioxide emissions. A major variable when reducing emissions is the fuel consumption. Trucks are used for transport and run day and night, often for very long distances. It is safe to say that even a very small reduction in fuel consumption has a major impact on both the fuel economy and the environmental impact over the truck's lifetime.

This report consists of a comparison made of a fixed coolant pump and a 2-speed clutch pump. A fully variable clutch pump was also meant to be tested but was not, due to limited resources. The aim was to determine the best alternative to proceed with regarding fuel economy, which is the ultimate goal for Volvo Trucks.

The test results are not reliable because of major mechanical errors due to flaws in the test equipment used. This report works as a basis for continued research regarding clutch performance. However, from the results given it is clear that a controllable coolant pump clutch is the right field of study to continue researching since it has great power saving possibilities.
