1. Simulations of compressible flows associatedwith internal combustion engines
Abstract : Vehicles with internal combustion (IC) engines fueled by hydrocarbon compoundshave been used for more than 100 years for ground transportation.During these years and in particular the last decade, the environmental aspectsof IC engines have become a major political and research topic.

2. Numerical Studies of Flow and AssociatedLosses in the Exhaust Port of a Diesel Engine
Abstract : In the last decades, the focus of internal combustion engine development has moved towards more efficient and less pollutant engines. In a Diesel engine, approximately 30-40% of the energy provided by combustion is lost through the exhaust gases. The exhaust gases are hot and therefore rich of energy. READ MORE

3. On the Agglomeration of Particles in Exhaust Gases
Abstract : Particulate emissions from road transportation are known to have an adverse impact on human health as well the environment. As the effects become more palpable, stricter legislation have been proposed by regulating bodies. READ MORE

4. On Gas Dynamics of Exhaust Valves
Abstract : With increasing effects of global warming, efforts are made to make transportationin general more fuel efficient. When it comes to internal combustion engines,the most common way to improve fuel efficiency is through ‘downsizing’. Downsizingmeans that a smaller engine (with lower losses and less weight) performsthe task of a larger engine. READ MORE

5. High Temperature Corrosion of Cast Irons and Steels
Abstract : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. READ MORE
