Ladungswechsel- und Verbrennungsoptimierung schnellaufender Zweitakt-Dieselmotoren zur Reduzierung der Laerm- und Abgasemissionen und des Betriebsstoffverbrauches Schlussbericht

Abstract

Two stroke diesel engines are established as being the most efficient prime movers (e.g. they are the main propulsion technology used in large marine vessels). This technology is not yet available in smaller sizes. Therefore the main principles of fast running, turbocharged, two-stroke diesel engines have been investigated in the project 'Optimisation of Scavenging, Combustion and Emissions of fast running Two-Stroke Diesel Engines' in order to achieve significant improvements of the efficiency while reducing emissions. In many steps the engine components involved in these fields of interest have been optimised in their design as well as tested on elaborate bench tests. Thereby an improvement of consumption, scavenging, combustion and emissions could be achieved. Along the possible use in the field of general aviation, these results might be applicable to other fields; a reduction of emissions and consumption are not only interesting in their use for two stroke diesels. Individual results, e.g. the improved injection or turbocharging might very well benefit the further development of four strokes engines.
