Motorprozessverhalten und Abgasemissionen alternativer Kraftstoffe im Vergleich mit Dieselkraftstoff

Vor dem Hintergrund einer verstarkten Diskussion um Treibhausgasemissionen und endlicher fossiler Energieressourcen beschreibt der folgende Beitrag der Universitat Rostock mogliche Potenziale moderner Diesel motoren mit Direkteinspritzung bei Einsatz von alternativen Kraftstoffen der ersten und zweiten Generation. Im Fokus herausfordernder Emissionsziele wird der Schwerpunkt hierbei auf die Abgasemissionen, speziell auf vergleichende Mutagenitatsunter suchungen der organisch loslichen Partikelfraktion gelegt.

Development and investigation of a gas engine for agricultural machinery

In addition to efficiency and greenhouse gas reduction potential, natural gas in terms of pollutant emissions offers significant advantages compared to diesel and gasoline fuel (Figure 1). Through the gaseous state, natural gas makes possible a very homogeneous mixing with the combustion air, resulting in a nearly soot free combustion. Also the emissions of ozone-forming nitrogen oxide emissions (NOX) and non-methane hydrocarbons (NMHC) can be reduced significantly through the use of a gas motor.

Engine Process Behaviour and Exhaust Emissions Alternative Fuels Compared with Diesel Fuel

Against the background of increasing discussions about the emission of greenhouse gases and limited fossil energy resources this contribution describes the potential of modern direct-injection diesel engines operated on 1st and 2nd generation alternative fuels. Focussing on demanding emission goals, the exhaust emissions and especially comparative mutagenicity research of the soluble organic particulate fraction are at the centre of this paper prepared by the University of Rostock.
