Potenziale elektrischer Zusatzaufladung mit neuen Regelungskonzepten

Die heutigen Entwicklungstrends im Bereich der Fahrzeugantriebe werden masgeblich durch gesetzliche Reglementierungen von Schadstoff- und CO2-Emissionen und Kundenanforderungen betreffend Fahrspas, Image und Sparsamkeit getrieben.

Oxymethylene ether (OME1) as a synthetic low-emission fuel for DI diesel engines

In long term the greenhouse gas (GHG) emissions have to be reduced stringently. One way to achieve this goal is the substitution of fossil fuels through CO2-neutral fuels. There are gaseous and liquid fuels possible to use. Liquid fuels have advantages in terms of logistics, energy densitiy and conventional storage technology. Fuels from biomass are critically evaluated because the savings in greenhouse gas emissions remain marginal considering the changes in land use and bring significant degradation of fuel quality with it. [1,2] An EU study including the indirect land use changes (ILUC) shows that Biodiesel leads to a CO2 increase of 9 to 20 %, compared to using mineral oil-based diesel fuel. [2]

OME in the Diesel engine – a concept for CO2 neutrality and lowest pollutant emissions

Currently the internal combustion engine is heavily criticized and associated with the poor air quality in a few german metropolitan areas and the progressive climate change, because of pollutant and greenhouse gas emissions. The engine development is under great pressure to meet the stringent CO2 reduction targets of the Paris Agreement of 2015. The defined goal is almost equivalent to eliminating CO2 emissions in the transport sector.

Oxygenate-fuel in a diesel engine – Is a CI engine capable of Lambda 1?

With an ever-increasing demand for fuel and a scarcity of existing crude oil resources as well as a desired elimination of greenhouse gas emissions in the transport sector by 2050, research on alternative fuels is gaining in importance. In addition to the further development of combustion engines and their exhaust gas aftertreatment systems, particularly climate-neutral fuels and their production offer great potential for fulfilling the CO2 emission and pollutant emission requirements.
