The Application of E-Fuel Oxymethylene Ether OME1 in a virtual Heavy-Duty Diesel Engine for ultra-low Emissions
For long haul transport, diesel engine due to its low fuel consumption and the low operating costs will remain dominant over the long term. In order to achieve CO2 neutrality, the use of electricity-based, synthetic fuels (e-fuels) provides a solution. Especially the group of oxymethylene ethers (OME) is considered promising for its soot-free combustion. The new fuel properties and combustion characteristics place new demands on engine design and also open up new degrees of freedom to operate diesel engines. In this work, the effects of dimethoxymethane (OME1) were investigated by means of 1D simulation at three different operating points on a virtual truck diesel engine. The subsystems of fuel injection, air path and exhaust gas were sequentially adjusted for the purpose of low emissions, especially low nitrogen oxides (NOx).
