Effects of Oxymethylene Ether in a Commercial Diesel Engine
Oxymethylen Ether (OME) is a promising alternative fuel for diesel engines. It can be produced sustainably, and its combustion is clean and efficient. This study investigates the effects of different OME3-5 mixtures on emissions and combustion. The measurements were done on a four-cylinder common rail commercial diesel engine equipped with an exhaust gas recirculation system (EGR). Five different blends of OME3-5 and B7 diesel were applied with 0, 7, 15, 25 and 45 vol% OME3-5 content at four loads. The NOx–PM trade-off was investigated at 11 EGR rates for each mixture at each load. Increasing OME3-5 mixing ratio reduced the PM emission, improved the NOx–PM trade-off, and increased the brake thermal efficiency. The maximum achieved PM emission reduction was 86.8% for high loads. However, NOx emission increased, and also low heat capacity and viscosity can be a problem for real applications
