It can be produced sustainably, and its combustion is clean and efficient. This study investigates the effects of different OME<sub>3-5</sub> 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 OME<sub>3-5</sub> and B7 diesel were applied with 0, 7, 15, 25 and 45 vol% OME<sub>3-5</sub> content at four loads. The NO<sub>x</sub>–PM trade-off was investigated at 11 EGR rates for each mixture at each load. Increasing OME<sub>3-5</sub> mixing ratio reduced the PM emission, improved the NO<sub>x</sub>–PM trade-off, and increased the brake thermal efficiency. The maximum achieved PM emission reduction was 86.8% for high loads. However, NO<sub>x</sub> emission increased, and also low heat capacity and viscosity can be a problem for real applications</p> ER -
