Polyoxymethylene dimethyl ethers are a class of ethers with the molecular structure CH3(-O-CH2)n-O-CH3, called OME for short. Amid a growing global trend for a carbon neutral, OME has attracted the attention as a potential e-fuel for compression ignition engines because it has good ignitability and low-sooting tendency. In this article, the fuel property, the synthesis, the cost, chemical kinetic mechanisms and the effects of OME blends on engine performance are described based on the latest literatures, as well as the research on the spray characteristics made by the authors. The points are as follows: it is not feasible to use neat OME because the cost of OME synthesis is high with the current technology, but to use as diesel fuel additive that can greatly reduce PM emission. Without changing the fuel injection strategy from diesel fuel, the thermal efficiency is penalized with OME blends. The ignition delay and combustion duration decrease with the increasing of OME ratio in the diesel fuel blends. The thermal efficiency could be improved by optimizing the fuel injection parameters.
