However, the bulk modulus of elasticity is too small for DME, and it is gaseity in normal temperature and pressure Although there were some problems to be solved if we wanted to apply the DME on diesel engine. All the problems summed up were how to choose injection system, considering the merits of the DME as well as how to modulate construct parameters of the system to adapt to the fuel.

但是二甲醚的弹性模量小，易压缩；常温常压下为气态等决定了它在柴油机上应用，需要选择一种适合该燃料应用的喷射系统，并对选用的喷射系统进行改造。
