Dimethyl
Ether (DME)
Dimethyl
ether (DME) is a synthetic diesel fuel derived from natural
gas, an excellent candidate for direct injection engines.
DME contains no sulfur and burns more cleanly than conventional
diesel fuel, so it produces fewer particulates. It behaves
much like propane, and its cetane number is 55–60, up to 20%
better than modern diesel fuel. However, the viscosity of
DME is 10 times less than that of diesel fuel, which makes
it difficult to find pumps and valves that will not overheat or leak. Also, the entire
fuel system must be kept under a pressure of at least 5 bars
at room temperature to keep the DME liquid until it is injected.
