With clean burn characteristics,
Dimethyl ether (DME) is proving to
be an economic and effective
alternative fuel or fuel additive for
use with gas turbines as well as petrol
and diesel powered engines.

However, the seals used on diesel
engine injector tips must be specified
to resist degradation where a fuel
such as DME is used.

The operation of diesel engines
powered by DME
fuel for
commercial
passenger
transportation,
with DuPont
Kalrez 6375 Oring
seals fitted
to the fuel
injectors, has
achieved reliable engine performance
without premature seal degradation.

The broad chemical resistance of the
Kalrez parts, coupled with their high
temperature compatibility is said to
have enabled an improvement in
engine performance and extended
operating life.
