'''DME'''
Digital Motor Electronics (DME) is a microprocessor-based system that controls the ignition, the fuel injection, the oxygen sensor and numerous ancillary functions. DME provides raw data to an on-board computer that uses an alphanumeric display to provide you with information such as the average fuel consumption, the distance you can still cover with fuel in the tank, an average speed, outside temperature and more.

The core of a DME [[application]] are [[microprocessor]]s. [[Microprocessor]]s work at astonishing speeds. The core of central engine management in the current [[BMW]] M3 executes nearly twenty million instructions per second (20 MIPS). [[Microprocessor]]s also have a reputation for being extremely reliable. They are designed for a lifespan of at least 150,000 active hours. A car by comparison, is expected to survive 4,000 hours of use.




'''The abbreviation '''DME''' can has several other meanings:'''

* [[Dakota, Minnesota and Eastern Railroad]], a railroad in the [[United States|US]] {{reporting mark|DME}}
* [[Distance Measuring Equipment]], a [[transponder]]-based [[radio]] [[navigation]] technology .
* [[Dimethoxyethane]], a [[solvent]].
* [[Dimethyl ether]], a [[Fuel|fuel]] and an [[aerosol spray#Propellant|aerosol spray propellant]].
* [[Direct Machine Environment]], an old operating system for the [[ICL2900]] series computing system from [[International Computers Ltd]].
* DME is the [[IATA]] code for [[Domodedovo International Airport]], one of the airports serving [[Moscow]], Russia.
* Dry [[Malt]] Extract used in the [[brewing]] of [[beer]].
* DME was a popular, fully customizable text editor for the Amiga computer. It can still be found on the [http://wuarchive.wustl.edu/pub/aminet/info/www/home.html Aminet] software archive.
