Dimethyl Ether (DME) can be liquefied at low pressure and can be easily stored in cylinders. Because of these characteristics, DME is suitable as an Automobile fuel. As diesel fuel, DME ignites when it is burnt because it contains oxygen. Therefore emission of NOx can be suppressed easily. Thanks to these characteristics, high expectations are placed on DME as a new fuel with low CO2 Emissions for heavy-duty vehicles. The Laboratory is undertaking research of a fuel injection technology, combustion control and other themes to acccelerate commercialization of DME.
Current status and problems to be solved regarding DME engines
*Spray and combustion characteristics are unsolved.
*The durability of fuel injection systems should be maintained.
