Engine Manufacturers Association releases test spec for biodiesel impact on engine performance, looking to baseline performance using B20 biodiesel blend.  ...

...   "The Engine Manufacturers Association (EMA) announced the release of a test specification for biodiesel fuel to facilitate testing and evaluation of how blended biodiesel fuels perform in today's clean-burning diesel engines. The EMA specifications establish technical requirements for blends of petroleum fuel and biodiesel fuel that can be used to assess the effects of such biodiesel fuels on engine performance, durability and emissions.  The EMA specifications – Test Specifications for Biodiesel Fuel – defines a biodiesel blend fuel with the properties and characteristics that engine manufacturers believe are needed to ensure good performance in today's engines. Engine manufacturers consider the specifications a critical and necessary first step in further testing and evaluating fuel blends with biodiesel content greater than 5%.

The EMA Test Specifications for Biodiesel Fuel establish a baseline B20 biodiesel blend that can be used for further testing and evaluation. EMA encourages vehicle owners interested in using biodiesel blends to request that the fuel meet the EMA specifications and that biodiesel fuel providers also produce blends meeting the EMA requirements and BQ 9000 production standards. Importantly, the EMA specifications are not an approved national fuel standard, and should not be used as such. "   ...
