Today, diesel cars and vehicles are increasingly equipped with DPF to meet new, stringent emission legislation. Those metals will accelerate the aging process and will contribute to higher sediments.

During long-term storage FAME biodiesel have a “use before” date. (WWFC 2009).Disclaimer: The AMF TCP is organised under the auspices of the International Energy Agency (IEA) but is functionally and legally autonomous. %%EOF 2011).Two forms of stability are important for biodiesel fuels; one is stability during long-term storage and the other relates to stability while the fuel is subjected to high temperatures and/or high pressure, as is the case with an engine’s fuel injection system.FAME in diesel fuel presents risk on engine durability. As biodiesel it is most likely to hold a higher water content than other petroleum-based fuels which can increase the chances of fuel contamination and other serious complications. 2011).As polar compounds FAME esters dissolve materials more efficiently than diesel fuel and this may lead to material compatibility problems. Fatty acid methyl ester (FAME) or biodiesel is a biofuel produced by transesterification of vegetable oils. The British Standard specification for Diesel allows a maximum FAME content of up to 7 vol.% (B7). FAME in diesel fuel presents risk on engine durability. Infrared spectroscopy is ideally suited to this measurement as FAME has a strong infrared absorption at around 1745cm-1 due to the ester carbonyl bond. Helps keep your MTN DEW® GAME FUEL® fresh and your hardware dry so you can focus on grinding Pull tab up. (Mikkonen et al. FAME biodiesel cannot be blended with diesel fuel in high concentrations without substantial risks for fuel quality, engine operation, exhaust emissions and infrastructure. 39 0 obj <> endobj Standards organizations in various countries have been struggling for some time now with the process of establishing a 20% FAME standard. No-Harm Test - FAME as Fuel Component. These elements may cause filter plugging and engine deposits.Biodiesel esters are high-boiling compounds, which may lead into fuel dilution of the engine oil especially in engines using post-injection for particulate filter regeneration. 2008).When blending diesel fuel, paraffins (HVO/XTL) and FAME, the following instructions should be followed: diesel fuel and paraffins are mixed first, and then FAME is added into blend. Fame. the verification of FAME content in diesel fuel blends. However, even a small amount of methanol remnant lowers the flash point rapidly. In addition, low flash point may lead to decreased lubricity, corroded injectors and degraded materials in the vehicle and fuel distribution system (WWFC 2009).FAME biodiesel is in principle compatible with the current vehicles, logistic systems and practices, however, stability issues are challenging. Guideline handling marine fuels with FAME V1.0, 2013 CIMAC 6 5.2.7 Monitor fuel filter condition for any increased rate of clogging by checking for increased back pressure or any increase in the automated back-flushing cycles. The high boiling range of FAME results in fuel condensation on the cylinder walls when fuel is injected late in the working cycle. Injection performance and cold-start properties of FAME may be poor.
Essentially, the B100 standard has been redesigned so that it is “protective” of the B20 and lower blends. (IEA-AMF Annex 34-1 McGill et al.

Many engine and vehicle manufacturers have taken this into account, but for many cars and vehicles problems may occur.
Therefore maximum limits for blending of FAME are defined in many regions.
FAME (Fatty Acid Methyl Esters) is the generic chemical term for biodiesel which is mostly produced from recycled cooking oils and renewable oil sources. The reason is due to poor oxidation stability that causes the fuel to biodegrade over time. FAME biodiesel should not be stored in systems that contain copper, brass, bronze, lead, and tin. That specification moved closer to reality in early 2007 when new limits in ASTM D6751 were approved for oxidation stability and other parameters for the 2007-2010 diesel engines. In biodiesel esters, for example, K, Na, P, glycerides, and glycerine may be present originating from feedstock and catalysts used in production of the biodiesel. ]��C�v%ć�4�@PH���@��.� h�bbd``b`Z$�C�`s��] ���� FAME may cause problems also at low concentrations, for example, deterioration of oil quality, clogging of particulate filters and dissolving materials.
