Ekodiesel – trade name for SMN 30
SMN 30 is high-quality environment-friendly alternative fuel for compression ignition engines produced by mixing of standard diesel fuel in accordance with EN 590 and fatty acid methyl esters (rapeseed oil methyl ester) in accordance with EN 14214. SMN 30 is a mixture of standard diesel fuel in accordance with EN 590 and rapeseed oil methyl ester where the content of rapeseed oil methyl ester amounts to at least 31 %.
Application
SMN 30 is suitable for use in all compression ignition engines that are approved for these purposes by the manufacturer.
Impact on engine characteristics (power)
As compared to common diesel fuel SMN 30 has an approx. 3-4% lower energy content, i.e. 3-4% lower engine power, which can hardly be recognized in normal operation.
Impact on the sealing and hoses of the fuel system
In new vehicles the use of SMN 30 does not represent any risk in this respect. In older vehicles (made in 1996 and older) visual check is recommended or replacement of formerly used incompatible materials after consultation with the manufacturer.
- SMN 30 has a reduced content of sulphur (max. 40 mg/kg)
- SMN 30 reduces total emissions of the combustion process (reduces the content of CO and HC in the exhaust gas) and smoke, i.e. soot as well, but it slightly increases NOx emissions. The run of the engine is quieter and softer.
- Approx. 30% of SMN 30 are obtained from renewable resources. Rape binds CO2 in the photosynthetic reaction before it is produced by subsequent combustion.
- SMN 30 is biodegradable – 90% in 21 days.
Miscibility with standard diesel fuel
SMN 30 is freely miscible with standard diesel fuel, so during refuelling you do not have to worry whether there is diesel fuel or diesel with added biological constituent in the tank.
Transition to operation with SMN 30
SMN 30 has cleaning effects in the fuel system and in the engine itself. In practice it means that it dissolved deposits caused by the operation with standard diesel fuel. Consequently, this is a positive phenomenon, but higher attention must be paid to the condition of the fuel filter, where these impurities are deposited and to the oil filter as during the dissolution of deposits in the engine a part of deposits released this way contaminates the engine oil and a part of the deposits is released in exhaust gases. Therefore, closer checks are recommended in both the systems.
Storage requirements
SMN 30 contains a biological constituent that is hygroscopic. If during unsuitable or long-term storage (more than 3 months) the water content increases, the fuel may deteriorate.
