2. Diesel Fuel Specifications
YT3 SERIES Maintenance | YT347, YT359
2.1. Diesel fuel regulation
Diesel fuel should comply with the EN590:96.
2.2. Additional technical fuel requirement
•
Sulphur content not greater than 10 mg/kg (15 mg/kg at point of final distribution)
• Cetane number not less than 45
2.3. Bio-diesel fuel
In consistency with other global diesel engine manufacturers and diesel fuel injection equipment manufacturers, YANMAR encourages the
development of renewable compression ignition fuels
and wishes to clarify our position on the use of biodiesel fuels in YANMAR Industrial Engines.
Non-mineral oil based fuel resources such as RME (Rapeseed Methyl Ester) and SOME (Soybean Methyl Ester), collectively known as FAME (Fatty
Acid Methyl Esters), are being used as extenders for mineral oil derived diesel fuels.
After YANMAR conducted the applicability evaluation, YANMAR approves the use of B7 (up to 7 % FAME) Diesel which shall not exceed a blend of 7
% (by volume) of FAME with 90 % (by volume) of approved mineral oil derived diesel fuel in YANMAR Industrial Engines.
YANMAR’s limited warranty conditions in case certain engines manufactured by YANMAR are operated with B7 Diesel are as follows:
1. YANMAR accepts the use of B7 Diesel only on the conditions that B7 Diesel must comply with “the European standard EN14214 and EN590-2009
(for Oxidation stability)” in Europe.
2. Please purchase B7 Diesel only from recognized and authorized diesel fuel suppliers.
3. Please use only B7 Diesel including methanol as the above relevant regulations state; otherwise, it may cause corrosion in aluminum and zinc
fuel injection equipment components.
4.
Please use only B7 Diesel contained certain water level as the above relevant regulations state; otherwise, it may cause fuel filters plugged and
also may increase bacterial growth.
5. Please use only B7 Diesel with low viscosity at high temperatures; otherwise, it may cause problems on fuel delivery, injection pump seizures
and poor injection nozzle spray atomization.
6. Please check the engine oil level daily. If the oil level rises above the oil level of the previous day, the engine oil needs to be immediately
replaced.
7.
Please check and confirm the quality of B7 Diesel and other fuel tanks before you will start to use it. Please keep daily maintenance during the
use of B7 Diesel and do not forget to regularly flush the fuel system and fuel storage containers. You may only use B7 Diesel at least within two
(2) months from the time of filling the tank or three (3) months from the time of production by the said fuel suppliers, whichever comes first.
YANMAR does not warrant and is not responsible for any problems caused by the use of the deteriorated B7 Diesel
or by the use of the B7 Diesel which do not comply with the above relevant regulations.
Consult your YANMAR tractor dealer before using the recommended biodiesel.
The engine of this machine uses precision parts in the fuel injection parts to comply with emission regulations.
When storing fuel to be used, avoid using containers made of zinc plated steel sheet, but use resin or stainless
metal containers. If the zinc or lead material melt into the fuel, it may cause engine malfunction.
