BEFORE YOU OPERATETNV Operation Manual 33DIESEL FUELDiesel Fuel SpecificationsDiesel fuel should comply with the followingspecifications. The table lists several worldwidespecifications for diesel fuels.Additional Technical Fuel Requirements• The fuel cetane number should be equal to 45or higher.• The sulfur content must not exceed 0.5% byvolume. Less than 0.05% is preferred.• Bio-Diesel fuels. See Bio-Diesel Fuels onpage 33.• NEVER mix kerosene, used engine oil, orresidual fuels with the diesel fuel.• Water and sediment in the fuel should notexceed 0.05% by volume.• Keep the fuel tank and fuel-handling equipmentclean at all times.• Poor quality fuel can reduce engineperformance and / or cause engine damage.• Fuel additives are not recommended. Somefuel additives may cause poor engineperformance. Consult your Yanmarrepresentative for more information.• Ash content not to exceed 0.01% by volume.• Carbon residue content not to exceed 0.35% byvolume. Less than 0.1% is preferred.• Total aromatics content should not exceed 35%by volume. Less than 30% is preferred.• PAH (polycyclic aromatic hydrocarbons) contentshould be below 10% by volume.• Metal content of Na, Mg, Si, and Al should beequal to or lower than 1 mass ppm. (Testanalysis method JPI-5S-44-95)• Lubricity: Wear mark of WS1.4 should be Max.0.018 in (460 μm) at HFRR test.Bio-Diesel FuelsIn Europe and in the United States, as well assome other countries, non-mineral oil based fuelresources such as RME (Rapeseed Methyl Ester)and SOME (Soybean Methyl Ester), collectivelyknown as FAME (Fatty Acid Methyl Esters), arebeing used as extenders for mineral oil deriveddiesel fuels.Yanmar approves the use of bio-diesel fuels thatdo not exceed a blend of 5% (by volume) ofFAME with 95% (by volume) of approved mineraloil derived diesel fuel. Such bio-diesel fuels areknown in the marketplace as B5 diesel fuels.These B5 diesel fuels must meet certainrequirements.1. The bio-fuels must meet the minimumspecifications for the country in which theyare used.• In Europe, bio-diesel fuels must comply withthe European Standard EN14214.• In the United States, bio-diesel fuels mustcomply with the American Standard ASTMD-6751.2. Bio-fuels should be purchased only fromrecognized and authorized diesel fuelsuppliers.Precautions and concerns regarding the useof bio-fuels:1. Free methanol in FAME may result incorrosion of aluminum and zinc FIEcomponents.2. Free water in FAME may result in plugging offuel filters and increased bacterial growth.Diesel Fuel Specification LocationNo. 2-D, No. 1-D, ASTM D975-94 USAEN590:96 European UnionISO 8217 DMX InternationalBS 2869-A1 or A2 United KingdomJIS K2204 Grade No.2 JapanKSM-2610 KoreaGB252 China
