3. Approved Fuel
(a) In case of using biodiesel (only concentrations up to B20) fuel should comply with the below
recommended standards. However, raw pressed vegetable oils are not considered to be biodiesel
and are not acceptable for use as fuel in any concentration in this engine.
- En14214 (European standard) and/or ASTM D6751 (American standard). In North America,
biodiesel and biodiesel blends must be purchased from the BQ-9000 accredited producers and
BQ-9000 certified distributors.
(b) If the concentration is B7 or lower, it does not require any special preparations or operating
conditions. However, please strictly follow the standard operating conditions included in this
manual.
4. Conditions for the Operation with Biodiesel (above B7 through B20)
(a) The original service interval of the below stated services as indicated in this manual should be
halved:
- Replacement interval of the engine oil filter, engine oil and the fuel filter.
- Cleaning interval of the water separator.
- Draining interval of the fuel tank.
(b) Have the fuel injector inspected and cleaned every 1000 hours. It is strongly recommended to
replace the fuel hoses after 2000 operating hours or 2 years whichever comes first same as
conventional diesel fuel used.
(c) Replacement of the following parts before using the recommended biodiesel: (only for the
operation with biodiesel above B10 through B20)
- O-ring for the water separator (if fitted)
(d) Please use only biodiesel fuel that is appropriate to the intended operation environment of the
engines. This especially applies if the operating ambient temperature falls below 0 degree
centigrade.
(e) In particular, operation with biodiesel requires daily maintenance as follows:
- Please daily check the engine oil level. If the oil level rises above the oil level of the previous day,
the engine oil needs to be immediately replaced.
- Please daily check the water level of the water separator, If the water level rises above the “max”
indicator, an immediate drain of the water separator is required.
(f) Biodiesel blends up to B20 can only be used for a limited time of up to 3 months of the date of
biodiesel manufacture . Therefore biodiesel needs to be used at latest within 2 months from the
time of filling the tank or within 3 months from the time of production by the fuel supplier,
whichever comes first.
(g) Before a long-term storage without operating the engine, the biodiesel needs to be drained out
completely and the engine has to be run for 30 minutes with conventional diesel fuel.
