Biodiesel is aggressive to some materials used in
fuel system components. Inspect seals, hoses,
rubber and plastic components every 10 hours.
Repair or replace any components that are
damaged, softened or leaking. Clean biodiesel from
painted surfaces immediately to prevent paint
damage.
Biodiesel is more sensitive to bacteria and water
contamination than distillate diesel fuel.
- Use as much fuel as possible before refilling the
fuel tank in order to prevent bacteria growth if a
machine is in regular use, e.g. regularly uses up
a tank of fuel within a week. In climates where
condensation is a risk, or when the machine is
working for short durations, keep the fuel tank full.
- Do not use biodiesel in machines with low
utilization or operating time.
- Do not store machines for more than 4 weeks
without flushing biodiesel out of the fuel system
by operating the machine through at least one full
tank of distillate diesel fuel.
- Always follow the manufacturer’s storage
recommendations and “best-before” dates for
each delivery of biodiesel.
Effects of biodiesel on exhaust aftertreatment
systems
Biodiesel leaves higher levels of ash in diesel
particulate filters and may require more frequent
diesel particulate filter (DPF) regeneration and
cleaning. Biodiesel can cause deviations in
temperatures and functionality of the DPF burner
and may cause fault codes or errors.
Biodiesel exhaust gas is aggressive to some
materials used in selective catalytic reduction
systems (SCR) and may require more frequent
cleaning, repairing or replacing of SCR parts.
Effects of biodiesel on cold weather operation
Biodiesel has a high viscosity at temperatures
below 0 ˚C (32 ˚F) and may cause problems starting
the engine. Use a fuel heater or park machines in a
heated building if possible.
Effects of biodiesel on engine performance
Biodiesel B100 has about 8% lower energy density
compared to regular diesel fuel. Blends equal or
lower than B20 have a small impact on engine
performance.
