1HD-FTE, Biodiesel and 3rd world fuel.

[Guest]

Hi,
This is primarily aimed at our resident diesel guru Craig (morning!);-)
I'm very loosely toying with 'upgrading' to a 100 series, but would
like to know a bit more about how the fuel injection system on the 1HD
-FTE works with specific reference to how it is likely to behave
running 100% Diodiesel as well as how it is likely to behave with
poorer quality fuel that you are likely to encounter in places like
North Africa.
Currently I run my 80 on 100% biodiesel and it seems to run fine. I
appear to have a little more power than I do with normal pump fuel but
tieing in with that I tend to get slightly poorer consumption.
I have heard stories about some electronically controlled injection
systems being quite fussy with biodiesel and just shutting down.
I guess they could do the same with poorer quality fuels.
Craig, do you have any experience/views on the subject?

Hi Julian,
I have never run a 100 series on it but I suspect the injection system
is dumb enough that you won't upset it. As long is the biodiesel is
properly made (i.e. not contaminated with methanol or caustic soda) I
can't see any problems. Biodiesel has naturally high lubricity
characteristics. Some cheap insurance is a injector additive and or
cetane booster.
If you suspect you will be picking up poor fuel then upgrading to
something like a Racor 900FG filter with a 300W heater in it should keep
contaminants in check. The nature of the turbine series Racor tends to
shed a lot of muck before it gets to the element and the bowls water
capacity is pretty huge. I have not tried it but you could possibly
still run a Walbro pusher to help the injection pump as well. I would
not risk suspect fuel in a Toyota avensis with the piezo-electric
injectors I suspect that might be pushing your luck. Since the calorific
value of biodiesl is lower that is why you use more and I have alway's
noticed I need to richen up for it to make good power. From memory your
truck is on the thirsty side so it may already be set quite rich. So
that the bio diesel still runs at an acceptable mixture.
You would probably want to beef up the front suspension but once
strengthened you will find they ride a lot better on rough roads at speed.
Cheers,
Craig.

Hi Craig
what do you mean by that 'beef up'?
cheers

Hi Craig,
I do occasionally get some powdery sludge in the Biodiesel, but nothing
major, but appreciate the benefits of the Racor filters, always reminds
me of the filters on the tractors and combines on the farm - it's nice
to actually see what is going through.
I certainly haven't had any major issue with the cold. OK, I don't
live in the arctic, but do live relatively high up and where the car is
parked it is quite exposed, but so far no problems, so not sure if a
heater would be necessary - this is 100% Biodiesel as opposed to veg
oil.
With biodiesel my main concern is the ECUs being too clever by half,
not recognising the fuel and shutting down - I have heard this has
happened with some of the more sophisticated modern diesels.
As for the 3rd world fuel, mainly concerned with fuel in N. Africa, but
guess that a Racor (or two) will fix the problem.
I would most likely go with the Walbro 'upgrade' as a matter of course.
I guess the main thing I need to find out is what actual sensors the
1HD-FTE uses. I'm guessing that it will have an air mass meter and an
exhaust gas sensor - do you know what others.
Someone pointed out elsewhere that there may be a 'safe mode' or 'limp
home mode' if the engine gets nervous of the fuel, I guess if one
exists with the 1HD-FTE I would need the ability to reset this,
presumably via an OBD II connector.

Hi Lubo,
I mean remove the front lower control arms and reinforce them where they
tend to crack and break near the torsion bar mount, fit better quality
shocks. As far as I know nothing exists to increase wheel travel for the
100 like the hiluxes as longer suspension travel can limit the damage of
heavy impacts. I used to have a hliux that I upgraded (by changing ball
joints, upper control arms, shock's and shock mounts) from 5.5" front
and 7" rear travel to 10" travel front and rear and it rode much better
and very rarely hit the bump stops.
Cheers,
Craig.

Hi Julian,
A 2 micron filter should keep dirt out of the injection pump.
A 900FG runs a 12V 300W heater as an option it can't hurt as biodiesel
is more viscous than dinosaur diesel fuel (I would not dream of running
straight vegie oil) the heater is temp controlled so once the fuel is
upto temp the heater turns it self off (the fuel run in on a test bed
is fed in under pressure at 40-45C). The cloud point temp of biodiesel
is quite high. If the injection pump can't suck it up when cold and it
cavitates the pump will not last very long doing that.
No air mass sensor, a inlet air temp sensor and a map sensor determine
air flow, no exhaust gas feed back, the other sensors are throttle
position with drive by wire throttle, fuel temp I suspect, water temp,
oil pressure, oil pressure?, crank angle sensor. It is a open loop
injection system you can add a D-tronic piggy back computer to make it
more responsive to the throttle as from toy the off boost fueling is et
very conservative to the point that some manual trucks are difficult to
pull away in with a heavy trailer because the is so little off idle
torque that the poor clutch gets slipped to death.
Injection pump calibration seems to vary a lot with some driving nicely
and others not. If adding a D-Tronic it is often worth removing the
injection pump and reacalibrating it first as if it is too far towards
the poor performance end of the factory tolerances the D-Tronic will
make little difference and still be a very lazy truck.
The factory turbo is pretty delicate Maartens sport turbo can be used as
a uprade for power and durability, Facory muffler creats close to 5 psi
of back pressure. I wish they had fitted a decent size intercooler.
Maarten has a bespoke piggy back computer that is meant to be amazing
for improved power/drivability and economy but I don't know much about it.
For pre-running type driving (i.e. travelling at reasonable speed at
poor quality roads) I prefer the independent front suspension due the
the reduced unsprung weight it can absorb impacts more easily rather
than transferring them straight into the truck. For crawling through
very rough terrain the live axle is hard to beat. For carrying two
people and a little gear this would be nice http://scorpioncars.com/
some of the side hilling photo's are amazing.

Hi Craig,
I'm trying to find references to the specs on this, but am just coming
across duff links - do you have any links with specs?

Hi Julian,
http://www.parker.com/RACOR/PRODUCTTABLES/TABLE-TURBINE.JPG
http://www.parker.com/ead/cm2.asp?cmid=9985&
<http://www.parker.com/ead/cm2.asp?cmid=9985&> you could try here but it
did not work for me. I have copy of their entire catalog as a massive
PDF if you want more deatils. Don't look at all the spin on versions and
go one of those would be pretty as yes they maybe but the elements can
be 4-10X as much as a turbine series filter element as on them you just
undo the tee hadndle lift the lid and drop in a new element. The 500FG
is adequate but the downside is the 900 elements are not much dearer and
will hold about 5-6x as much dirt.
Cheers,
Craig.

I am sure the 500 series is more than adequate. Of course, you could
do better than 2 micron but what's the point?

Thanks, I was looking for a UK supplier.
I see they have the 900FH on offer at =A3121.88 - looks a pretty good price.
