I do, I'm all for reducing the amount of emissions.

(See what happens when you do Geography at school!)

How do you go about making Bio-Diesel? It doesn't require large amounts of electricity like making Hydrogen does, does it?

EDIT: For anyone else who is interested in Bio-Diesel check out this place:

Biodiesel is not hard to make if you know what you are doing and have the right equipment...

http://www.freewebs.com/phongus/ <--- that's my website that I made for my uni research 2 years ago or something.

If you know your chemistry then you should be alright in making it. I was planning on trying it out in small batches...but i don't have a diesel engine.

phong =P~

yeah...still leaves you with needing a diesel engine which im pretty sure is difficult to make from the ford sohc i6

They have been dropping Chevy v8 Diesels into holdens and 4wd vehicles for a while now. Massive torque, good fuel consumption, but!!!!

Heavy weight (25% or more), expensive to service/rebuild (fuel pump $1200 plus).

The turbo I6 gives more torque than most can handle or need.

Fuel consumption needs to be balanced against cost of purchase ($8000 Plus) /installation/servicing etc. This is a very user defined balance.

Weight is not just the engine. Fit heavier engine and you could need different (as in expensive) springs, shockies, brakes, drive line (extra torque), etc.

I'm not knocking diesels but you really need to think it through. The newer diesels with pnuematic valve actuation (Sturman Industries), variable turbo housing technologies, particulate filters, lighter weight blocks and electronic control look very promising ,,,,,,and expensive.

Think of it this way, how many miles (sorry klms) would you have to cover to start to reclaim your investment after servicing costs are added in.

Diesels are more efficient due to compression ratio. Run 12.5:1 with water injection, 2lb boost and other mods and the difference will be reduced.

heheh making your own bio fuel is easy. just go to a fish and chip shop ask if you can have their used vegetable oil in the deep fryer catch pans, take it home, filter all the gunk out of it, and presto, free fuel for your diesel.

Any diesel engine will run off pure vegetable oil. tho i guess it isnt very practicle unless you have access to a lot of used vegetable oil for free and the patience to clean it.

EDIT: bah i guess veg oil isnt really a bio fuel, mor of a petro diesel. but meh.

yes diesels use glow plugs to ignite the fuel as appossed to spark plugs as diesel requires a higher temp to ignite. they also use a lower comp ratio.

just droped some fuel out of a HZJ75 and it was bio diesel and f**k MAN it smelt like Paint thinnners no joke on the smell so me thinks Bio Diesal not good.

prolly as said before diesal need stronger blocks and head but i wonder if you got a cast iron head of a early falcon and put it on the xf block with nah that wouldn't work it comes done to he injection of the diesal???

well.... this is a funny 1... Shave alot off your head. Stock cam. Screw in glow plugs where ur spark plugs go... Remove your butterfly on the intake...fit the diesel injectors and pump and it may work lol... Diesel fuel has a RON rating of like 45 so the hi-comp doesnt mean to much for block strength.. Also other s**t i didnt not say of course lol just a stab.

Biodiesel shouldn't smell like paint thinner as far as I know...if it does, i think there must be something else in the engine...Should smell like whatever it was made out of.

phong =P~

diesels comp ratios should be between 14 and 25 :1

they dont use glow plugs to ignite the fuel. the diesel is injected into the cylinder in a fine mist at high compression and spontainiusly combusts

The glow plugs create a hot spot for the fuel to start ignition when cylinder is cold, sort of like carbon build up produces a second flame front on a petrol engine (detonation/pinging).

Once warmed up they are not required.

When you see aerostart (ether) being used for starting a diesel engine it is not because of the fuel, it is because that engine has lost compression and has difficulty achieving the ignition temp of diesel,even with glow plugs.. Ether ignites at lower temps.

Please help me with my confusion.
Carbon is a by-product of the combustion process. That being so. Why would there be carbon deposits inside the fuel line, lift pump, fuel filter(s), injector pump, injector lines or injector?
Isn't that solely reserved to the combustion chamber, pre-combustion chamber (if so designed) and
associated plumbing? If I am correct what possible harm could bio-diesel do to the fuel delivery system?

A few questions

Are you looking at fitting a diesel enine to your car?
or using your petrol engine as a diesel? (that probably won't work lol)

I've always wanted to see if a toyota/nissan i6 diesel would fit in the engine bay of the E series, probably would with a bit of modding.

Its mainly older diesels that use glow plugs now, I know with my old SD33 she won't even think of firing up without a 20-30 second glow in the morning! And they only come on when starting, once the engine is running they switch off, diesels use very high compression to ignite the fuel.

Newer engines are usualy direct injection and have a small combustion chamber in the top of the pistion and instead of seperate glow plugs they have a heater in the in the intake manifold to heat the air as it enters the bore, they will usualy fire up as soon as you hit the key!

As for Biodiesel (well fish and chip oil) Alot of people just filter the oil very well then modify the car to run on the oil.
First the car is started on normal diesel and begins to heat the oil up so it is the right viscosity to be run through the injectors, then its switched over to the oil when up to temp, then when its about to be shut down it goes back to diesel to clean out the injector pump/lines ect.

I've also heard of people running water injection to stop the carbon build up from the chip oil

This company reckons thay can convert any engine im looking into it for my landcruiser
