Natural Gas

[BrSurfer]

As you wish, I´ll try give you more information about Natural Gas convertion.

My Pathy(95 v6 SE) already runs using this technology since 2002. So far I got no trouble and even make me save money.

 

First of all, I´ll give you a list of what come with a conversion kit.

 

a) One(or more) NG storage cylinder. Each cylinder suports pressure of +-700 psi, but they are only loaded with 200psi (security reasons).

The capacity depends of the size of them and local temperature.

One cylinder, that occupies half of a 95 Pathy´s trunk, must storage +- 25 m3 of NG at 200psi.

25m3 of NG can drive you 120 miles in city traffic or 175 miles on road. Important thing, each m3 of NG cost 50% of an gasoline liter.

The gas cylinders are equipped with safety valves which are opened when the pressure grows. These are very strong bullet proved devices.

Some pictures of Cylinder´s installation.

 

That Pathy (not mine) have huge storage, must be 55m3(two cylinders) or more, but no more trunk

These are two JGC with diferent configuration.

Injector Simulator. This is a litle eletronic device that full yours ECM saying that injectors are working when they are not.

When you switch to NG yours injectors are turn off. So, this device "tell" your car´s control unit that everything it´s ok.

 

c) Pressure controler. It´s a mechanical device that serves to regulate the pressure of the gas.

Control gas flow to engine and manage to increase gas temperature.

d) Timing Adjuster. The engine, when runing NG, must work in advance. So, this eletronic device manage

the trick of adjust timing when you switch fuels.

 

e) Dissipator - Conect the lower gas pressure lines to the intake. Drop the NG to the engine.

 

f) Switcher. Give´s you fuel status in cylinder and let you switch from one fuel to another.

That thing under the wheel in this picture:

http://www.anchietagas.com.br/fotos/jeep/g...rokee_chave.jpg

 

g) Lines. high pressure Gas lines(pressure controler to cylinder) and low pressure gas lines(pressure controler to engine intake).

 

Hmmm, I think these is almost everything...

 

More information:

 

Well, when runing you can always switch from one fuel to another.

The NG usually makes you car loose about 10% of power, so I use gasoline when a needed (extra power ).

This power loose exist because the engine is not originaly made to run with NG. But, if I´m not mistaked, you ´ll have a gain of torque with NG.

However, a NG based engine CAN be much more powerful that a gasoline engine.

It´s possibe because NG octane it´s much higher than gasoline, and so, the engine could run a hight compression tax without problem.

Here, in Brazil, we have competition`s cars that run only NG.

 

 

Technical effect

The oil is not rarefied or polluted with combustion products, and as a result,

the life time of oil increases 1,5-2 times, the oil operating consumption decreases by 15-20%.

The engine working life time rises on average by 35%.

 

Ecological effect

 

When the engine is operated on natural gas, the emissions of carbon oxide CO are reduced by 4-5 times, of nitric oxide CxHx.

 

That´s all folks!!

I like the idea, but I don't think I'd like the tanks in the back of the truck. Where can you get'em refilled? I have NG running to my house. Is there anything I could buy so I could refill my own tank??? What's with the color of the tanks??? Is that a law or something?

 

PS: Thanks for posting this, very good alternative to gas.

[BrSurfer]

Yeah, I know, the tanks in the trunk sucks. :sniff:

About refilling, I just go to the gas station.

Exist a net of stations that are able to distribute NG here.

Of course, all these sites must be certified to do it.

You can´t do it by yourself because the compressor and all devices are too expensive.

Moreover you must have oficial permission(security and ambiental reasons).

 

Color: I think it´s a convection or something.

 

here some picture of a GNV race pickup.

[Cuong Nguyen]

That's fascinating. I don't know many natural gas places here in my area where I could refill if it need be.

[Harbinger]

There are stations even in the states that offer NG. When I was first looking for a vehicle (Age 15) I found a 84 chevy .5 ton that had been converted. Was to expensive for the time though.

 

I wouldn't mind giving up some room in the back for a tank, as I think the benefits of a multi-fuel engine would outweigh the space issues. I plan on a plywood cover for the back anyway :-)

 

What is the cost of the parts and installation?

[BrSurfer]

Here, in Brazil, a conversion costs U$ 1400(all included).

Mostly of the parts came from Italy I think.

But ,my rig was already converted when I bought, so I didn´t have to spend that extra.

[k9sar]

if only my pathy would run on the natural gas that I produce, I'd be in great shape.

[88pathoffroad]

Ha, ha, ha, k9sar.

 

Nice! I bet that's helpful when gas prices are so high.

 

Now let's see a diesel Pathy with a conversion kit to run on fryer grease.

[DJ Dank]

Well what about the flux capacitor Doc?

[n0cturne74]

RUN FOR IT MARRRTTTTYYYYY!!!! LOL

 

A NG conversion is the way to go. California is pushing that route and hopefully other states will also. There needs to be a lot more stations to refuel or an affordable method for self refueling.

[revgolem]

Most of the truck rental places (like U-Haul) around here have the tanks to re-fuel. There's probobly a lot more out there than we notice.

[red-finder]

88 I saw a show on the Trucks TV show that told you exactly how to make diesel out of old cooking grease. The whole set up to make it cost $850 then all you had to do was get the grease and some lye. They said the exhaust smelled like french fries! After the intial investment you could make a gallon of diesel for about 70 cents.

[dnodog]

man i wish i could do that with my old diesel pathy.... that would save me about 5000 bucks a year... mmmm

[DJ Dank]

Yeah it'd be nice to have for environmental and financial purposes in the longrun, but to give up all your cargo space for it...I dunno...

[dnodog]

well i meant the diesel from cooking grease, i wont have to give up my cargo space{ at least i don't think so}

[red-finder]

dnodog here is the website for the equipment.

Freedom Fuel America

They say it is perfectly safe and actually lubricates the diesel engines better than regular diesel. I was very interested because some day I want an F250 diesel. I will also keep the Pathy of course!

Just a quick word of advice... Stay as far away from PHORD as you can... They're making @!*%tier and @!*%tier vehicals every day all day long... They are however good for impressing co-workers and about 20,000 miles.

This was showed on DIRTY JOBS last week....pretty interesting stuff.This is good for the environment but money wise I dont think its any cheaper than gas...think about all the driving you have to do to collect all those used grease then the processing time ......For the environment I would use it

PS: Thanks for posting this, very good alternative to gas.

The US government dosn't want you to have CNG tanks in your truck ether, CNG tanks run between 3000 and 3400 lbs how they are done here in the us and you have to have a special licance to have a tank with over 2800 lbs in a automobile. If it was legal to run CNG here I would already have my dodge converted, as my work has all the parts to do it. We build LPG CNG and gas engines, also NG engines. So people know NG and CNG are different in that CNG is compressed witch is what you have to run in a vehicles because you can not have a line running from the NG line coming from the ground to it. Well at least if you want to go anywhere. The closest we are allowed to run here in the states is propane. The exception to this is the Honda car with a CNG tank but they run very low CNG pressure and because of such have a very limited range and are only sold in California. And are very hard to fill up as most stations do not carry it, But if you have a NG line at your house you can get something called a fueler, Witch compressed the NG coming from the line at your home, but it uses allot of power and cost a couple of grand.

[94extreme]

there are a few pathys in the southern states running on LPG. i think those guys are/were on N4W, iirc.

[BrSurfer]

A friend who lives in UK sent me a email saying he was about to buy a Defender land rover and then convert it to run NG. I'm not aware that this could be done on a diesel engine...Anyone knows anything about it?

Ive been running my Terrano/Pathy TD 2.7 on a mix of LPG n Diesel now for the past 2 years n it goes real good it has a lot more grunt than the std TD2.7.

THE ONE THING WHEN useing LPG is adjust it so it just starts to ping then back it off as the pinging is telling you you are giveing it way to much LPG.

( this is a stop start situation of trial and error)

The other big thing is have it set up so that when ideling the LPG gets turned off other wise it will idle real rough

Here is a mob in Oz who have perfected the Diesel Gas system, costs around 3800 to get it set up, but here in Perth you can get 3k back in govt subsidies
