I had to type a report for english class, and chose to write about bio fuels and what not. what i came up with was: bio diesel is NOT helpful for fueling, it costs more to refine it than they make back, it's less powerfull, so more is used, and causes more maintenence to be done on cars and trucks.

gas prices are so high 1: because of the obvious but also 2: bio fuel advocates loby and some what demand that the price of dino fuels stay high to create a competitive market for bio fuels.

and ethonal? well that's just a joke. it's weak, makes cars run like... well, the crude term for a donkey, and pres. bush is mandating that we use more and more of it each year in stuff. and for those that don't know, ethonal is made primarily from corn, which means that the price of corn goes up, the prices at restaraunts go up (because they use a lot of corn based products in everything)... and the us is having a hard time meeting the mandated amount of ethonal right, and the amounts that is supposed to be used in fuels are supposed to go up.

oh yeah and i interviewed some one kind of high up @ a local franz bakery, they said they HATE that oregon is requireing them to use a 5% biodiesel blend, they lose money by using it.

 

Thanks guy's. I ordered a new pump for $36.00 on ebay what a deal..This one is way too loud to keep anyway..I'll check the regulator. Wheres the vac line,on the bottom?
Update: today sun after snowboarding I brought the van into the garage for an oil change. I sprayed the tank bolts with croil and looked at the rear brakes. I had to rip the rear drums off to get the adjusters out to free them up. Now the brakes feel like new..I even got the bleeders free and flushed the fluid. Lotsa anti sieze on everything..by the way the van took us to the mountain to do some shredding and brought us back home..Code 1443 evap I think keeps comming up so I need to look it up...

probably a vacuum line fell off or broke on the fuel vapor cannister under the air cleaner on the front frame.
the vac. line on the 4L is just long enough to reach. any work on top of engine often pulls it off or breaks it from ozone damage.

dcrb,
great on the English paper on bio fuel. talk to any of the truckers, they'll tell you horror stories about the bio diesel and the new ULSD
less mileage and kills engines

 

What you said about bio diesel is not correct. Other biofuels may require refining, but vegetable oils can be used in a diesel engine without any treatment other than filtering. It does produce slightly less power, but the difference is insignificant. If the glycerine is removed through treatment, then biodiesel is more powerful than fossil diesel (the fuel economy is still lower however, since a lot of oxygen is locked up in the fuel, reducing its density). Biodiesel is a safe fuel so long as it is derived from a safe source.

I have found that many of the injector failures reported were not due so much to problems with the fuels, but rather due to problems with the injectors themselves. I know a lot of truckers, and while many of them will tell me these horror stories, one thing I note is that none of them have ever had these terrible things happen to either them or anyone they actually knew. I am aware that low sulphur fuels can cause serious problems however.

The same cannot be said for ethanol. While ethanol is a great concept, it is a terrible fuel in the real world. And what makes it worse is the sources that farmers and the government are using. Corn is not a good source for the ingredients to make ethanol. It has a rather low density per acre, so it consumes large quantities of land. It also requires a lot of water and fertilizer. And then because it is a low density source, it requires a lot of processing and a lot of waste. There are much better sources, that require less water, less land and less waste in the processing. But of course they won't use the better alternatives because that would actually make sense, and would be less profitable for the guys at the top.

I ordered the vac sensor the valve worked fine and vacuum was fine..ordered the sheet metal today...

Something that many people forget is that one of the components that go into making biodiesel is...alcohol, either ethanol or methanol. So there's another marketing motivation for biodiesel; the corn growers just love it.

 

What they don't tell you is you do not need to treat the oils at all. A diesel engine will run just fine on straight untreated cooking oil. You don't need to treat it with either ethanol or methanol. Just filter it and run it right through. Of course, straight cooking oil is no good in cold weather, the refining process stabilizes it.

There is also a type of catalyzed biodiesel that is awesome. If does not have the glycerin removed, it instead runs through a specialized process ( a very cheap and fast process) which uses very small quantities of methanol. Inside the machine it converts the oil and the methanol into an enzyme that burns under heat and pressure. I worked with a guy who helped develop it. It was amazing how much power it produced. When they ran the trucks on it, the economy increased over the baseline by 12%, and the pyro temeratures dropped while the head temperatures increased (more combustion inside the engine). The vehicle was also noticably more responsive. The problem the company is having is zoning. They want to build a facility in either Northern Utah, Southern Idaho, or Western Nevada, but the zoning boards won't approve the plans. They consider the facility to be an industrial facility that deals with dangerous and toxic chemicals and won't approve the zoning. From a standpoint of the actual ingredients, the process is not really any different than a low level industry such as say, food processing.

Not to rattle the conspiracy theories, but there are people with a lot of money who through tools such as the media to attempt to sway public opinion. They also use idiots like our current president to demonstrate how impractical the current methods of biofuels really are, but in a way that they try to make all biofuels look bad. By doing this they can either keep us bound to the current energy sources, or control the alternative sources. While most of the biofuels are riddled with problems, biodiesel is not one of them. They try to tell you that you need to process and refine the stuff. If the oils are properly filtered, they don't need to be treated. The engine will run on unmodified cooking oil. Why don't they tell you that up front? Becaus ethats too easy. But if you look back at the invention of the diesel engine, it was intended to burn low grade inexpensive fuels. In South America, people have been using peanut oil to run their diesel cars for years. Just straight peanut oil, no additives.

 

If we can burn more biodiesel, it would go a long way towards removing our reliance on petroleum. But we will have to develop better ways to process biomass into diesel, as a gallon of cooking oil is still far more expensive than a gallon of diesel #2. Although, that may change soon.

 

i personaly laugh at how companies, such as trimet, go around advritising that they are helping the environment, while their buses and personal transports drive around belching black and blue smoke...

but what i said is only information i found on ebsco.... so it is what it is. definately an interesting topic tho. and as far as i'm concerned, the only thing that keeps me from wanting a diesel powered anything is the smell. it makes me gag....

 

Thats why you keep the catalytic converter on the diesel vehicles. They don't produce much or a smell at all when people leave them in the stock form. Its all these performance enthusiasts who cut them out and install straight piped turbo back systems that blow all the smoke. I'm really interested in the 2010 Accord Diesel.

 

Gentlemen,

The problem with all the bio-whatever fuels is quantity. All these fuels are good and should be used but the enormous quantities of fuels used are, well, enormous. We consume 20 million 42 gallon barrels per DAY of petroleum each day. A plant making 900 barrels of fuel from turkey guts in Arkansas is just not significant.

We must search for and drill for more petroleum wherever it can be found.

Come on guy's I thought I would start a thread with my experiences redoing this 96. I don't usually object to a few posts but!!!



Dick

 

Agreed, if we wish to discuss biofuels further, we should start a new post.

 

Ok so did everyone know that if you mash the antenna you can just pop out the 3 screws and pull the cable out and put in a new top without replacing the cable. Boy am I glad...Got the ebrake working. I'm off to the dealer to get the purge flow sensor.

Dick

 

The ebrake issue of always getting too tight can be fixed with 2 springs number 63 at the hardware store. You attach under the van at the cable tee to the frame so that the cable gets pulled back quick. You have to shorten the springs. I'll get a pic up soon. The purge flow sensor did the trick on that cel now I have a p0402 egr gotta get going on that. I have the gas tank down and pump replaced, the straps are toast so some are comming ups tom morn from NH. I was lucky to get them. Does anyone have a line on some. Dealer say's no. I also replaced the brake line behind the tank and did any rust work that needed to be done.
I hope to see the fuel pressure come up to normal tomorrow morn.
Things left to fix,,Ac,cruise control. Rockers ,,Oh sheetmetal came in Raybuck is great..
