When then time comes to have your truck smog tested, has anyone thought about using biodiesel for your fuel?

Biodiesel is a much cleaner burning fuel, and better for the engine and fuel system. I believe that when burning B100 or even B80 bio with all the deletes and mods the exhaust will be cleaner then a stock truck burning that dirty, filty diesel fuel.

Burning biodiesel also adds lubrication to your fuel system whereas the low sulfur fuels has taken all that lubrication out and is hard on the engine and fuel systems.

No modifications are necessory to use biodiesel, however; the one thing that you must be careful of is that if your truck has a lot of miles on it the biodiesel acting as a solvent will clean the built up gunk from the inside of your fuel tank, fuel lines, injectors, etc. Install additional fuel filters, change often and introduce the biodiesel gradually. Start with a 20% biodiesel 80% diesel and slowly increase that amount over a period of several months.

Currently I have a VW Golf TDI (the poor boy’s diesel) with about 160,000 miles.

My future vehicle will be a Laramie Ram Crew Cummins (a real diesel) 3500 SWB long bed with 3.73’s. The mod’s that I plan to do are: intake and exhaust upgrades, the deletes, performance chip, fueled primarily by biodiesel made by myself (I understand that home brew biodiesel when made properly is far superior in quality then the commercial made stuff) and cost about $1 to $1.25 a gal to make. I will install a second tank, fuel lines, and filter all heated so that I can use the biodiesel in the winter as well as summer, and I also plan to build and install a HHO generator.

I may be dreaming but with all the mods and using a HHO generator I hope to be able to get somewhere around 30 mpg.

I plan to get the truck this July, so I have until then to build the biodiesel processor, the HHO generator and plan exactly which mods to buy. Hopefully all the kits and parts for the 2010 will be ready by then.

 

Good question, I would like to know how it does on a smog test running bio.

 

It might pass the cleanliness test at the exhaust pipe, I don't know, but it won't pass the visual inspection if they look underneath or under the hood. The smog tests are not only about running clean, they are about having all the original equipment in place and operating as designed. We'll see how close they examine the trucks and whether or not someone can run a gutted DPF or cat, or a blocked off EGR. I doubt it. Too bad because it removes the chance for experimentation and even cleaner burning, or better mileage.

 

i have to fail a vehicle with the original equipment removed

 

is looking for the 2nd cat and dpf filter on your list of things to look for on a 2007 truck ?

 

The point of all that junk being on the trunk is to produce cleaner emissions, correct?

So if a person brings in a truck and the emissions are much cleaner than the requirement levels and he has all that junk removed, why will it matter that it has been removed?

If he still fails the so called check because of missing parts even if his emissions are cleaner then things need to be changed. The so called "laws" need to be challenged and changed or throw some of these self serving criminal politicians out of office and without their great retirement benefits so that we can make laws that will be in our "the people" best interest.

 

Unfortunately rules are rules... And yes, they need to be changed if there is proof otherwise. Do you really need 8 years of school to get a PHD and become a Dr., or can you just study on your own and take the test?

You aren't allowed to take the smog test unless you attend class and pass the visual test first.

 

Kblake,

Welcome to the real world. Again, it's not about cleaner, it's about having all the original equipment in place and working as designed. This has been the case in CA since 1965 and simply throwing the bums out has not worked so far. Nobody is going to win an election on the platform of promoting dirtier air and entrenched bureaucrats have to justify their jobs regardless of the impact on the public. The EPA is completely corrupt and broken. There are even overlapping agencies like the Bay Area Air Quality Control District that, with the stroke of a pen, caused a huge financial burden to boiler manufacturers and caused the cost of a home heater to go up by about $2,000. and the relaibility to go way down, causing further expense.

I think that if all smog rules were abandoned almost all trucks would be altered and many guys would be proudly smoking as much as possible. Not a good idea. But this current setup is over the top. The equipment reduces mileage, probably increases CO2, is expensive and causes a lot of reliability problems. Many of us will not buy a new truck because we don't want those problems.
