1 Make your own Biodiesel Part 2

Anybody can make biodiesel. It's simple, you can make it in your kitchen area-- and it's BETTER than the petro-diesel fuel the huge oil business sell you. Your diesel motor will run much better and last longer on your home-made fuel, and it's much cleaner-- better for the environment and much better for health.

If you make it from utilized cooking oil it's not just cheap however you'll be recycling a problematic waste item. Most importantly is the GREAT feeling of freedom, self-reliance and empowerment it will give you. Here's how to do it-- whatever you require to know.

Straight grease fuel (SVO) systems can be a tidy, reliable and affordable choice. Unlike biodiesel, with SVO you need to modify the engine. The very best method is to fit a professional singletank SVO system with replacement injectors and glowplugs optimised for veg-oil, in addition to fuel heating.

With the German Elsbett single-tank SVO system for circumstances you can utilize petro-diesel, biodiesel or SVO, in any combination. Just launch and go, stop and change off, like any other car. Journey to Forever's Toyota TownAce van uses an Elsbett single-tank system. More

There are also two-tank SVO systems which pre-heat the oil to make it thinner. You have to start the engine on regular petroleum diesel or biodiesel in one tank and then switch to SVO in the other tank when the veg-oil is hot enough, and change back to petro- or biodiesel before you stop the engine, or you'll coke up the injectors.

More details on straight grease systems in my blog.

3. Biodiesel or SVO?

Biodiesel has some clear benefits over SVO: it works in any diesel, with no conversion or adjustments to the engine or the fuel system-- simply put it in and go. It likewise has much better cold-weather properties than SVO (however not as good as petro-diesel-- see Using biodiesel in winter). Unlike SVO,

it's backed by numerous long-term tests in lots of countries, consisting of millions of miles on the roadway.

Biodiesel is a clean, safe, ready-to-use, alternative fuel, whereas it's fair to say that many SVO systems are still speculative and need more advancement.

On the other hand, biodiesel can be more pricey, depending just how much you make, what you make it from and whether you're comparing it with brand-new oil or utilized oil (and depending on where you live). And unlike SVO, it needs to be processed initially.

But the big and quickly growing around the world band of homebrewers do not mind-- they make a supply each week or once a month and soon get utilized to it. Many have actually been doing it for many years.

Anyway you need to process SVO too, particularly WVO (waste grease, utilized, prepared), which numerous people with use since it's inexpensive or complimentary for the taking. With WVO food particles and impurities and water should be removed, and it most likely should be deacidified too. Biodieselers say, "If I'm going to have to do all that I might too make biodiesel rather." But SVO types belittle that-- it's much less processing than making biodiesel, they say. To each his own.
