Company Description

Make your own Biodiesel Part 1

There are at least 3 ways to run a diesel engine on biofuel utilizing veggie oils, animal fats or both. All three are utilized with both fresh and secondhand oils.

1. Use the oil just as it is– usually called SVO fuel (straight grease);

2. Mix it with kerosene (paraffin) or petroleum diesel fuel, or with biodiesel, or blend it with a solvent, or with fuel;

3. Convert it to biodiesel.

The very first two methods sound most convenient, however, as so frequently in life, it’s not rather that easy.

1. Mixing it

Vegetable oil is much more thick (thicker) than either petro-diesel or biodiesel. The function of blending it or mixing it with other fuels is to reduce the viscosity to make it thinner so that it flows more freely through the fuel system into the combustion chamber.

If you’re blending veg-oil with petroleum diesel or kerosene (very same as # 1 diesel) you’re still utilizing fossilfuel– cleaner than a lot of, but still unclean enough, many would state. Still, for each gallon of

veggie oil you use, that’s one gallon of fossil-fuel saved, and that much less climate-changing carbon in the atmosphere.

People utilize numerous mixes, varying from 10% vegetable oil and 90% petro-diesel to 90% grease and 10% petro-diesel. Some individuals just use it that way, begin up and go, without pre-heating it (that makes veg-oil much thinner), or even use pure veggie oil without pre-heating it, which would make it much thinner.

You might get away with it with an older Mercedes 5-cylinder IDI diesel, which is a really hard and tolerant motor– it won’t like it but you most likely will not eliminate it. Otherwise, it’s not wise.

To do it effectively you’ll require what amounts to an SVO system with fuel pre-heating anyway, ideally using pure petro-diesel or biodiesel for starts and stops. (See next.) In which case there’s no need for the blends.

Blends with different solvents and/or with unleaded gasoline are “speculative at finest”, little or absolutely nothing is understood about their impacts on the combustion qualities of the fuel or their long-term effects on the engine.

Higher viscosity is not the only issue with utilizing grease as fuel. Veg-oil has various chemical homes and combustion characteristics from the petroleum diesel fuel for which diesel engines and their fuel systems are created.

Diesel motor are modern devices with really exact fuel requirements, especially the more contemporary, diesels (see The TDI-SVO debate).

They’re tough but they’ll just take so much abuse. There’s no warranty of it, but using a mix of approximately 20% veg-oil of excellent quality is stated to be safe enough for older diesels, specifically in summer season.

Otherwise using veg-oil fuel needs either a professional SVO solution or biodiesel. Mixes and blends are usually a bad compromise. But blends do have an advantage in cold weather condition.

Just like biodiesel, some kerosene or winterised petro-diesel fuel blended with straight grease reduces the temperature at which it begins to gel. (See Using biodiesel in winter) More about fuel mixing and blends.
