Running On Vegetable Oil

In the field of alternatives to regular diesel, there are two options. Both can be very cheap, and both are renewable fuels with environmental benefits compared to diesel. The word "biodiesel" has become aware that some service stations are beginning to offer biodiesel blends, but unrefined, pure vegetable oil can also be used as fuel in a diesel engine. This article summarizes the key points of biodiesel from SVO debate.

What is the difference between biodiesel and SVO?

Rudolph Diesel designed his first engine to run on peanut oil, which, before there was something like "diesel" engine was made was already compatible with fuel oil unrefined vegetable. The oil is "pure vegetable, given the acronym SVO, is less than the same vegetable oil used for cooking. A variety of vegetable oil is okay, even used cooking oil (provided it has been filtered).

Biodiesel, however, is an ester chemical derivatives of vegetable oil, but refined to a lower viscosity.

What are the functional differences between biodiesel and SVO?

One obvious difference between the fuels you a notice if you held a container on each side by side is that SVO is much more viscous than either biodiesel or petroleum-derived diesel (for example, it does not flow as easily). The functional difference of all is that while biodiesel might work well in an unmodified diesel engine, changes should be made to a diesel engine to enable it to vegetable oil effectively and safely on the long term. It is largely a consequence of the higher viscosity of vegetable oil, although vegetable oil also has properties different from combustion of diesel fuel.

Problems arise from viscosity (thickness) of HBV in the fuel injection system of the engine, where the viscous substance wear much more than the relatively smooth diesel / biodiesel. Over time, the fuel injectors can become choked with deposits for the use of vegetable oil. Another problem arises in cold weather, where vegetable oil are still several times more viscous, and become virtually impossible to power the engine.

Engine modification

The most significant change made to a diesel engine to enable it to accept the vegetable oil is the addition of an oil heater. Not only does this solve the problems of engine starting in cold weather, it will also make the oil more flexible and reduce the stress on the injection system by lowering the oil viscosity. Other modifications may include adding a second tank of SVO to allow dual-energy use, or the use of specially designed fuel injectors with injection pressures higher.

fuel mixtures

Although biodiesel is widely and easily mixed with petroleum-derived diesel and SVO many fans does a mixture of other additives in SL to reduce its viscosity, it is wiser to biodiesel blends instead of the vegetable oil. The reason is that beyond the difference in viscosity which is the most obvious difference between fuels, vegetable oil also has different combustion characteristics than either biodiesel or regular diesel. Biodiesel, however, is much more miscible because its combustion characteristics are much more similar to petroleum diesel.

Usability

The fact that the SVO can be introduced into a modified engine properly without having to go through a chemical conversion is the main factor in his favor. Although the conversion process is simple and there is not much that is very complicated on the use of a biodiesel processor at home, the fact that chemicals are needed and the time necessary to operate the processor performs simple SVO implement Ove.
