Biodiesel Compatibility Factors

Biodiesel is an alternative fuel that contains no petroleum, foul smelling aroma, used in providing energy for engines.  The chemical process involved in producing biodiesel has to conform with ASTM D6751 before it can be distributed for use as a fuel.  The standard covers the blending of the raw material with some amounts of petroleum diesel.  Commercially, the percentage of biodiesel used is 20% combined to 80% diesel fuel before it can be used as consumer good.  It is known as B20. 

In pure form, it has the capacity to melt other alkyd solids from where it has direct contact.  In case of an engine, it is considered to be self-cleaning because of the dissolving property.  Some remnants of solids not dissolved inside the engine are trapped in the filters, which will require cleaning.  Without blending the biodiesel, its pure form can ruin some material properties of the valves of machineries. 

In case of storing pure biodiesel, there are certain materials that are required for this purpose.  Other materials have been tested to find out if they are vulnerable to reactions when used with biodiesel.  It has been tested that metals increase its oxidation faster, causing gel coagulations during storage. 

The only acceptable alloys that could be used for its direct keeping are stainless, aluminum and carbon steel.  Brass, copper, zinc, bronze and lead should be avoided as pipes and fittings.  For plastic materials, there is a very minor reaction when using viton and nylon, especially for lesser percentage of biodiesel dilution. The most acceptable storages are fiberglass, fluorinated polyetheline, and Teflon.

While older engines are not biodiesel compliant, the rest of the manufactured ones since 1994 are already compatible with biodiesel.  The details to be checked from time to time are the sealants and rubber gaskets joining some components together.  This factor can be easily ruled out by the manufacturer of the engine, as part of maintenance routine.

It may seem to appear complicated when dealing with biodiesel compatibility, but what matters is the benefit it can do to the environment in general when it comes to its use.  A series of studies has shown that its emission is not harmful to humans.

Its acceptance will pave the way to a better change, which is something of value to the economy in general.  When these fuels power most of the giant equipment used in industry, the percentage of contaminants will be lessened if biodiesel is the primary fuel to be used.

Actually, the safety margins on material compatibility are just ideal suppositions on how biodiesel can affect the functioning of an engine.  Currently, use of biodiesel will not revoke warranties.  Diluted as specified, most engines will do well on its prolonged use.

The good thing about technology is the speedy updates of consumer goods.  Whenever there are new propositions or innovations, each competing company will always comply and adapt to the change in demand.  In this case biodiesel is gaining popularity faster than expected and so engines have been upgraded to conform to its elements.

The invention is in itself harmless to the engine in general, that is why manufacturers are not threatened by its application with respect to the warranty they give.  It is expected that biodiesel will cause a great deal of changes for the better in many aspects of life.
