Worldwide Fuel Charter (WWFC) is an international specification for diesel fuel published by all major automobile and engine manufacturers worldwide.  The values shown are for category 3 (or Euro 3 diesel fuel) intended for markets with advance requirement for emission control.\

Flash Point – the temperature in which minute quantity of vapor begins to form and begins to flash when an open flame is passed on to it.  It is basically a measure of storage safety.  Coco biodiesel has a flash point of 107 o C while commercial diesel has a flash point of just about 55oC. Therefore, coco biodiesel is twice safer on storage than commercial diesel.

Sulfated Ash is an element that wears out the fuel injection system.  As shown, the value of coco biodiesel of 0.002 is 10 times better than the 0.02 specifications in EN and ASTM standard.

Sulfur Content is a major air pollutant. It produces acidity in the engine (i.e. sulfuric acid) that can eventually wear out the engine. Environmentally, it causes acid rain and respiratory health problem.  Coco biodiesel only has trace element of sulfur at 3 ppm compared to 10ppm and 500 ppm in EN and ASTM standards as well as the 30 ppm standard of WWFC.

Cetane Number is a measure of ignition delay (or time gap) from fuel injection to combustion.  Low cetane means longer time gap manifested by slow acceleration response.  High cetane means shorter time gap manifested by quick acceleration response and better cold startability.  Coco biodiesel has cetane number of 70 compared to 50 of diesel itself. It surpasses the WWFC standard of 55 min.

Oxidation Stability. The biodiesel standard under EN 14214 is 6h (minimum) while commercial fossil diesel is 16h (minimum). Coco biodiesel has 18h and therefore surpasses diesel on the matter of oxidation stability. It is less prone to oxidation and bacterial growth than unadditized diesel itself.

Free Glycerine/ Total Glycerine.  High percentage of glycerine will produce soap formation, sludge, and injector nozzle caulking in diesel engine.  Free glycerine of highly process CME is only 0.005 versus 0.02 of EN and ASTM.

Very Low CFPP ( COLD FILTER PLUGGING POINT ) –8 C. The temperature in which the liquid begins to crystallize, the start of  solidification. Coco biodiesel has a cloud point of –5 o C, which indicates a better cold flow property specially when used in colder climates than Manila. The typical CFPP test results of coco biodiesel is minus 10 C but BioEnergy 8 Corporation guarantees at minus 8  C to be conservative. It is important to note that coco biodiesel can achieve this CFPP of minus 8 C without any additive and without sacrificing oxidation stability. Other vegetable oil derived biodiesel may also achieve very low CFPP but have much lower oxidation stability.

Very high in Solvency and Detergency.  This unique characteristic of cocobiodiesel which has a doable action benefit:
a. Dissolving carbon impurities and sediments on the fuel blend to enable efficient combustion.
b. It cleans the engine as it disperses the dissolve carbon deposits and sediments which are then all converted to energy upon ignition

Viscocity is the same as petro diesel. Viscocity values outside the range specified by the engine manufacturers will affect fuel delivery, operation of advance units and governor mechanisms. Higher viscosity can result to poor combustion accompanied by power loss and a risk of pump failure at start up  in cold conditions.

Reduced SOX, NOX, CO2 and PM emissions. Because cocobiodiesel came from vegetable origin, they don’t have any sulfur ( No SOX ), it has lower temperature properties during combustion hence, lower NOX and 80 % lower in CO2  emissions compared to petrodiesel due to its complete combustion, particulate matter in the emission ( exhaust ) is negligible.

Acid Number is a value that measure the fuels corrosiveness on metal component especially the fuel injection system. CME has an acid value of only 0.17 which substantially surpasses EN specification of 0.50 maximum and ASTM specification of 0.80 maximum.

CFPP ( Cold Filter Plugging Point ). Because of the way diesel fuel jells, a new system for rating winter diesel is being developed. The pour points are not realistic because the test does not take into account that fuel has to pass through a fuel filter. Diesel fuel can have a very high level of jelling and still pass the pour point test. A test called “ Cold Flow Plugging Point “ or CFPP measures the fuel’s ability to flow through a fuel filter. Cold flow performance to pass the CFPP test will be 2C degrees maximum above the ASTM D-975 tenth percentile numbers.
