We convert diesel engines in the Philippines to run on pure
vegetable oil. Using vegetable oil as fuel results in tremendous advantages to
the environment particularly against global warming which has reachedalarming proportions.
advantages of using vegetable oil as fuel are:
Better for the Environment
Less Smoke Belching Apprehensions
Cheaper if Waste Cooking Oil is used
The environmental benefits of vegetable oil as fuel has been well documented and disseminated by the government and biodiesel groups. Due to the characteristics of vegetable oil as fuel, even a 1% blend with normal diesel already produces a marked decrease in Particulate Matter, Carbon and Carcinogens. Just think that since our method is almost 100% vegetable oil, then the benefits to the environment is 99 times faster and greater than the present Biodiesel blend.
On the other hand, Smoke Belching Apprehensions in pursuance of the Clean Air Act,has been on the rise due to field operations by government agencies. Their equipments measure only Opacity as a K value for diesel engines. Carbon residues and unburnt fuel are detected as dark smoke. Actual Tests in the Philippines using pure, waste vegetable oil in a Biodrive-equipped vehicle have shown more than 30% decline in actual Carbon Dioxide emission and a startlingly significant improvement in opacity. Recent Smoke Tests using a Bosch Smoke Meter showed 30% to 75% reduction in black smoke at different engine loads and rpm. In fact at some speeds, the smoke was colorless, similar to gas engines.
Aside from the above advantages, the use of pure vegetable oil as fuel can be cheaper if waste vegetable oil
is used. That’s right waste cooking oil.It is the same cooking oil
we use for frying in the house and finds its way polluting our sewers. It is
also thrown away by food processors in huge quantities. Actually this waste oil
is sold by the food manufacturer’s personnel to unscrupulous traders
who use it again for human consumption. This waste oil is unhygienic and
contains high metals, free fatty acids, molds, and the like beyond levels
considered safe for humans. This is wrong and must be corrected in our society.
Waste cooking oil, in our opinion, must only
be used to fuel our engines and not be allowed to go back to the food chain
whether directly or through animals fed with waste cooking oil added to their
At present day market conditions, the target savings on diesel cost average P15 per liter using our system. This savings figure varies.
Our conversion equipment allows us to use
vegetable cooking oil on normal diesel engines safely and without added wear on engine
parts. How we do this? First a little bit of history of the diesel engine. In
1892, inventor and engineerRudolf Diesel patented his invention of an
igniter-less engine characterized by higher compression ratio and ran on
ammonia vapor. It was a dismal failure on that fuel. Later on, he unveiled
innovations to it and made it run on peanut oil and was presented in a popular
International Paris industrial show in 1900. It was robust and also ran on
several other plant oils and a petroleum crude oil derivative of the gasoline
manufacturing process. This crude oil byproduct was later on called Diesel
Fuel. Petrol-derived diesel fuel became very popular as it was available in
large quantities and manufacturers could chemically mix and modify it to do
what they want such as lubrication of engine parts. The Diesel designed engine
has proven to be a tough, reliable powerplant that is more efficient than gasoline engines. This is why it is the
choice for heavy duty vehicles like trucks, buses, heavy equipment, commercial
fleet, some ships and gensets. A gasoline engine cannot match the sturdiness of
Modern technology has however shown us how polluting petro-diesel engines are. Top on the list of its detrimental
emissions are Carbon Monoxide and Carbon Dioxide, Particulate Matter or soot,
Nitrogen oxides and Sulfur. Carbon is the main component responsible for global
warming and the subsequent climatic natural disasters. Particulate Matter is a
known carcinogen and Nitrogen oxides contribute to the deterioration of the
ozone layer. Nitrogen oxides though, is easy to control by use of normal catalytic converters. Nevertheless, the diesel engine was designed to run on vegetable
oil and can safely do so by use of Biodrive’s simple, Philippines-patented
Be reminded though that this is not Biodiesel.
The Biodiesel making process reduces the viscosity of vegetable oil through
transesterification. Transesterification has the following disadvantages:
The danger of explosion if not proper procedure is strictly followed
It is also a pollutant that emits even higher Full Lifecycle Pollutants than
petro-diesel. The entire lifecycle emissions or Ecobalancemust be considered too.
It is more expensive than petro-diesel that is why a biodiesel law had
to be enacted to force manufacturers to blend this with petro-diesel.
4. Ethanol and other chemicals used in transesterification that may be left in the biodiesel mixture*, is extremely poisonous and lethal to man.
How it works
First, the vegetable oil fuel must be "clean and dry." It is necessary that this fuel oil is pre-processed properly before it is filled in the vehicle's fuel tank. By "clean" it means it has been filtered and particles greater than 5 microns had been removed. "Dry" means that water had been removed from the oil. What we watch out for is water that is suspended and emulsified in the oil which cannot be removed by simple gravity settling. Remember that included in the oil are all the things we put in when we cook,as well as those excreted by the ingredients. These are salts, defrosted ice, seasonings, animal fats among others. Take a look at our Mini Waste Vegetable Oil Processing System small enough to use in a home yet fast enough to be used by a fleet of Public Utility Jeepneys.
On the vehicle, fuel is put in two separate fuel tanks. One
for diesel and the other for vegetable oil. A small 18 liter auxiliary tank is
installed as container of diesel, while the original tank is used as vegetable
oil fuel tank. The driver warms up the engine on diesel then switches to
vegetable oil (vegoil) once the ideal engine temperature is reached. Vehicle is
then driven normally on vegoil.
To be able to be safely combustible, the vegetable fuel must pass through several Biodrive equipments installed in the vehicle before it is injected into the engine.
This may be inconvenient to private users that is why our main target are commercial fleet and environmentalists.
A Pure Vegetable Oil system without switches is also available for Mercedes Benz 79 to 84 models. As of now, this type of conversion is limited to these models as they have been tested to work due to the durable build of Mercedes injection pumps during these model years. Other diesel engines may also use a switchless conversion system but must blend the vegoil with diesel.
Our kit’s principles have been successfully
tested worldwide with millions of combined kilometers run.
We will add to this list as soon as we get permission from those who own the vehicles tested and those who did the tests.

In Germany, they already have a government
mandated vegetable oil standard for fuel. In their country, they
value the environment so much that they have slapped diesel higher taxes
resulting in a pump price that is so high that it’s even cheaper to buy brand
new cooking oil at the
supermarket that is refined, bleached and deodorized (RBD) and use this as fuel. New cooking oil for human consumption like those sold in groceries is rbd.
In the United States, new vegetable oil is
still more expensive than diesel. Waste vegetable oil from restaurants on the
other hand, are collected by licensed disposal companies to whom the
restaurants have to pay a service fee. Normally it is on a per dumpster-full or
per pound basis. Disposal is expensive for the restaurant owner so they are happy
to give the used vegetable oil away for free.
In the Philippines, the waste vegetable oil
from restaurants and food factories are bought by traders. Sometimes, though, the price gets so high (including
agent's commissions, logistics, etc.) that the traders would have to sell these to food
peddlers and illegal food processors who use the dirty oil again for human
consumption. I have observed and interviewed several peddlers and vendors in
different locations in the country and they openly admit that the oil they use
is waste oil from popular restaurants. In fact, some boast about their "prestigious" sources. These vendors sell a variety of dishes
to the public, from fishball, squidball, kikiam, fried chicken, chicken
innards, hopia and others all using waste vegetable oil. Consumption of this
type of oil has been attributed to cancer and contains metals, dirt, bacteria,
molds, free fatty acids beyond levels considered safe for humans. The use on
this type of industry for waste vegetable oil is also the factor that increases
the market price of used vegetable oil in the Philippines market. This we
believe must be stopped.
We at Biodrive use preselected waste vegetable
oil and process this by the use of several stages of equipment to ensure that
the fuel oil is clean and water-free. Suspended water in the fuel oil can cause
corrosion of steel components and solidification of the oil. We have researched
and tested our equipments to be the best, cost-effective solution to clean
waste vegetable oil.
Sustainability of Waste Vegetable Oil as Fuelin the Philippines
Waste vegetable oil as fuel is limited to the
quantity of used oil that could be collected. We therefore must prioritize
which segment has the most benefit to society and target this niche in utilizing this now valuable resource. In
order of priority, we believe this should first be the socially sensitive
PUJ/AUV Taxis sector followed by City Trucks (4 wheeler and 6 wheeler),
Generators and then Private AUV diesels. We leave the PU Buses out of the
equation as there are now viable alternatives one of which is CNG (Compressed Natural Gas), and these
bus companies are profitable enough to invest in new buses that are CNG
capable. Sedan taxis on the other hand have gasoline engines and can convert to
Big commercial trucks are not in the priority list as they will consume too much of this resource and therefore must use other alternative sources of energy which we are presently working on.
We have devised an innovative collection plan for Used Cooking Oil involving every sector of society. Biodrive's projected massive collection and distribution system transcends political boundaries and relies on government participation for the good of their constituency and the economy.
Our Thoughts on PUJ Conversion to LPG
PUJ's have diesel engines. Present LPG Conversion Kits being offered to Jeepney groups and government have been originally designed for gasoline engines. They have therefore devised 30% LPG Conversion that injects only small amounts of the fuel to the engine. Or, they can go 100% LPG by changing the sturdy diesel engine into a gasoline type.
Aside from conversion cost, the issue that must be addressed is related to durability of the LPG-converted gasoline engine when applied to typical Philippines jeepney operation. PUJ's normally run about 100 kilometers a day on stop-and-go traffic under various engine loads and driving styles.
As per our own Drive-Cycle Studies, the most applicable engine type for Jeepneys is the durable diesel engine. What is needed only is a cheaper and cleaner fuel that will preserve the diesel engine's original design that has made it the workhorse of industry for many generations. We believe that running on pure vegetable oil will provide years of durable performance to this engine.
Even for 20% LPG Conversion, slight overheating of the engine is immediately experienced. Additional studies must therefore be made to see the effects on the engine's longevity. But if the diesel engine can be converted to 100% LPG at a minimal cost, then that is another story that may be useful to those who can no longer be accommodated to convert to vegetable fuel.
