Why Vegetable Oil?
light of rising fuel prices and the climate change alternative fuels such as vegetable oil offer
an inexpensive and ecologically friendly alternative to conventional diesel
Straight vegetable oils (e.g. rape oil, canola oil, colza oil, soya oil, sun
flower oil, hemp oil, palm oil) are CO2-neutral, sulfur free and nontoxic. They should not be compared
with biodiesel (RME). Biodiesel is chemically produced and substantially more
a rule fuel consumption and engine power with vegetable oil remains the
same. Smaller quantities of vegetable oil can be purchased in any
supermarket or wholesale store. In the long term, it is more preferable
to purchase vegetable oil from suppliers (e.g. oil mills) in the
region. As vegetable oil is a natural product (foodstuff) it is usually
not subject to a mineral oil tax.
Straight vegetable oils have a
higher viscosity and ignition temperature than diesel fuel or biodiesel and
therefore must be heated when operating a diesel engine.
Vegetable oils, which have not
been heated, lead to difficulties starting the engine and have negative
effects on the engine´s performance and life cycle. Cold, viscous vegetable
oil strains the injection system and burns incompletely. In the long term the
unburnt fuel leads to deposit in the combustion
chamber of the motor.
last for a long-term and smooth operation with vegetable oil a conversion is mandatory.
We offer with our SVO/WVO
kit (two-tank system with fuel preheating) a well proven solution for
operating diesel engines with untreated vegetable oils. In different versions
available the conversion system
fits for almost all diesel
vehicles and engines.
The main components are
Controller (approx. 7 x 5 cm)
The additional fuel tank is available in different forms and sizes (see
and can be mounted at
any suitable place.
switching unit is used to
switch between the tanks and for flushing the fuel system.
In order to protect the cold
engine and the injection system, the engine starts off using diesel fuel.
As soon as the
engine reaches its operating temperature, it will be switched automatically from diesel to
vegetable oil. This results in a smooth
transition from diesel fuel to vegetable oil.
The heat exchanger (fitted in water circuit)
heats in combination with the electric fuel preheater the vegetable oil to an
optimum temperature. The heated fuel relieves the injection pump and is finer
vaporized by the injectors. It ignites and burns more efficiently, resulting
in fuel savings and less wear and tear on the engine.
As long as the motor has its
operating temperature, it can be stopped and started in vegetable mode. Only if
the vehicle is going to sit for longer than 1 hour, it should be switched back
over to diesel shortly before the end of the journey. In this case an
automatic activated quick purge flushes the fuel system and the injection pump
shortly with diesel fuel and ensures a cold start without any problems.
To prevent an unintended stop in
vegetable mode, a short buzzer signal reminds to switch back to diesel.
ATG conversion kit is available in 12 and 24 volt models and is supplied with detailed installation instructions.

FAQ - Frequently Asked Questions
Can my vehicle be
converted with the kit?
The ATG Vegetable Oil-Kit is suitable for
diesel engines with in-line or distributor pumps from Bosch (except for type
VP44), Diesel-Kiki, Nippon-Denso or Zexel. The
conversion of diesel engines with Bosch VP44-injection pump, high-pressure fuel injection
like unit-injectors pumps or common-rail-technology is only possible through skilled ATG Conversion Partners.
The size of the additional
fuel tank (see
depends on the vehicle type and the available space.
If you have any further questions, please do
not hesitate to contact us.
Where can I order the
The conversion kit can be
ordered directly from ATG.
Where can I have my
The conversion can be performed by any reputable garage/mechanic.
The installation requires an
understanding of diesel engines and should be installed by a skilled
specialist (e.g. auto mechanic)! Nevertheless a DIY
(do-it-yourself) conversion is also
possible. For your own protection, please check with the
appropriate authorities in your country if there are specific provisions
concerning changes on the vehicle.
Is the conversion permanent?
No, it can be returned to its original state,
e.g. when selling the vehicle. The components can simply be removed within short time. All
of the components can be reused.
Are there any
long-term studies related to operating diesel vehicles with vegetable oil?
Tests and studies have shown that heated
vegetable oil has nearly the same properties as diesel fuel and burns just as
effectively in most engines. On the strength of past experience almost every
diesel engine can be driven with straight vegetable oil after a conversion,
provided that the motor is maintained and in good repair (compression, fuel
injectors, glow plugs, ...).
Can I operate my
vehicle on vegetable oil during the winter months or at freezing temperatures?
Pure, untreated vegetable oil is getting viscous
and sticky at freezing temperatures. Depending on the type and the properties
of the vegetable oil, this condition will happen sooner or later. In order to
prevent the vegetable oil from gelling in the tank or fuel lines, a mixture of
vegetable oil and normal diesel fuel is recommended during the winter months.
How does vegetable oil effect the
Usually, the engine’s properties (operation,
performance, consumption, ...) remain unchanged.
Can parking heaters operate with
Parking heaters are not suitable for operating
with vegetable oil. If your vehicle has a parking heater, you should consult
with the manufacturer beforehand to see whether an additional conversion is
possible. With the two-tank system, parking heaters can still operate on
How expensive is vegetable oil and where
can I purchase it?
Vegetable oil is a foodstuff and usually
not subject to a mineral oil tax. Vegetable oil is a natural product and an
inexpensive alternative to conventional diesel fuel. Smaller quantities of
vegetable oil can be purchased in any supermarket or wholesale store. In the
long term, it is more preferable to purchase vegetable oil from suppliers (e.g.
oil mills) in the region. Recycled or used vegetable oil
(WVO waste vegetable oil) can also be used provided that it has been cleaned and filtered (min. 1 µm).
Is it generally permitted to drive using
For your own protection, please check with
the appropriate authorities in your country if there are specific
provisions prohibiting the use of vegetable oil. This is
also to be done for any changes on the vehicle to be converted.
What is the difference
between vegetable oil and biodiesel?
All biofuels (e.g. vegetable oils) are CO2-neutral and free of sulfur and
pollutants in their pure, untreated state.
Additional advantages of vegetable oil
- water reactivity 0
- flash point aprox. 300°C (reduces the risk
of fire or accident)
- requires less energy to produce
- locally produced
- protection of limited fossil fuels
Rapsmethylester = RME
Biodiesel is chemically produced and substantially more
expensive than plain vegetable oil. A problem
is the durability of plastic and rubber components (sealings), which come into
contact with biodiesel. If biodiesel is used in a system that has not been
adapted, leakages on the fuel system and defects on injection pumps are the
most frequently troubles. When using pure,
untreated vegetable oil, these problems will not occur.
