ATG Vegetable Oil-Kit 

Converting Diesel Vehicles to Straight Vegetable Oil (SVO/PPO) with the ATG 2-tank system!
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 ATG conversion kit is available in 12 and 24 volt models and is supplied with detailed installation instructions.
Following components are included in delivery:
controller (mode auto or manual switching), electric switching unit (tank switching, flush/vent) with integrated electric fuel preheater (Diesel-Therm), temperature switch (regulates the temperature), control electronics (diesel quick purge, acoustic warning), heat exchanger (fitted in water circuit), fuel lines, fuel filter, relays, pre-assembled cable loom with connectors, fuses and protective caps, miscellaneous materials, detailed installation instructions.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.

Why Converting?

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.
At last for a long-term and smooth operation with vegetable oil a conversion is mandatory.
We offer with the ATG SVO conversion 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
- additional fuel tank (optional)
- electric switching unit
- electric fuel preheater
- heat exchanger
- control electronics
- pre-assembled cable loom

Fuel Tanks(Fuel tank)

The additional fuel tank is available in different forms and sizes and can be mounted at any suitable place. The main tank is filled with vegetable oil and the secondary tank with diesel. It is also possible to leave the original tank as the diesel tank and to fill the additional tank with vegetable oil.
The electric 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.

Why Vegetable Oil?

In 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 fuel. 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 expensive.

As 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.
Recycled or used vegetable oil (WVO waste vegetable oil) can also be used provided that it has been cleaned and filtered (min. 1 µm)
