Multifunctional All Terrain Transport Vehicle, powered by PPO and PV.

(by NA, November 16th 2016)

GreenTrac is a multifunctional all terrain transport vehicle and light agricultural tractor with 4 x 4 electric hybrid drive. The onboard standard generator is driven by a small diesel engine converted to run on Pure Plant Oil (PPO). It has 8m² flexible PV panels on the roof, charging the battery pack.

The vehicle combine development and disaster preparedness for roadless areas.

Besides solving transport tasks, it can serve as power supply for mini grids.

This unique vehicle has been developed by the Norwegian Svein Olav Lie, owner of the company Greentrac. The vehicle comes in several versions from 4 to 8 tons of payload, and is specifically designed to perform transport tasks in very rough terrain. The vehicle carries the name GT is an abbreviation Getting There, implied that the vehicle appears even where ordinary Off-Road vehicles have to give up.

The On-board 6kW KUBOTA genset, converted by DAJOLKA to run on Pure Plant Oil (PPO).

The genset is converted with a 1-tank system, which means that it starts and operate on PPO just as if it was running on diesel. The main components in the conversion system is A) coolant-fuel heat exchanger, B) Fuel filter with electrical heating, C) Special injector Nozzles, D) Special glow plugs and E) electrical fuel lift pump. It can operate on new PPO or good quality waste cooking oil(WCO), and it can still run on diesel or any mixture of the mentioned types of fuel.

The idea is that the vehicle can perform transport tasks in developing countries, so that poor farmers can transport their goods to local markets, where goods can be sold. 

In the latest version with Diesel / PPO-electric hybrid technology, the vehicle can also serve as energy supply at night when there is need power for light in the otherwise dark villages, or the operation of machines in workshops or processing of agricultural crops. The vehicle is equipped with a battery pack that can handle the power supply when the need is very small, so that the diesel / PPO engine can be switched off, thus saving large amounts of fuel as it costs to have traditional gensets to run idle. The battery pack simultaneously provides the possibility to store energy from wind turbines or solar cells can be stored and used later. The Hybrid technology for the GT vehice has been developed to the Swedish company Thordab and marketed by Elforest.

GT vehicle is unique in many ways, which can be highlighted:

  • Independently permanent 4-wheel drive using. Electric hub motors at each wheel.
  • No mechanical parts in the transmission or control.
  • High ground clearance combined with highly flexible suspension, yet relatively low loading height.
  • Rear wheels follow the front wheels track(not all models)
  • Very stable in sloping terrain due to low center of gravity.
  • Lightweight yet large load capacity, 2 times its own weight
  • Can act as stationary power supply.
  • Powered by small standard generator sets, either on petrol, diesel or vegetable oil.
  • Can store power from renewable sources.
