Fuel consumption is the single largest variable cost during field operation of tractors and also one of the most influential parameters controlling the salability of the vehicle, particularly in developing countries. Hence there is a great need for development of a system which c...
Gear-up-throttle-down (GUTD) technique as a solution to match the load on tractor during field operation for better fuel economy. Experiments have proved that GUTD approach can save 20 to 30% fuel. Previously a DFE has been developed by keeping in mind the low education level of...
