New technology to bring down fuel cost!
There is a hope to bring down the increasing price of emulsified fuels by the upcoming new technology invented and tested by the Chennai-based Hydrodrive Systems and Controls. This will also help in reducing India’s dependence on crude imports.
“The technology we have developed does not use any additives or surfactant,” Hydrodrive managing director and inventor Srinivasan Gopalakrishnan said.
“We do emulsification through a molecular engineering process, which has already been covered by a patent granted in several countries including Britain, Canada, India, the Philippines and patent pending in China, Japan and the US,” Gopalakrishnan told IANS.
An emulsified fuel is a mixture of water in fuels. It is used in internal combustion engines and for combustion in boilers, furnaces and external combustion equipment. As oil and water generally do not mix, costly special additives or surfactants are used for surface tension modifications to manufacture emulsified fuels by mixing them and to retain stability for a longer period without oil and water getting separated. Hence it is costlier than the conventional diesel fuel due to the use of costlier surfactants or additives. Due to the higher price compared to the conventional diesel fuel, the emulsified fuel marketing companies are unable to push the product and are dependent upon tax incentives.
A known technology since 1900, it is considered as eco-friendly because it reduces emission. Emulsified fuels are currently sold by five European manufacturers. The fuel produced for use in the internal combustion engines has minimum 10 percent to maximum 20 percent water in diesel.
“Our technology burns 25 percent water in 75 percent diesel as against the maximum 20 percent water in the diesel emulsion achieved by existing producers,” said Gopalakrishnan, a mechanical engineer with a management degree who set up Hydrodrive in 1981.
He added that the manufacturing process developed by his firm brings down the fuel cost to much below the cost of the conventional diesel or petrol or kerosene.
“India’s Super Auto Forge Limited which manufactures cold forged/cold extruded steel and aluminum components for the automotive industry has found after six months of testing that it saves fuel.
“Similarly the technology was tested in a tractor in the US and a vehicle in Canada. Both were found working without problem. More tests are also in progress,” he said.
“We are now commercially offering the on-demand emulsification plant on a 14-year license to individual industrial fuel users to cut down their fuel expenses,” Gopalakrishnan said.
The investment on the emulsification plant would be recoverable within 10 to 12 months through savings made in fuel consumption.
Gopalakrishnan said that the new technology could help reduce India’s dependence on costly crude oil imports and will help combat fuel crisis.
