TVS Motor Company has secured a patent for an invention related to a cooling sytem for the rear mounted engine of three-wheelers. M Ajith, assistant controller of patents and designs, Chennai, granting the patent in an order on Wednesday, said the application meets the objections raised by the patent office and was found to be in order for grant of patent. TVS Motor produces three-wheelers under the ‘King’ brand in the country.
According to the TVS Motor filing with the patent office, the invention relates to a cooling system for a rear-mounted liquid engine of three-wheelers comprising at least a first opening for atmospheric air to enter the engine-chamber and a second opening at the rear for the hot air to exit.
Three-wheelers have a drawback: cooling of their engines is not effectively achieved, mainly because the rear-mounted engines are closeted in compartments inaccessible to cooling atmospheric air. Such engines are therefore usually liquid-cooled, but the cooling problem was largely left unsolved in view of their virutal isolation from atmospheric air.
“It is therefore, an object of this invention to augment the cooling of the known liquid cooled engines, by atmoshpheric air. By augmenting the cooling, increase in power can be achieved,” the company had claimed in the patent specification filed before the patent office.
According to the company, another object of the invention, was to dispense with the need to use any power-driven mechanism for the purpose and yet augment the existing cooling effect. The invention can readily be incorporated in motor vehicles yet to be manufactured as well as vehicles already on the road.
The company submitted that the inventive step lies in providing the first opening on the side of the body of the vehicle for an engine that is mounted in a closed compartment.
