| Abstract | (57) Abstract: A fuel additive composition for improved combustion of liquid fuel comprises a solution of a polymer of iso olefins in the molecular weight rang© of 100 to 3000, in a solvent, such as a petroleum solvent. The solution is uniformly dispersed in a fuel in a concentration of 100 ppm to 3 percent by volume of the polymer in the said fuel. PRICE: THIRTY RUPEES |
| Full Text | This invention relates to a fuel additive composition for improved combustion of liquid fuels and a method of preparing the same. The composition proposed herein improves the combustion of liquid fuel mass. The said fuel additive composition contains a homo- or CO- polymer of is olefins and the said polymer rapidly disintegrates at the bulk fuel temperature in the combustion zone, atomizing the fuel and enhancing the air-fuel mixing. The enhanced air-fuel mixing reduces emission levels of smoke, particulates and carbon monoxide in the exhaust. The letdown of carbon on the injection nozzle and burner tips is also reduced. Disintegration of the additive again helps to reduce knocking when used in an engine. The fuel additive composition for improved combustion of liquid fuels, according to this invention, comprises a solution of a polymer of iso olefins in the molecular weight range of 100 to 3000, in a solvent, such as, a petroleum solvent, the said solution being uniformly dispersed in a fuel in a concentration of 100 ppm to 3 percent by volume of the polymer in the said fuel. Example: additive for diesel engine was prepared by dissolving 0.4 litres of polyisobutylene of average molecular weight of 1300 in 0.6 litres of a petroleum solvent (mineral turpentine oil of 0.796 density at 15 deg C, distilling between 176 deg C and 230 deg C). The additive was added at 1 volume per cent to diesel and tested in a single cylinder, four stroke, air-cooled, vertical, direct injection diesel engine with a rated power of 4.4 KW at 1500 rpm, coupled to a Benz Eddy current Dynamometer for torque measurements. Smoke emission was measured by a standard Bosch smoke measuring apparatus. The improvements in Specific Fuel Consumption (SFC), exhaust temperature and smoke, observed during the test are tabulated hereunder: The terms and expressions in this specification are of description and not of limitation, there being no intention in the use of such terms and expressions of excluding any equivalents of the features described, having regard to the scope and ambit of this invention. We Claim: 1,A fuel additive composition for improved combustion of liquid fuels comprising a solution of a polymer of iso olefins in the molecular weight range of 100 to 3000, in a solvent, such as, a petroleum solvent, the said solution being uniformly dispersed in a fuel in a concentration of 100 ppm to 3 percent by volume of the polymer in the said fuel. 2.A fuel additive composition as claimed in Claim 1 wherein the solution is polyisobutylene of average molecular weight 1300 dissolved in mineral turpentine oil. 3.A fuel additive composition substantially as herein described with reference to, and as illustrated by, the Example. 4.A method of preparation of a fuel additive composition for improved combustion of liquid fuels comprising the steps of dissolving a polymer of iso olefins in the molecular weight range of 100 to 3000 in a solvent, such as, a petroleum solvent; and dispersing the same uniformly in a fuel in concentrations of 100 ppm to 3 percent by volume of the polymer in the said fuel. 5.A method as claimed in Claim 4 wherein the said polymer is polyisobutylene of average molecular weight 1300, said polymer being dissolved in mineral turpentine oil. 6.A method of preparation of a fuel additive composition for improved combustion of liquid fuel substantially as herein described with reference to, and as illtistrsted by the Example |
