摘要：With the depletion and pollution of diesel fuels, researchers are concentrating much for the development ofrenewable alternative fuels for the existing diesel engines. Among all alcohols are found to be best because they areproduced from sugarcane and are renewable in nature. But due to the properties of alcohol fuel, it is difficult to blazethem in the existing diesel engines. So, an insulated engine is developed with the insulation of the important enginecomponents, which reduces the ignition delays and improves the thermal efficiency. In the present work experimentsare conducted with brass piston insert with maximum number of grooves on the piston which generates highertemperatures in the combustion chamber. This plunge the volumetric efficiency and more increases the frictional horsepower owing to thinning of lubricants. Therefore this drop is compensated by turbocharging. Further in order towithstand for higher temperatures in the engine, new lubricants are developed. These lubricants are blended withdifferent percentages of Teflon based additives (TBA) and analyzed the frictional losses to find the best performed oil.Tests are conducted on a single cylinder 4-stroke, water-cooled 3.68 KW Kirloskar diesel engine with 165 bar fuelinjection pressure with alcohol as a fuel.
