چکیده
Fuel saving and emission control in transportation is a global critical issue, so research is required to concentrate on the energy conservation of diesel engines. Generally, in an internal combustion Engine, around ۶۶ % of the total heat is lost and, around ۳۳% is used for Brake Power. It is very important to improve the energy level of the engine in the field of automobiles, and this will be shown in the heat balance sheet of diesel engines. An attempt has been made to fulfill the above requirement by adding CuO and ZnO nano-additives to pure diesel fuel and Al۲O۳ and ZnO nano-lubricant additives to SAE ۱۵W-۴۰ engine lubricant oil by sonication process. Experimental work on a vertical twin-cylinder four-stroke, water-cooled, advanced computerized diesel engine was carried out with no load to full load condition using a computerised eddy current dynamometer attachment. The performance of the engine is evaluated by considering specific fuel consumption, brake thermal, mechanical, and volumetric efficiency, and exhaust emission. Results show that Specific fuel consumption is reduced by about ۱۴.۹۸%, Brake thermal efficiency is increased by about ۱۷.۶۲%, and Mechanical efficiency is increased by about ۳.۹۴%, respectively, using both nano fuel additives and nano lubricant additives. For exhaust, the emission is reduced by ۲۰.۰۴%, ۱۰.۲۵% for CO and NOx, and increased in CO۲ by ۲۹.۱۶%. With the application of nano additives in fuel as well as in lubricating oil, the overall thermal performance can be appreciably improved, and the exhaust gas pollutant from the engine can be significantly reduced.کلیدواژه ها
