ABSTRACT: In the previous part we were told that plastic oil 20% blend was optimum. This paper presents the three nano additives which are Metal Based, Oxygenated and Organic Additives which we have selected as Metal-Based as Titanium Oxide nano additive because of that plastic Oil viscosity Decreases as well as increases flowbility,and reduce the emissions. We have some techniques to reduce Pollutions that are EGR, Exhausted After Treatment and Compression Ratios All are Old techniques. The New Technique is Adding Nano Additives with plastic oil.Tio2 nanoparticles are sprinkle in the emulsions with various dosage intensity of 25, 50, 75, and 100ppm. A single-cylinder, four-stroke CRDI diesel engine is made to run on different fuel engrossment to swotting the end result of emission hallmark of the fuel. The test engine was exercise under constant engine speed (1500 rpm) and different engine load test conditions. According to the experimental results, fuel blends with biodiesel fuel emission aggravate NOx and diminish the CO, HC, and smoke emissions contrast with the wpo20 fuel. The experimental result shows heat release rate and cylinder peak pressure obtained was of 15.38 % and 40 % for WPO20+50ppm tio2. And also observed that WPO 20+50ppm tio2 has 5.72 % higher brake thermal efficiency was found as compared to wpo20% at full load. On the other hand 100ppm tio2 blend also resulted increase NOx emission by 25%, smoke opacity decreases by 46% as well as higher for full load. But UHC and CO emissions are slightly decreased with compared the wpo20 fuel.

Keywords: CRDi engine; combustion; injection timing; Tio2 nano additive : emissions; performance EGR.
