Abstract: This article is a literature review of the effect of different fuel additives on performance and emission characteristic of CI engine fuelled with blend of nanoparticles and diesel. This study is based on the reports of researchers who published their researches. It was reported that metal based additives improves emission and performance of a diesel fuel depending upon rate of additives. Use of multifunction additives for diesel will lead better fuel conservation and emission control takes place. Engine performance values changes little bit, but exhaust emission profile was improved. The addition of cerium oxide nanoparticles, with the modified biodiesel at different dosing levels of the additives showed an improvement in the efficiency of the engine. HC emission and NOx emission were reduced with the use of fuel based additives.
1. Introduction Nanofuel is a renewable and eco friendly alternative diesel fuel for CI engine. Nanofuel has higher viscosity, density, pour point, flash point and cetane number than diesel fuel. Using optimised blend of nanoparticles and diesel can help to reduce some significant percentage of the worlds dependence on fossil fuels without modification of CI engine. Moreover additives are an essential part of today fuels, together with the carefully formulated fuels composition. They contribute to efficiency reliability and long life of an engine Such as using optimised blend of nanoparticles and diesel instead of conventional diesel fuel significantly reduces emission of particulate matters (PM), carbon monoxide (CO), sulphur oxides (SOx), and unburned hydrocarbons (HC). With the use of fuel additives in the blend of nanoparticles and diesel improves performance, combustion and also improves fuel properties which enhance the combustion characteristics.

2.1 Engine Performance. Researchers and scientist have used different nanoparticles additives in diesel fuelled in CI engine. A brief study of the effect of these fuel additives is presented here. Many researchers have reported that the performance of the mixture of nanoparticles and diesel is higher when additive is used. Ajin C. et al [1] investigated that the use of cerium oxide nanoparticles in diesel engine. A single cylinder four stroke water cooled CI engine was used in test. The researchers found that the flash point decreases in volatility of fuel with addition of nanoparticles. Higher flash point temperatures are desirable for safer handling of fuel. Addition of catalytic nanoparticles in fuel increases its flash point. Nanoparticle added fuel inherently safer to handle as compared to its base diesel. BTH increases by 6% on addition of cerium oxide nanoparticles. Kinematic viscosity increases with catalytic nanoparticles addition in fuel. S. Karthikeyan et al [2] investigated that the use of ZnO nanoparticles Grape seed oil methyl ester. A single cylinder vertical air cooled diesel engine is used in the test. In this test researchers found that BSFC values of fuel decreases with increase in load. As ZnO proportion is increased BSFC of fuel decreased at each load. Also reduction in ignition delay period is observed. Because of high surface to volume ratio BTH of fuel is enhanced. Nishant Mohan et al [3] observed the use of aluminium in base diesel. The test is carried out on single cylinder four stroke constant speed DI diesel engine. They found that the drop in SFC at higher loads when engine was fuelled with nanofuel. Reduced ignition delay and high CV of nanofuel further generate same work intensity with low consumption of fuel than diesel. It shows better thermal efficiency at higher loads. Nanoparticles addition not only enhances the CV but also promotes complete combustion due to high evaporation rates, reduced ignition delay, higher flame temperature and prolonged flame sustainance. All these factors support increase in BTH. At high loads enhancement of 9% in BTH has been observed. C. Syed et al [4] investigated the use of Aluminium nanoparticles in ISO 9001:2008 Certified Journal
