“…From the findings, a reduced trend of CO was observed for bimetallic nanoparticles with the increment of nanoparticle concentration level. However, some researchers reported that higher dosage nanoparticles addition into diesel fuel could worsen the engine performance and hence rise in exhaust emissions [4,17,18]. It is seen that the availability of AgNO 3 in the mixture contributed to the reduction of CO emission for whole test fuels.…”

This paper reveals the results of metallic-based nanoparticle's effect on the performance, emission, and vibration of a diesel engine. Various metal-based nanoparticles such as Nickel (II) nitrate hexahydrate (Ni(NO 3 ) 2 .6H 2 O), Silver nitrate (AgNO 3 ), and Manganese (II) nitrate hydrate (Mn(NO 3 ) 2 .xH 2 O) were chosen as fuel additives into diesel fuel and dosage with 25 and 50 ppm. In experimental tests, to identify the combined effect of silver nitrate on manganese and nickel, silver nitrate was chosen as a reference element in each mixture, thereby creating 4 different test samples. Engine tests were conducted in a single-cylinder diesel engine. The results revealed that values of specific fuel consumption, carbon monoxide, hydrocarbon, and oxides of nitrogen emissions with the increase in the dosage level of nanoparticles into diesel fuel were reduced considerably for all test fuels. Also, vibration and sound pressure level features of the diesel engine were reduced with the increasing dosage of nanoparticle additives.

“…Furthermore, because of the excellent air-fuel mixing. (11). The additional oxygen content in the ZONP increases the cylinder combustion temperature which lead to increases in NOx emissions [30] .Also increasing the engine load leads to an increase in temperature in combustion chamber resulting in increased in NOx emissions.…”

The nanoparticles diesel additives played a major role in enhancing diesel performance by improve its efficiency and alter the emissions of CO, NOx and HC including several hazardous air pollutions. Zinc oxide nanoparticles (ZONP) is used in diesel engines which blended with diesel by using ultra sonicator and a mechanical homogenizer to achieve good dispersing. Five concentration of ZONP are studied in this study. To demonstrate and access the enhanced performance of the nano-diesel blend a comparison of fuel consumption, brake power and engine efficiency with base diesel are made. The addition of ZONP promote combustion by increasing engine performance and reducing the emissions. To evaluate the impact of ZONP on engine performance and environment, several experiments performed on the diesel engine at 1400 rpm which is kept constant throughout the experiment with different range of loads. The results show clearly that by adding the nanoparticles, namely ZONP into the diesel fuel has significant improvement of high the brake thermal efficiency (BTE) and low Brake Specific Fuel Consumption (BSFC) as compared to diesel. Also, the average reduction in CO is 33% for high ZONP concentrations and applied high loads while average increases in CO2 is 8%, and NOx is 33% and more for high ZONP concentrations and applied high loads compared to pure diesel. Furthermore, 100% eliminated HC is observed when compared to pure diesel at different loads.

“…Diesel engines are utilized in various sectors like agriculture, transportation and industry due to lower specific fuel consumption, higher thermal output with high compression ratio, stability and low operational and maintenance expense. Despite such advantages, it increases environmental concerns in harmful emissions such as particulate matter and NOx causing serious health problems and environmental issue [1][2][3]. Therefore, researchers have concentrated their studies on improving fuel characteristics in order to achieve better fuel economy, engine performance and lower exhaust emissions.…”

“…An appropriate nanoparticles concentration also enhances fuel properties including viscosity, density, heating value, cetane number [6][7][8][9]. Whereas nanoparticles addition at higher concentrations can worsen the performance and result in increment of exhaust emissions [2][3][4]. Vibration and noise features play an important role on combustion characteristics of internal combustion engine.…”

In current study, exhaust emission, vibration and noise features of diesel engine with addition of metallic based nanoparticles into diesel fuels were investigated experimentally. Various nanoparticles called as silver (II) nitrate (AgNO3), manganese (II) nitrate hydrate (Mn(NO3)2. xH20) and nickel(II) nitrate hexahydrate (Ni(NO3)2.6H2O) were used as an additive to diesel fuel at 25 ppm and 50 ppm dosing level so as to obtain six different fuel samples. Diesel engine with air-cooled and a single cylinder were utilized for engine tests altering engine speed from 1200 to 2800 rpm at the intervals of 400 rpm. The results demonstrated that of the nanoparticle addition did not remarkably affect the physicochemical features of the diesel test blends. But, the addition of nanoparticles slightly raised viscosity, cetane number and the heating value of test fuels especially, at the higher nanoparticle concentrations. In all experiments, with nanoparticle added blend fuels, CO, HC, NOx emission values and brake specific fuel consumption (BSFC) declined in parallel with the increase in nanoparticle concentration. In addition, it was shown that the Sound Pressure Level (SPL) and vibration characteristics of the engine block also decreased with increasing nanoparticle concentration of test fuels. As a result, AgNO3 addition to diesel fuel has an effective role in both reducing emission and vibration values and reducing BSFC values.
