Experimental And Prediction Analysis Of Diesel Engine Fuelled With Tio2 Nanoparticles Dispersed Semecarpus Anacardium Biodiesel

Abstract

In recent years, biodiesel has become very important for use in diesel engines due to its economic and environmental advantages. Nevertheless, biodiesel fuel has enormous potential to increase engine performance and reduce emissions. The addition of nanoparticles is an obvious way to improve the physicochemical properties of biodiesel, which can increase performance and reduce emissions. The present study focuses on the investigation of nanoparticle stability and physicochemical properties of TiO2 nanoparticles in a Semecarpus anacardium biodiesel blend. The TiO2 nanoparticles are mixed in different proportions: 50 mg/L, 75 mg/L, and 100 mg/L. In addition, dispersant (QPAN80) is mixed with TiO2 nanoparticles at a ratio of 1:1. The whole procedure is carried out with the help of an ultrasonic device. Then, the TiO2 nanoparticles with the base and dispersant are added to biodiesel blend (BD20) for the production of the nanofuel using the probe sonicator. The stability analysis and physicochemical properties are estimated for different nanofuel samples. The stability of TiO2 nanoparticles was estimated using a spectrophotometer in terms of transmission and absorption, while the physicochemical properties were evaluated using ASTM standards. It is found that the stability of TiO2 nanoparticles is better in dispersant-added nanofuels than in clean fuels. In addition, the physicochemical properties, such as cetane number and heating value of the nanofuel are found to improve as compared to base diesel and BD20. Among all tested fuels, B20 with 75 mg/L TiO2 nanoparticles and 75 mg/L dispersant showed tremendous stability compared to the other samples, and the cetane number and heating value are found to be better with the same combination newline newline
