A REVIEW OF THE PERFORMANCE, COMBUSTION AND EMISSION CHARACTERISTICS OF A VCR ENGINE USING BIODIESEL WITH NANO ADDITIVES

Abstract

In agriculture and irrigation, internal combustion engines (CI engines) are potential sources of power generation. However, society is concerned about falling diesel and serious pollution laws. More emphasis needs to be placed on improving thermal efficiency and reducing the fuel consumption of CI engines; otherwise, alternative fuels are a more viable option. To boost rural development and economics, biodiesel can be used as a fuel in CI engines as an alternative to diesel. Although biodiesel is a regenerative, durable and oxygenated alternative to diesel, it results in lower engine power and higher fuel consumption. Nanofluid additives in biodiesel can simultaneously control engine efficiency and emissions. It gave brief information on numerous topics. Following ASTM standard testing protocols, a thorough investigation of the influence of nanoparticles on numerous physiochemical properties of biodiesel fuel was done. . The purpose of this review study is to look into and critically analyse the effects of nanoparticles additives on the evaporation rate, burning rate, performance, and emissions in diesel and biodiesel CI engines. By boosting heat transfer properties, the area to volume ratio, and subsequent atomization, adding nanoparticles to fuels increases the evaporation process of the basic fuel. Adding nanofluid additions to gasoline increased its cetane value and heat capacity. The proposed research will also investigate into the effects of different nanofluid additives and calorific value boosters, as well as comparing CI engine performance and emissions with other base fuels, including biodiesel. According to the findings, nanofluid additives can reduce fuel consumption and pollution by up to 50% improving combustion.
