Effects of addition of various nanoparticles on performance and emission properties of compression ignition engine with diesel and biodiesel blends as a fuel – A review study

MECHANICAL ENGINEERING

Due to growth of population, energy consumption, and global warming concerns, design and improvement of high energy efficient and low hazardous emission diesel engines have received substantial attention. In this regard, the various techniques have been employed to improve engine performance such as fuel modification, engine design alteration, and exhaust gas treatment. The purpose of fuel modification is to improve the combustion to obtain low fuel consumption and emissions , using biodiesel and its blends with diesel as a fuel reduces emissions and can be use without engine modification but there is increase in fuel consumption and decrease in brake thermal efficiency. In past few years use of nanoparticles as a fuel additive is emerging owing to its high surface area to volume ratio , oxidation capacity, thermal conductivity when dispersed in any base fuel. It has been found from the literature review that nanoparticles used with diesel ,biodiesel and its blends improves properties of fuel and promote complete combustion which improves performance of the engine as well as reduces exhaust emissions. In this review paper work has been done by detailed study of literatures to examine the effect of various nanoparticles on performance and emission properties of CI engine with diesel ,biodiesel and its blends as a base fuel.
