Petroleum reserves are rapidly and continuously depleting due to this there is an urgent need to find alternative energy resources which is primarily attributed to combustion of fossil fuels. In last couple of decades, biodiesel has emerged as the most important alternative fuel to mineral diesel. Numerous experimental investigations have confirmed that biodiesel results in improved engine performance, lower emissions, particularly lower particulate mass emissions is therefore relatively more environment friendly fuel, being renewable in nature. Environmental and health effects of particulates are not simply dependent on the particulate mass emissions but these change depending upon varying physical and chemical characteristics of particulates. This paper presents an exhaustive experimental analysis of Compression ignition (CI) engine. The effect of biodiesel and its blends on exhaust particulate’s physical characteristics. Control of particulate emissions using exhaust gas recirculation (EGR) with the use of biodiesel has been critically analyzed and included in this article.
