An Enhancement in Finding the Characteristics of CI Engine with Methyl Ester Mango seed Biodiesel as Blends-A Review

Biodiesel is a low-emissions diesel substitute fuel made from renewable resources like vegetable oils. India is not self-sufficient in petroleum and has to import about two third of its requirements to introduce one of the solutions to the current oil crisis and toward off any future energy and economic crunch is to explore the feasibility of substitution of diesel with an alternative fuel which can be produced in the country on a massive scale to commercial utilization. B20 (20% of biodiesel blended with 80% of conventional diesel) is a very popular biodiesel blend that can be used directly in diesel engines without any major engine modification. Biodiesel blends, in general, reduce the brake thermal efficiency slightly and lower PM, HC, COx emissions as compared to conventional diesel fuel.the fuel consumption and the emission characteristic of a twin cylinder diesel engine that are using Mango seed oil blended with Ethanol & compared to usage of ordinary diesel that are available in the market. This paper describes the setups and the procedures for the experiment which is to analyse the emission characteristics and fuel consumption of diesel engine due to usage of the both fuels.Diesel engine is able to run with Mango seed oil blended with Ethanol but the engine needs to run by using diesel fuel first, then followed by Ethanol and finished with diesel fuel as the last fuel usage before the engine turned off. The performance of the engine using Mango seed oil blended with ethanol as fuel compared to the performance of engine with diesel fuel.
