“…Soybean biodiesel indicated faster ignition, lower pre mixed spike and lower peak pressure compare to diesel fuel due to the higher CN and less heating value of biodiesel when the same mass of fuel injected (Kim et al 2008). The biodiesel fuels emit substantially lower NO emission specifically when EGR is used [Gerardo et al 2011, Song 2012). …”

For economic and social development of any country energy is one of the most essential requirements. Continuously increasing price of crude petroleum fuels in the present days coupled with alarming emissions and stringent emission regulations has led to growing attention towards use of alternative fuels like vegetable oils, alcoholic and gaseous fuels for diesel engine applications. Use of such fuels can ease the burden on the economy by curtailing the fuel imports. Diesel engines are highly efficient and the main problems associated with them is their high smoke and NOx emissions. Hence there is an urgent need to promote the use of alternative fuels in place of high speed diesel (HSD) as substitute. India has a large agriculture base that can be used as a feed stock to obtain newer fuel which is renewable and sustainable. Accordingly Uppage oil methyl ester (UOME) biodiesel was selected as an alternative fuel. Use of biodiesels in diesel engines fitted with mechanical fuel injection systems has limitation on the injector opening pressure (300 bar). CRDI system can overcome this drawback by injecting fuel at very high pressures (1500-2500 bar) and is most suitable for biodiesel fuels which are high viscous. This paper presents the performance and emission characteristics of a CRDI diesel engine fuelled with UOME biodiesel at different injection timings and injection pressures. From the experimental evidence it was revealed that UOME biodiesel yielded overall better performance with reduced emissions at retarded injection timing of -10° BTDC in CRDI mode of engine operation.

“…The parameters of the fuel spray and the characteristics of biofuel injection have been studied in a great number of works (Kavtaradze 2008;Broze 1969;Whitelaw et al 2002;Kutovoj 1981;Sirignano 2014;Stiesch 2013;Valentino et al 2011;Bang, Lee 2010;Desantes et al 2009;Mancaruso et al 2011;. In determining these parameters, the methods of optical diagnostics are often used.…”

& Sergey Yakovlev (2015): The influence of the fuel spray structure and dynamics of its formation on surface combustion of biofuels in diesel engines, Transport, Abstract. The paper presents the results of the experimental investigation of the structure of the fuel, rapeseed oil and diesel fuel sprays obtained by analysing their optical density. The results are obtained by investigating a conventionally designed fuel supply system and a high-pressure common rail system. The experimental data on the velocity and length of fuel sprays are given. The study has shown that when high pressure fuel supply systems are used, the fuel spray is increased by about three times, while its area is increased up to 50% and homogeneity is also higher. As a result, selfignition delay time is reduced and the combustion process is intensified. The methods, taking into consideration the specific character of using the alternative types of fuel and high pressure systems, which have been tested in the experimental conditions, are suggested for calculating the time of self-ignition delay. The applied methods allow us to reduce the error of determining self-ignition delay time up to five percent. Based on the calculated data, the factors limiting the ignition of the sprayed fuel have been defined.
