Effect of Biodiesel (B-20) on Performance and Emissions in a Single Cylinder HSDI Diesel Engine

Oxides of nitrogen emissions from biodiesel-fuelled diesel engines

“…They further emphasize the inconsistency reported in the literature about certain trends between the fuels. This is highlighted by the notion that Monyem et al [58] observe similar behavior as Szybist et al [71], yet Nagaraju et al [94] observe differing behavior.…”

“…For example, Nagaraju et al [94] show no statistical change in start of injection between bio-and petroleum-based fuels, yet show a 29% shorter ignition delay (about 2 crank angle degrees) for B20. The lack of change in injection timing may be attributed to their use of a common-rail fuel system, which is consistent with data shown in Fig.…”

“…Suryawanshi and Deshpande [95] report slightly higher heat release rates of various blends of pongamia oil methyl ester at standard injection timings compared to diesel fuel. Nagaraju et al [94] report, on average, 8% higher peak rate of heat release of B20 during premixed combustion than petroleum diesel. Similarly, they [94] report higher rates of diffusion combustion with B20, which they also observe as resulting in higher exhaust gas temperatures.…”

Similarly, they [94] report higher rates of diffusion combustion with B20, which they also observe as resulting in higher exhaust gas temperatures. They attribute these changes in combustion characteristics to the presence of oxygen in the fuel and late burning of heavy compounds found in biodiesel.…”

“…For biodiesel, the ignition delay is generally shorter than that for petroleum diesel [21,9,15,22,[23][24][25][26][27]. For example, Nagaraju et al [25] show no statistical change in start of injection between bio-and petroleum-based fuels, yet show a 29% shorter ignition delay (about 2 crank angle degrees) for B20.…”
