“…Although it could be theoretically possible to achieve near zero NO x and PM emissions, in practice, it could only be achieved by a combination of close control of the combustion process and good aftertreatment systems [1]. To optimize the combustion process of conventional fossil fuel, the use of oxygenated fuels such as biodiesel has been on the spotlights as a promising additive which can significantly enhance the combustion efficiency by replenishing oxygen in the fuel rich zones due to the release of oxygen atoms from its chemical structure, thereby reducing the PM, CO and HC emissions [2][3][4]. However, the drawback followed would be the slightly elevated NO x emissions as reported by many researchers [5][6][7][8][9].…”

“…H.G. How et al [47] also noticed that a variation of vibration accelerations are very similar with the variation in peak pressure rise rate. Figure 9 shows super imposed time waves of an engine fuelled with diesel and NME at a maximum load of 12 kg, in lateral direction.…”

“…A major drop of 13.7% in RMS value of vibration acceleration is observed with B50 at an engine load of 0.86 MPa compared to baseline diesel [47]. Chiatti et al [48] utilized a vibration signal to compute the angular position at which 50% of mass is burned inside the cylinder.…”

“…The emission reduction target has led to look for cleaner fuels such as biodiesel. Biodiesel can be used either pure or blended with fossil fuel in existing CI engines without any mechanical modifications [15]. Biodiesel is environmental-friendly compared to diesel fuel: it emits lower HC (hydrocarbons), CO (carbon monoxide) and PM [16,17].…”
