“…This strategy is effective in the reduction of the combustion noise characterising direct injection diesel engines. In any case, the variation in the pressure history inside the combustion chamber, and consequently in the heat release rate, determines an effect of the pilot injection on pollutant emission levels and in specific fuel consumption as well [1][2][3][4][5][6].…”

“…Tow et al [8] pointed out that the dwell between injections was very important to control soot production and there would exist an optimal dwell at a particular engine operating condition. Durnholz.et al [10] investigated the influence of pilot injection for a turbocharged and intercooled DI diesel engine for passenger cars. Their optimized pilot injection contained about 1.5 mm 3 of the fuel in the pilot injection independent of engine load and their optimal dwell was 15CA.…”

“…The increase in ignition delay periods is the reason for the higher cylinder gas temperature and NO x emissions [13]. When the start of fuel injection timing is retarded, the temperature and pressure are slightly higher so that the ignition delay period decreases [14,15]. Therefore, the variation in injection timing exhibits a solid effect on the combustion and exhaust emissions.…”

In this study, the effect of neat lemongrass oil [1]-diesel blends on the performance, combustion and emission characteristics of a direct injection diesel engine was investigated with different injection timings of 21° (retarded), 23° (normal) and 27° (advanced) bTDC positions by using four different fuel blends of diesel, LGO25, LGO50 and neat lemongrass oil. The experimental results show that maximum cylinder pressure and heat release rate increased with advanced fuel injection timing for all test fuels. There was a reduction in BSFC and significant improvement in the brake thermal efficiency (BTE) with advanced injection timing. Emissions from the diesel engine such as smoke and hydrocarbon (HC) were reduced but NO X emission was very high with advanced injection timing compared with other injection timings. When the injection timing is advanced, ignition delay increases, which leads to the more prominent initial phase of combustion in the premixed region. In the light of the experimental results, the optimal injection timing determined for LGO-diesel blends was found to be 27° bTDC.
