“…10 Main reason for this was the availability of additional oxygen within the biodiesel fuel molecules. 10 It was also mentioned that earlier start of combustion (SOC) due to higher bulk modulus and density of biodiesel also caused higher NO X formation. 10 Giakoumis 11 reported decreasing trend for CO, HC and PM emissions for biodiesel blends up to 50% by deriving best-fit quadratic regression curve from his statistical studies.…”

“…Reduction in maximum cylinder pressure (P max ), maximum rate of pressure rise (ROPR max ), maximum rate of heat release (ROHR max ) and cumulative heat release (CHR) were also reported with increasing biodiesel blend concentration. Pandey et al 10 conducted experiments on a JB and Karanja biodiesel (KB) fuelled 12-cylinder, 585 kW compression ignition direct injection (CIDI) military engine for evaluating wear, engine performance, combustion and emission characteristics. Higher BSFC, and lower ROHR, HC and CO emissions but higher NO X emissions were reported for KB and JB.…”

Internal combustion engine research on alternative fuels has gained momentum because of growing awareness about energy security and environmental issues worldwide. Biodiesel offers an ideal solution to these problems and is an excellent partial replacement to mineral diesel. In this study, Karanja biodiesel blended with mineral diesel has been investigated for macroscopic spray characterization vis-à-vis baseline mineral diesel by varying fuel injection pressures (50, 100 and 150 MPa). Spray developed with relatively narrower spray angle for KB20. Injector needle movement for energizing and real injection durations were also compared for diesel and KB20 at fuel injection pressures of 50, 100 and 150 MPa. Needle movement was slightly higher for KB20 because of its relatively higher viscosity. However, with increasing fuel injection pressure, the difference reduced and showed quite similar results. A 2.2 L common rail direct injection sport utility vehicle EURO-IV diesel engine was used for the experiments. Engine performance, emissions and combustion characteristics of KB20 were compared with baseline mineral diesel at (1) the rated engine speed (2500 r/min) with varying engine loads as well as (2) at the rated load at varying engine speeds (1500-3500 r/min). Brake thermal efficiency of KB20 was lower than mineral diesel. Brake-specific carbon monoxide and carbon dioxide emissions decreased with increasing brake mean effective pressure and showed increasing trend with increasing engine speeds. KB20 showed emission of higher number of particles compared to mineral diesel at all engine operating conditions. Higher oxygen content of biodiesel resulted in shorter ignition delay and slightly higher peak cylinder pressure. KB20 showed relatively longer combustion duration compared to mineral diesel at 2500 r/min engine speed.

This paper describes the requirement of the Numerical simulation of compression ignition diesel injection by the use of computer language and it also compares the performance parameter for the biodiesel such as jatropha and karanja. The Engine test was carried out in 512 Army base workshops for the experimental validations. It was carried out on SAJ dynamometer which was installed in Engine test house for testing of Engines. Performance parameters such as Brake power, Brake Torque, Mechanical efficiency, Thermal Efficiency, Pressure vs Crank angle and Heat release Rate vs Crank Angle was taken from the Engine test house. The Program code for the Performance parameter of Engine was developed in C++ language.Then the simulation was carried out. The simulation results were compared and analyzed with the experimental results. The final results was effective for compression ignition diesel injection. As we know that today's world is approaching towards computer simulated results, so the numerically simulated results will save time and money for engine testing house. Likewise we can approach towards numerical simulation for various types of Engines.

“…However, deposits formation and oxidation increases significantly for B20 diluted fuel in comparison to that of ULSD. Pandey et al [36] in a 100 h long term endurance tests conducted on a military 585 kW CIDI engine fuelled with diesel, KOME and Jatropha oil methyl ester (JOME) respectively shown with the help of atomic absorption spectroscopy and ferrography test that wear of metals were found to be lowered for both biodiesel operated engine compare to that of diesel. Raadnui and Meenak [37] have shown that wear rate of Fe, Cr, Si, and Al was similar for refined palm oil and petroleum diesel while, Cu and Pb wear rate was higher for palm oil.…”
