“…Research evaluating engine performance when diesel engines were fiieled with various esters of vegetable oils has shown that the engine performance is similar to that of diesel fiiel with lower CO, HC, and particulate emissions and slightly higher NO* emissions [10,11,71,75,76,77].…”

“…Freedman et al [79] and Harrington [80] have also reported that esters of vegetable oils have high cetane numbers and that saturated esters have higher cetane number than the unsaturated esters. The estimated cetane number (calculated based on ignition delay data coUeaed in a combustion bomb) of some saturated esters, such as methyl stearate and methyl arachadate, were over 100 [79], Last et al [75] tested methyl esters of soybean oil, blended with low sulfiir diesel, in a Navistar T444E diesel engine. Their tests with the SAE 13-mode steady state test using biodiesel blends in diesel fiiel between 10% and 100% showed substantial improvements in total particulate emissions.…”

“…Although several research programs have been carried out in the last decade on the performance and emissions of CI engines, fuelled with pure biodiesel and blends with diesel fuel, most scientific literature has dealt in the past with engines equipped with conventional injection systems [8,9,10,11,12,13,14,15], and even if more recent works also examined engines with high pressure, electronically controlled injection systems [16,17,18,19,20], only few studies concerning last generation automotive engines are available. Moreover, experimental activities reported in literature are usually carried out running the engine with the original, diesel oriented, ECU calibration; a specifically adjusted ECU calibration optimized for biodiesel is rarely used [21] and the gap in engine torque output is usually recovered by increasing the torque demand through an increase of the accelerator pedal position, thus simulating a switch of the supplied fuel.…”

The effects of using a B30 blend of ultra low sulphur diesel and two different Fatty Acid Methyl Esters (FAME) obtained from both Rapeseed Methyl Ester (RME) and Jatropha Methyl Ester (JME) in a Euro 5 small displacement passenger car diesel engine on both full load performance and part load emissions have been evaluated in this paper.In particular the effects on engine torque were firstly analyzed, for both a standard ECU calibration (i.e. without any special tuning for the different fuel characteristics) and for a specifically adjusted ECU calibration obtained by properly increasing the injected fuel quantities to compensate for the lower LHV of the B30: with the latter, the same torque levels measured under diesel operation could be observed with the B30 blend too, with lower smoke levels, thus highlighting the potential for maintaining the same level of performance while achieving substantial emissions benefits.Moreover, the effects of the two different 30% vol. blends on brake specific fuel consumption and on engine-out exhaust emissions (CO 2 , CO, HC, NO x and smoke) were also evaluated at 6 different part load operating conditions, representative of the New European Driving Cycle.Both standard engine calibration (change of the accelerator pedal position) and specifically adjusted engine calibration (adjustment of the energizing time of main injection) were evaluated for part load operating conditions, highlighting a 4% average rise of fuel consumption, on a mass basis, at same fuel conversion efficiency and CO 2 emissions. A noticeable increase of CO and HC emissions at low load could also be noticed, along with a significant NO x emissions decrease when using a specifically adjusted engine calibration, and a considerable smoke emission reduction.

“…These increases were basically the result of the loss of heating value in the biodiesel fuel blends. [ 5,6,7,8,9] In the present scenario the designs of CI engine being used in automotives by various manufacturers are not properly suitable to Indian climate condition. Looking in to the vast varying atmospheric temperature range in the country it is very difficult to say that which temperature is most suited to operating condition of engines and will give the best performance levels as far as bsfc and bp is concerned.…”

Abstract-India is among those tropical countries where atmospheric temperature is having very vast range i.e. from 0°C to 48°C in various regions of the country. This vast varying temperature range may not allow the engine to perform uniformly, therefore, which temperature is most suited for operating parameters of engines and will give the best performance levels. The aim of this study is to analyze the performance of a compression ignition (CI) engine using Jatropha biodiesel and its blends with diesel as fuel on changing engine temperature to obtain best performance levels. It has been tried to investigate the optimum operating temperature of engine that will deliver the best performance level. The blends of Jatropha with diesel in varying proportions (B10, B20 and B40) are prepared and are investigated in single cylinder, four stroke CI engine computerized test rig. The results obtained on engine performance parameters i.e brake power (bp), brake specific fuel consumption (bsfc) and smoke intensity and presented graphically with respect to the engine coolant temperature at different engine loads ie of 8, 12 and 16 kg etc. The present study inferred that it is preferable to operate the engine at temperature 65˚C-75˚C to obtain best performance indicators.
