Production of biodiesel from crude nyamplung oil (Calophyllum inophyllum) have been done by transesterification using Al-MCM-41 catalyst. Al-MCM-41 catalyst was obtained from impregnation of MCM-41 by Al. Sodium aluminate was added to MCM-41 until pH 11.5. The mixture was heated until 110 °C for 5 days. The calcination was performed at 500 °C, and then cooled at room temperature. The Al-MCM-41 obtained was characterized using SAXRD. Morphology of the surface was analyzed using SEM. The metals content were measured using XPS. Performance of Al-MCM-41 to adsorp and desorp nitrogen was also monitored by GSA using BET model. Acidity of the Al-MCM-41 was analyzed by FTIR using absorption of pyridine. The catalytic activity was measured using gas chromatography-mass spectrometry (GC-MS). The chromatogram shows that conversion Nyamplung seed oil to biodiesel is 98.15%. The performance of biodiesel obtained was analyzed by use it to diesel engine. The biodiesel obtained was mixed with commercial diesel fuel in various volume ratios (i.e. 0, 10, 20, 30 and 100%) before used. Viscosity, flash point, boiling point, cloud point, and pour point of the mixtures were characterized. These measuring properties increase with the increase of biodiesel concentration. Optimum engine power was achieved by 10% biodiesel. The mixture of 10% biodiesel has similar characteristic to commercial diesel fuel at load until 1800 watt.

In the near future, crude oil based fuels must little by little be replaced by biofuels both in the region of the European Union (EU) and in the United States. Bearing this in mind, a Finnish-made off-road diesel engine was tested with a biofuel-diesel fuel blend in the Internal Combustion Engine (ICE) Laboratory of Turku Polytechnic, Finland. The biofuel was cold-pressed mustard seed oil (MSO). The engine operation, performance and exhaust emissions were investigated using a blend of 30 mass-% MSO and 70 mass-% diesel fuel oil (DFO). The injection timing of the engine was retarded considerably in order to reduce NOx emissions drastically. The main target was then to find out, whether the blended oxygen containing MSO would speed up the combustion so that the particulate matter (PM) emissions would remain unchanged or even decrease despite the injection retardation. As secondary tasks of the study, the NOx readings of the CLD and FTIR analyzers were compared, and exhaust contents of unregulated compounds were determined. Retarding the injection timing resulted in a significant decrease of NOx emissions, but in an increase in smoke, as expected. At retarded timing, the NOx emissions remained almost unchanged, but the amount of smoke decreased when the engine was run with the fuel blend instead of DFO. At retarded timing at rated speed, the number of ultra-fine particles decreased, but the amount of large particles increased with DFO at full load. At 10% load, however, the particle number increased in the entire particle size range due to retardation. At both loads, the use of the fuel blend slightly reduced larger particles, whereas the number of small particles somewhat increased. At full load at an intermediate speed of 1500 rpm, the PM results were very similar to those obtained at rated speed. At 10% load with DFO, however, the injection retardation led to a higher number of larger particles, the smaller particles being at almost an unchanged level. With the fuel blend, the particle number was now higher within almost the whole particle diameter range than with DFO. Considerably higher NO2 contents were usually detected with FTIR than with CLD. The shape of the NOx result curves were rather similar independent of which one of the analyzers was used for measurements. The NOx contents were, however, generally some ten ppms higher with FTIR. The exhaust contents of unregulated compounds were usually low.

Nowadays, biodiesel from non-edible feedstock is gaining more concern than edible oil to substitute diesel fuel. The purpose of this study is to investigate the performance of low cost single cylinder diesel engine fuelled by regular diesel and B5 biodiesel of castor and jatropha. The experiments were conducted to identify the performance of a low cost single cylinder diesel engine dynamometer, in terms of engine torque, engine power, and brake specific fuel consumption. It was found that these biodiesel can be used as the alternative fuel based on the performance of engine dynamometer, where the results show nearly similar with regular diesel.

Hydrogen can be a viable alternative fuel for modern diesel engines, offering benefits on efficiency and performance improvement. The paper analyses the results of a thermodynamic model developed by authors in order to study the influence of Hydrogen addition on a process like vaporization, mixture forming, and combustion at the level of diesel fuel droplets. The bi-zonal model is applied for a dual-fueled diesel engine K9K type designed by Renault for automotives. For the engine operating regime of 2000 rpm speed and 55% engine load, the diesel fuel is partially substituted by Hydrogen in energetic percents of 6.76%, 13.39%, and 20.97%, the engine power being maintained at the same level comparative to classic fueling. At Hydrogen addition, the diesel fuel jets atomization and diesel fuel droplets vaporization are accelerated, the speed of formation of the mixture being increased. Comparative to classic fueling, the use of Hydrogen leads to diesel droplets combustion intensification, with a shortened autoignition delay, reduction of combustion duration, and increase of flame radius.

Pumpkin Seed Oil

In the current study, the primary components used are pumpkin seed oil biodiesel with diesel was tested in diesel engine and its performance, exhaust emissions, and its effects were observed. The pumpkin seed oil that is used to produce biodiesel undergoes transesterification process along with ethanol, sulphuricacid ,andNaOH catalysts . With blends like B0,B20,B40,B60,B80,and B100, the test on engine performance is obtained, and the reports exposed that, B40 is overlying blend among the other biodiesel blends. In addition, to enhance the performance characteristics of B20,B60,B80 by volume was combined with B40 blend. Due to lower heating characteristics of biodiesel, the observations of BTE for B40 is 4.6% lower than diesel. But the observations of BSFC for B40 is 7.3% higher than diesel. The heat emission rate ofB20,B40,andB60 are almost identical to diesel fuel ,apace with ,at higher loads B40 emitted37.5%less CO and NOx emission was raised at the rate of 95% when correlated to diesel fuel. However, It is observed that there is no major difference not much difference in the emissions (HC, NO, andCO) and characteristics of the engine when using the diesel fuel and Pumpkin seed biodiesel fuel blends

In this study, the performance and emission characteristics were analyzed by using rubber biodiesel in a single cylinder direct injection diesel engine. The experiments were conducted using different combination of fuels such as 20%, 50% of biodiesel blends by volume (B20 and B50) with pure diesel fuel, pure biodiesel (B100) and pure diesel fuel (B0). The performance parameters were obtained for different load conditions from No load to Full load at rated rpm. Results indicated that the higher brake thermal efficiency, Mechanical efficiency, reduced specific fuel consumption obtained for biodiesel blend of B20, compared to other blends and diesel fuel.
