Effect of Hydroxy Gas Injection on Biodiesel Blends from Industrial Palm Oil Residues in Stationary Engines

The use of biodiesel as an alternative fuels in the diesel engine is very effective due to less of emissions and high performance. This study investigated the effect of palm oil blending and engine speed on performance and emission in diesel engine. The performance of biodiesel blends were investigated in terms of brake power, fuel consumption rate, flywheel torque, while emissions parameter was tested in terms of smoke opacity, hydrocarbon (HC), nitrogen oxide (NOx), carbon oxide (CO), carbon dioxide (CO2) and oxygen (O2) at various engine speed 1500, 2000, 2500 and 3000 revolution per minute (rpm). Biodiesel was blended with ordinary diesel fuel in various proportions. The engine was tested up to 50% load conditions by using Ordinary Diesel (OD), B5, B10 and B15 fuels. The properties of biodiesel fuel were tested including density, kinematic viscosity, water content and flash points test. Experimental results indicated that biodiesel blend shows the flywheel torque obtained is higher compared to the OD but fuel consumption rate and the brake power are quite similar when tested at ambient temperature. All biodiesel blends released good emissions compared to the OD. The CO2, CO, HC and O2 content released from the biodiesel fuels were clearly lower than the normal fuel except for NOX contents. Biodiesel released higher smoke opacity compared to OD at all range of engine speeds under 50% load condition. In conclusion, biodiesel fuels are found to offer better performances and emissions and are suitable to be used in unmodified diesel engine.

Crude palm oil (CPO) is one of the vegetable oil that has potential for use as a fuel in diesel engine. Despite years of improvement attempts, the high viscosity and the major chemically bound oxygen component in the biodiesel fuel play as a key element during combustion process. Purpose of this study is to explore how significant the effect of preheated biodiesel blends on the engine performance and emission. The blending of biodiesel was varied from 5vol%(B5)~ 45vol%(B45) and preheated fuel temperature from 40°C~60°C. The engine speed was varied from 1500 rpm~3000 rpm and the load test conditions of 100% are considered. The performances parameter study of diesel engine in brake power, torque and flywheel torque are described together with the emissions parameter such as opacity, hydrocarbon (HC), nitrogen oxide (NOx), carbon oxide (CO), carbon dioxide (CO2) and oxygen (O2). Under high load condition, preheated biodiesel blends were found enhancing the combustion process, resulting in better performances. Increased preheated fuel temperature, higher in torque value and brake power increases significantly as the engine speed increases.

The diesel fuel is most extensively used fossil fuel in automotives and a single major source of hazardous environment pollutant across the globe. As of late, the exploration thinks about distinguished that plant based biodiesel are turning into a promising option sustainable fuel and the consumable/non-eatable oils and creature fats can be utilized feed-stock in arrangement of biodiesel, in light of the fact that its chemical properties practically like fossil diesel fuel, non-poisonous, clean consuming and inexhaustible source. In this work, the performance analysis and emission characteristics of single cylinder, 4-stroke, and water cooled diesel engine was carried-out using Palm oil methyl ester as biodiesel alternative to diesel fuel. Experimental tests have been conducted with range of engine loads using palm oil methyl ester (PME) and its diesel blends with biodiesel in the ratio of 10:90 (B10), 20:80 (B20), and 30:70 (B30), 40:60 (B40), PME 100% (B100) and petro-diesel 100% by volume with and without antimony tin oxide (ATO) additive. In this research work brake power (BP), brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), fuel consumption (FC) are considered as engine performance characteristics and carbon monox ide (CO), hydro carbons (HC), oxides of nitrogen (NOx) are considered as emission characteristics. The experimental results revealed that B10 blend of biodiesel has comparable brake thermal efficiency as diesel. B10 has lowest and B100 has highest BSFC, FC among all the biodiesel blends and biodiesel has lower CO emission, lower HC emission and moderately higher NOx emission when compared with diesel. B10 has shown comparable performance as diesel and it can be considered as alternative to diesel fuel.

Palm Oil Biodiesel

This paper presents the combustion and emissions characteristics including volatile organic compound (VOC) of a common rail direct injection diesel engine fueled with palm oil biodiesel blends contained 0%, 10%, 30%, and 100% (by volume) biodiesel at low idle speed, i.e., 750 rpm. The nitrogen oxide (NOx) emissions of biodiesel blends were lower than that of pure diesel and NOx tended to decrease as the blending ratio increased. Soot opacity and hydrocarbon (HC) were reduced with an increasing blend ratio. Carbon monoxide (CO) varied with the engine load conditions. Under low load, CO emissions tended to decrease with increasing blending ratio and increased under high load. Alkane and aromatic VOCs were mostly emitted. Benzene and tetrahydrofuran accounted for the largest percentage of total detected VOCs in all test conditions. Benzene, toluene, ethylbenzene, xylene (BTEX, toxic aromatic VOCs) were detected for all tests. Among BTEX, benzene has the highest emission ratio, followed by xylene, toluene, and ethylbenzene. Benzene increased for all tests. At low engine load, toluene, ethylbenzene, and xylene decreased with increasing blend ratio. However, these increased at high engine load. When pure palm oil biodiesel was applied at high engine load, benzene decreased.

Palm Oil Biodiesel

This study examined the use of waste plastic oil (WPO) combined with biodiesel as an alternative fuel for diesel engines, also commonly known as compression ignition engines, and focused on comparison of the basic physical and chemical properties of fuels, engine performance, combustion characteristics, and exhaust emissions. A preliminary study was conducted to determine the suitable ratio for the fuel blends in consideration of fuel lubricity and viscosity, and these results indicated that 10% biodiesel—derived from either palm oil or castor oil—in waste plastic oil was optimal. In addition, characterization of the basic properties of these fuel blends revealed that they had higher density and specific gravity and a lower flash point than diesel fuel, while the fuel heating value, viscosity, and cetane index were similar. The fuel blends, comprised of waste plastic oil with either 10% palm oil biodiesel (WPOP10) or 10% castor oil biodiesel (WPOC10), were selected for further investigation in engine tests in which diesel fuel and waste plastic oil were also included as baseline fuels. The experimental results of the performance of the engine showed that the combustion of WPO was similar to diesel fuel for all the tested engine loads and the addition of castor oil as compared to palm oil biodiesel caused a delay in the start of the combustion. Both biodiesel blends slightly improved brake thermal efficiency and smoke emissions with respect to diesel fuel. The addition of biodiesel to WPO tended to reduce the levels of hydrocarbon- and oxide-containing nitrogen emissions. One drawback of adding biodiesel to WPO was increased carbon monoxide and smoke. Comparing the two biodiesels used in the study, the presence of castor oil in waste plastic oil showed lower carbon monoxide and smoke emissions without penalty in terms of increased levels of hydrocarbon- and oxide-containing nitrogen emissions when the engine was operated at high load.
