Item type:Publication, Injection Characteristics of Palm Methyl Ester Blended with Diesel Using Zuech’s Chamber(2018-06-01); ; Tongroon, ManidaThis research attempts to characterize the injection of palm biodiesel blended with diesel in a Zuech’s chamber. Thailand conventional diesel (mandated blend of biodiesel at 5 % or B5), palm biodiesel (B100) and four other biodiesel blends ratios (B20, B40, B60 and B80) were investigated with single hole injector of 140 and 200 μm diameters, injection pressure of 40 MPa to 160 MPa, constant back pressure of 4.5 MPa and energize time of 2.5 ms. The results show that increasing biodiesel blending ratios leads to longer injection delay, larger injection pressure drop, smaller injection quantity discharge coefficient (C<inf>d</inf>) and shorter injection duration. With increasing biodiesel blending ratio, high Cavitation number from biodiesel viscosity decreases Reynolds number. Increasing injector diameter from 140 μm to 200 μm has reduced injection delay, increased fuel injection quantity, discharge coefficient and remaining injection duration. The increasing of injection pressure were improve, injection delay, injection duration, injection quantity and discharge coefficient until injection pressure 120 MPa. In addition at injection pressure over 120 MPa are decrease injection quantity and discharge coefficient, it effect form the cavitation phenomena. Increasing of viscosity, density, Bulk modulus and sound velocity were effect to increase injection delay, with reduce injection quantity, injection duration and pressure drop during injection process. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Physical characterization of biodiesel particle emission by electron microscopy(2013-01-01); ; Chollacoop, NuwongNanostructures of diesel and biodiesel engine particulate matters (PMs) were investigated by using a Transmission Electron Microscopy (TEM). The average single particle sizes of biodiesel and diesel PMs are approximately 30-40 nm and 50-60 nm, respectively. Image processing process was used to estimate each carbon platelet length by using TEM image. The average carbon platelet length of biodiesel and diesel PMs are in the range of 0.1-7.0 nm. Moreover, carbon atoms per cubic volume of PMs are approximately 500-900. The result shows that engine load and fuel property are strongly impact on the size of single particle and carbon atom density of particle. This is one of interesting behaviors need to be investigated for better understanding. The results of this research would be used as basic information for design and develop removing process of PM emitted from engine combustion which using in diesel and biodiesel fuels. © Copyright @2013 SAE Japan and Copyright @ 2013 SAE International. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Side effect of production of biodiesel from jatropha seed oil: A case study in Thailand(2014-01-01); Srinorakutara, TeerapatrThe objective of this research is to produce biodiesel from the jatropha seed oil and compare its lubricating properties to other types of fuel used in a compression ignition engine. The optimum mixture is also investigated. The produced biodiesel is tested to determine its identity and purity. The result showed that its purity is 98.38%, which is higher than 96.5% as specified by the standard of Department of Energy Business. The resulting biodiesel is tested in a compression ignition engine, including as an additive to stabilize the ethanol in diesel oil. The four types of fuel blends are; diesohol with a proportion of diesel: ethanol: biodiesel D95E5B5 by volume, pure biodiesel from jatropha seed oil, biodiesel with low proportion D95B5, and a standard diesel oil. The test results of physical properties of the four types of fuel show that all meets the standard of high speed diesel oil, except the flash point property of the diesohol. To compare the lubricating properties, each type of the fuel has been tested with the High Frequency Reciprocating Rig (HFRR) according the CEC-F-06-A-96 standard. The results showed that the pure biodiesel from jatropha seed oil, biodiesel D95B5 and diesohol D95E5B5 have the wear scar 169 μm, 204 μm, and 205 μm respectively. The wear scar of each type of the studied fuels is below the allowable standard wear scar 460μm. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Combustion characteristics of hydrotreated vegetable oil – diesel blend under EGR and supercharged conditions(2017-08-01); Sato, SusumuThis paper investigates the effects of Hydrotreated vegetable oil-diesel blend to combustion characteristics under various ambient oxygen concentrations and ambient pressure. Combustion characteristics were investigated using heat release rate analysis, two color method, soot concentration measurement and NOx concentration measurement. The experiments were carried out on a rapid compression expansion machine to simulate the ambient condition of a CI engine at TDC. Synthetic gas with oxygen concentrations of 21 %, 15 % and 10 % were used to simulate EGR conditions. A single hole injector was used with five different fuels: commercial diesel, HVO-commercial diesel blends and HVO. The results showed that increasing HVO blending percentages decreased ignition delay, flame temperature, soot concentration and NOx concentration. Heat release at oxygen concentration of 10 % dramatically dropped due to a shortened ignition delay, which resulted in less combustion. A decreased oxygen concentration from applied EGR conditions not only increased ignition delay, heat release, flame temperature and NO<inf>x</inf> concentration, but also increased soot concentration. A combination of EGR and supercharged conditions by increasing ambient pressure and decreasing oxygen concentrations resulted in increased heat release, decreased flame temperature, ignition delay and soot concentration, compared to EGR conditions. - Some of the metrics are blocked by yourconsent settings
