    Based on the changes of catalyst properties, a model was constructed to estimate the rate constants of Standard-SCR, NH3 oxidation, and NO oxidation reactions over hydrothermally aged Cu-CHA catalyst. Moreover, the rate constants obtained by the constructed model were applied to the model for estimating NOx conversion over fresh catalyst constructed in previous studies, and the NOx conversion over hydrothermally aged catalyst was estimated. As a result, the calculated NOx conversion over hydrothermally aged Cu-CHA catalyst was in good agreement with the experimental results.

    To develop a high-performance three-way catalyst, it is necessary to construct an accurate catalytic reaction model. Previously, we have developed the three-way catalyst model under dry simulated exhaust gas conditions. Water, which is contained in the real exhaust gas, however, complicate the phenomenon encountered in the three-way catalyst. Thus, in this study, the effect of water on the catalytic reaction on a palladium-based three-way catalyst was investigated. Moreover, a catalytic reaction model was developed based on the experimental results. As a results, it is found that the constructed model well predicted the light-off behavior of the palladium-based three-way catalyst.

  • 実機相当雰囲気におけるOME-軽油混合燃料の噴霧および燃焼特性
    佐々木 旺雅; 樋熊 航; 境田 悟志; 田中 光太郎; 金野 満; 瀬戸 雄史; 石川 直也,

    The fuel generated from CO2 and H2 derived from renewable energy is called "e-fuel". Among the e-fuels, polyoxymethylene dimethyl ether (OME) is expected as a promising drop-in fuel for CI engines because it has good ignitability and low-soot combustion characteristics. However, the fuel properties such as density, heating value, and stoichiometric air-fuel ratio are different from those of diesel fuel. In this study, the spray and combustion characteristics of OME-diesel blends fuel were investigated and compared with diesel spray under engine-relevant condition at 920K-6.0MPa in a constant volume vessel. First, the fuel sprays were observed using high speed cameras under the non-reacting condition with O2 concentration of 0%. The result showed that spray-tip penetration length of OME-diesel blends was almost the same as diesel fuel, irrespective of the OME blend ratios, while the spray cone angle and spray projected area increased as the OME blend ratio increased. Moreover, the liquid phase length and width of OME spray were smaller than diesel spray. Then the reacting sprays were observed under the combustion condition with O2 concentration of 16% to understand combustion characteristics. The result showed that the ignition delay and the flame lift-off length were shortened as the OME blend ratio increased.

  • ガソリンに構造の異なる炭化水素を混合した際の自着火特性の変化

    In this study, the ignition delay time of gasoline blended with various hydrocarbons having different molecular structures (isooctane, n-heptane, 1-pentene, and toluene) was measured using a rapid compression machine. Additionally, the effect of mixing hydrocarbons on the ignition characteristics of gasoline surrogate fuels was investigated. The ignition delay times were measured under two conditions: an equivalence ratio of 0.5 and an equivalence ratio of 1.0 with an EGR ratio of 30%. The compressed pressure and temperature were 4.0 MPa and 750 K, respectively. When toluene was blended with the gasoline surrogate, the ignition delay time increased regardless of the experimental conditions. In contrast, when n-heptane was blended with the gasoline surrogate, the ignition delay time decreased. When isooctane and 1-pentene were individually blended with the gasoline surrogate, the ignition delay times were unchanged with varying mixing ratios. Based on the chemical kinetic analysis, it is found that the reactivity for the low-temperature oxidation of blended fuels changed when each hydrocarbon was blended, which determines the ignition characteristics of blended fuels.

    A temperature measurement method based on laser absorption spectroscopy was developed to obtain the time history of temperatures during the low-temperature oxidation (LTO) of iso-octane. The absorption signals of H2O were measured using two near-infrared distributed feedback laser diodes emitting at wavelengths near 1392 and 1842 nm. The temperature was obtained based on the absorbance ratios between two temperature-dependent absorption lines. The temperature profiles in the LTO of iso-octane at 0.77 MPa, 660 K were successfully obtained. The calculated temperature profiles using the latest chemical kinetic model of iso-octane had the same tendency as the experimental profiles.

    The penetration of DME spray is shorter than that of diesel fuel when the same injection system is used because DME cannot be injected at high pressure like diesel fuel due to its high compressibility. Chris reported that supercritical gasoline spray has a wider spray angle and has increased penetration. Therefore, there is possibility that supercritical DME spray has increased penetration. However, there is no observation on the shape, development process, combustion of supercritical DME spray. In this study, the spray and combustion characteristics of supercritical DME in an optically accessible constant volume vessel were observed under turbo charged engine-like ambient condition. Parallel light shadow graph and diffused light shadow graph method were applied to image the liquid and vapor phase behavior. Moreover, the spray angle of supercritical spray was compared with that of subcritical one under the same ambient condition to confirm the influence of fuel temperature. The results show that there is no significant difference in spray shape between supercritical and subcritical spray under turbo charged engine-like ambient condition.

  • Large scale simulation of liquid water transport in a gas diffusion layer of polymer electrolyte membrane fuel cells using the lattice Boltzmann method
    S. Sakaida; Y. Tabe; and T. Chikahisa, Lead, A method for the large-scale simulation with the lattice Boltzmann method (LBM) is proposed for liquid water movement in a gas diffusion layer (GDL) of polymer electrolyte membrane fuel cells. The LBM is able to analyze two-phase flows in complex structures, however the simulation domain is limited due to heavy computational loads. This study investigates a variety means to reduce computational loads and increase the simulation areas. One is applying an LBM treating two-phases as having the same density, together with keeping numerical stability with large time steps. The applicability of this approach is confirmed by comparing the results with rigorous simulations using actual density. The second is establishing the maximum limit of the Capillary number that maintains flow patterns similar to the precise simulation; this is attempted as the computational load is inversely proportional to the Capillary number. The results show that the Capillary number can be increased to 3.0 x 10(-3), where the actual operation corresponds to Ca =10(-5)similar to 10(-8). The limit is also investigated experimentally using an enlarged scale model satisfying similarity conditions for the flow. Finally, a demonstration is made of the effects of pore uniformity in GDL as an example of a large-scale simulation covering a channel. (C) 2017 Elsevier B.V.

  • Scale Model Experiment of Liquid Water Transport in Gas Diffusion Layer of PEFC and Optimization of the Structure
    S. Sakaida; Y. Tabe; T. Chikahisa, Lead, In a polymer electrolyte fuel cell (PEFC), it is important to control water transport in the cell to supply oxygen smoothly to the reaction zone. Produced water in the catalyst layer transports through microporous layer (MPL), gas diffusion layer (GDL), and then reaches to the channel. All of the layers are important for the water control, and this study focuses on the water transport behavior in the GDL, which has complex fiber structure. For observation of the motion, a scale model experiment was developed using silicon oil and water to keep Capillary number equivalent to the actual cell. The fiber structure of the GDL was fabricated with a 3D printer. With the scale mode, effects of GDL property such as wettability on the water behavior were investigated, and the results were compared to the numerical simulation with Lattice Boltzmann Method., ELECTROCHEMICAL SOC INC

The combustion model for this objective must be able to simulate the engine performance in very short time. We have tried to develop such diesel engine combustion model by adding the improvements to the Hiroyasu model. In this paper, we detail the improvements that were added to this model and comparisons the calculated results by the improved model with experimental result. © Copyright 2011 Society of Automotive Engineers of Japan, Inc. and SAE International.
