Book excerpt: This thesis was about simulation analysis on 4 stroke single cylinder engine by 1-Dimensional software. Objective of this thesis is to investigate the effect of NOx emission when hydrogen addition is added to the engine and relation between hydrogen addition and cylinder temperatures. Through these objectives, result of the project can obtain by using 1-Dimensional analysis software. GT-Power software is 1-Dimensional analysis software used in this project. GT-Power was used to develop a baseline design engine in order to do a simulation for 4 stroke single cylinder engine.Air-fuel ratios for hydrogen-gasoline mixture are calculated to get the stoichiometric for mixture. In this thesis, air-fuel ratio is used as parameters in GT-Power software. Default parameter in the GT-Power software was used as an engine parameter in this thesis. The ratio of hydrogen-gasoline fuel also must be change at SI-inject which is intake valve in GTPower software. With using default parameter from GT-Power software, a baseline design engine can be developed before run the simulations. After finish the simulation, the results are plotted by using Microsoft Excel. There are many result can be obtained by using GT-Power software but for this simulation, result of NOx emission and temperature are to be consider in this project. These 2 analyses were performed at 3 different engine speeds which are 1000 rpm, 3000 rpm and 5000 rpm, and at 10 until 20 air-fuel ratio. The result shown NOx emissions increased with the increase of hydrogen addition due to the raised cylinder temperature.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis discussed the influence of diesel fuel mixture with hydrogen gas on diesel engine performance in terms of volumetric efficiency, brake efficiency, brake mean effective pressure and brake specific fuel consumption at different engine speed using different mass fraction of hydrogen gas. Engine model drawn using GT-Power and the results of the analysis will be displayed using the GT-Post. In this study, addition of hydrogen gas is by adding hydrogen mass fraction in the air mixture so the gas can be burn with diesel fuel. There are two mass fraction of hydrogen use in the analysis, 0.005% and 0.010% for each analysis. Analysis showed that the addition of hydrogen gas obtained show negative impact on engine performance. Engine performance continued to decrease with the addition of more mass fraction of hydrogen gas.

Download or read book Numerical Analysis of Mixture Formation and Combustion in a Hydrogen Direct Injection Internal Combustion Engine written by Udo Gerke and published by Cuvillier Verlag. This book was released on 2008-02-05 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present work investigates the mixture formation and combustion process of a direct-injection (DI) hydrogen internal combustion engine by means of three-dimensional numerical simulation. The study specifies details on the validity of turbulence models, combustion models as well as aspects on the definition of hydrogen-air burning velocities with respect to hydrogen IC engine applications. Results of homogeneous, stratified and multi-injection engine operation covering premixed, partially premixed and non-premixed combustion of hydrogen are presented. Results of the numerical simulations are validated using data of experimental analysis from parallel works, employing a one-cylinder research engine and a research engine with optical access. As a fundamental contribution to combustion modelling of hydrogen IC engines, a new correlation for laminar burning velocities of hydrogen-air mixtures at engine-relevant conditions is derived from measurements of premixed outwards propagating flames conducted in a single-cylinder compression machine. Numerical results of the direct-injection mixture formation give a detailed understanding of the interrelation between injection timing and the degree of mixture homogenisation. A favourable agreement between the computed fuel concentration and results of Planar Laser Induced Fluorescence (PLIF) measurements is reported for various injection timings. Different two-equation turbulence models, a Shear Stress Transport (SST) model and a k-ε model based on Renormalisation Group (RNG) theory as well as a Reynolds Stress Model (RSM) are discussed. The impact of the models on the level of turbulent kinetic energy proves to be of major importance. State-of-the-art turbulent combustion models on the basis of turbulent flame speed closure (TFC) and on the basis of a flame surface density approach, the Extended Coherent Flame Model (ECFM), are examined. The models are adapted to hydrogen internal combustion engines and are interfaced to the established three-dimensional flow field solver ANSYS CFX within the framework of the international research project HyICE. Two different approaches are investigated as input for the laminar burning velocities of hydrogen. Firstly, flame speed data are computed with a kinetic mechanism. Secondly, an existing experimentally derived laminar flame speed correlation is extended to rich air/fuel equivalence ratios (λ 1) and is compared to measurements conducted within the present work. In general, the TFC-models show a satisfying agreement for DI operating points compared to experimental data, when mixing computations are conducted with the SST turbulence model. Also, port fuel injection (PFI) operating points demonstrate a good performance with these models, however, the constant model prefactor (multiplier for the closure of turbulent flame speed) has to be defined individually for PFI and DI computations. This effect might be caused by the dissimilar sources of turbulence for the two engine types (PFI and DI) which cannot be adequately predicted by the turbulence models. Combustion computations on the basis of mixture results obtained by the RNG-model generally underrate the level of turbulence intensity for stratified operation points, effecting too weak rates of heat release. The ECFM combustion model shows a satisfying predictability for the PFI case using a constant model prefactor. Computations of DI operating points with this model, however, require a readjustment of the prefactor for each operating point in order to match experimental results. Regarding turbulent combustion, the hydrogen laminar flame speed is recognised to be the crucial quantity for the employed modelling approaches. Since direct-injection hydrogen engines in the stratified case engender a wide range of equivalence ratios, fundamental data for the laminar flame speed has to be provided as a model input within the entire boundaries of ignition limits. A lack of experimental data of laminar flame speed at engine-relevant conditions (high pressure, high temperature) is noticed. In order to perform a detailed study on hydrogen burning velocities, a single-cylinder compression machine is selected to conduct flame speed measurements of hydrogen-air mixtures at ignition temperatures and pressures up to T = 700 K and p = 45 bar, considering air/fuel equivalence ratios between λ = 0.4 and 2.8. Flame front velocities are acquired by means of optical methods using OH-chemiluminescence and thermodynamic, multi-zone evaluation of pressure traces. In comparison to data of laminar flame speed derived from reaction mechanisms and flame speed correlations found in literature, the experimental results show increased burning velocities due to flame front wrinkling caused by hydrodynamic and thermo-diffusive instabilities. a href="http://ec.europa.eu/research/transport/news/article_5199_en.html" EU Transport Research
