This book was released on 2013-04-17 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the second book edited with a selection of papers from the two-yearly THIESEL Conference on Thermo- and Fluid Dynamic Processes in Diesel Engines, organised by CMT-Mvtores Termicos of the Universidad Po/itecnica de Valencia, Spain. This volume includes versions of papers selected from those presented at the THIESEL 2002 Conference th held on lOth to 13 September 2002. We hope it will be the second volume of a long series reflecting the quality of the THIESEL Conference. This year, the papers are grouped in six main thematic areas: State of the Art and Prospective, Injection Systems and Spray Formation, Combustion and Emissions, Engine Modelling, Alternative Combustion Concepts and Experimental Techniques. The actual conference covered a wider scope of topics, including Air Management and Fuels for Diesel Engines and a couple of papers included reflect this variety. However, the selection of papers published here represents the most current preoccupations of Diesel engine designers, namely how to improve the combustion process using new injection strategies and alternative concepts such as the Homogeneous Charge Combustion Ignition.

This book was released on 2011-06-22 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computational Optimization of Internal Combustion Engines presents the state of the art of computational models and optimization methods for internal combustion engine development using multi-dimensional computational fluid dynamics (CFD) tools and genetic algorithms. Strategies to reduce computational cost and mesh dependency are discussed, as well as regression analysis methods. Several case studies are presented in a section devoted to applications, including assessments of: spark-ignition engines, dual-fuel engines, heavy duty and light duty diesel engines. Through regression analysis, optimization results are used to explain complex interactions between engine design parameters, such as nozzle design, injection timing, swirl, exhaust gas recirculation, bore size, and piston bowl shape. Computational Optimization of Internal Combustion Engines demonstrates that the current multi-dimensional CFD tools are mature enough for practical development of internal combustion engines. It is written for researchers and designers in mechanical engineering and the automotive industry.

Book excerpt: Volume 2 of the two-volume set Advanced direct injection combustion engine technologies and development investigates diesel DI combustion engines, which despite their commercial success are facing ever more stringent emission legislation worldwide. Direct injection diesel engines are generally more efficient and cleaner than indirect injection engines and as fuel prices continue to rise DI engines are expected to gain in popularity for automotive applications. Two exclusive sections examine light-duty and heavy-duty diesel engines. Fuel injection systems and after treatment systems for DI diesel engines are discussed. The final section addresses exhaust emission control strategies, including combustion diagnostics and modelling, drawing on reputable diesel combustion system research and development. - Investigates how HSDI and DI engines can meet ever more stringent emission legislation - Examines technologies for both light-duty and heavy-duty diesel engines - Discusses exhaust emission control strategies, combustion diagnostics and modelling
Book Synopsis A Quasi-dimensional Charge Motion and Turbulence Model for Combustion and Emissions Prediction in Diesel Engines with a fully Variable Valve Train by : Qirui Yang
Download or read book A Quasi-dimensional Charge Motion and Turbulence Model for Combustion and Emissions Prediction in Diesel Engines with a fully Variable Valve Train written by Qirui Yang and published by Springer Nature. This book was released on 2021-10-01 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Qirui Yang develops a model chain for the simulation of combustion and emissions of diesel engine with fully variable valve train (VVT) based on extensive 3D-CFD simulations, and experimental measurements on the engine test bench. The focus of the work is the development of a quasi-dimensional (QDM) flow model, which sets up a series of sub-models to describe phenomenologically the swirl, squish and axial charge motions as well as the shear-related turbulence production and dissipation. The QDM flow model is coupled with a QDM combustion model and a nitrogen oxides (NOx) / soot emission model. With the established model chain, VVT operating strategies of diesel engine can be developed and optimized as part of the simulation for specific engine performance parameters and the lowest NOx and soot emissions.

Download or read book COMBUSTION, EMISSIONS, AND PERFORMANCE OPTIMIZATION IN A DI/PFI-RCCI DIESEL/NATURAL GAS TURBOCHARGED ENGINE written by and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Diesel-NG fuel blends are increasingly being used in Reactivity Controlled Compression Ignition (RCCI) applications due to high Brake Thermal Efficiency (BTE), low NOx and PM emissions. But it also has a few disadvantages such as high HC and CO emission and relatively low Exhaust Gas Temperature (EGT). This leads to find out the optimum tradeoff between emissions to meet the regulation and also investigate the cost of operation and find out the minimum liquid consumption (fuel + urea) in RCCI mode. A Cost Function (CF) including Brake Specific Fuel Consumption (BSFC) and Brake Specific Urea Consumption (BSUC) is considered and minimized in this study. This optimization helped to investigate the optimum input parameters between 3 to 12 bar IMEP at 1500 RPM engine speed. This study has been done while all the population in optimization process meet the Tier 3 Bin 20 emission regulations. To increase the number of data points in this optimization, a mathematical (numerical) model is developed to predict (or assess) the Diesel-NG RCCI data. Single fuel diesel only mode is also considered in this optimization, since high BTE of RCCI is limited to medium and high load operating conditions and due to the high HC and low EGT, RCCI may not be an ideal combustion mode at low loads. Parametric models have been developed and validated using experimental data on a light duty 1.9L inline 4 cylinder Compression Ignition (CI) engine as a function of independent input variables including, first and second Start of Injection (SOI1 and SOI2), Manifold Absolute Pressure (MAP), lambda, Exhaust Gas Recirculation (EGR) and Blending Ratio (BR), and validated using RCCI experimental data. In these models, selected emissions - including HC, CO, PM and NOx-, Exhaust Gas Temperature (EGT) and BSFC were computed using correlations as functions of independent input variables. The computed EGT were then used to estimate the Selective Catalyst Reduction (SCR) and Diesel Oxidation Catalyst (DOC) efficiencies to assess the emission data for different input variables by considering after-treatment system to see if they meet the tailpipe emission regulation. Running the engine with this calibrated input parameters not only meet the Tier 3 Bin 20 EPA standard, but also minimized the cost of operation in RCCI mode within 3 to 12 bar IMEP engine load at 1500 RPM engine speed.
