Book Synopsis Development of a Partially Premixed Combustion Model for a Diesel Engine Using Multiple Injection Strategies by : Rene Thygesen
Download or read book Development of a Partially Premixed Combustion Model for a Diesel Engine Using Multiple Injection Strategies written by Rene Thygesen and published by Logos Verlag Berlin GmbH. This book was released on 2012 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to fulfil future emissions legislations, new combustion systems are to be investigated. One way of improving exhaust emissions is the application of multiple injection strategies and conventional or partially premixed combustion conditions to a Diesel engine. The application of numerical techniques as CFD supports and improves the quality of engine developments. Unfortunately, current spray and combustion models are not accurate enough to simulate multiple injection systems, being in this way a topic of research. The goal of this study was the development of a novel simulation method for the investigation of Diesel engines operated with multiple injection strategies and different combustion modes. The first part of this work focused in improving the spray modelling. The inform ation of 3D CFD simulations of the injector nozzle was introduced in the spray simulation as boundary conditions developing coupling subroutines for this issue. The atomisation modelling was also improved using validated presumed droplet size distributions. Moreover, to avoid the simulation of the injector nozzle for every investigated operating point, a novel interpolating tool was developed in order to create spray boundary conditions based on few 3D CFD simulations of the nozzle under certain initial and boundary conditions. The second part of this thesis dealt with the combustion modelling of Diesel engines. For this issue, a laminar flamelet approach called Representative Interactive Flamelet model (RIF) was selected and implemented. Afterwards, an extended combustion model based on RIF was developed in order to take into account multiple injection strategies. Finally, this new model was validated with a wide range of operating points: applying multiple injection strategies under conventional and partially premixed combustion conditions.
Book Synopsis Modelling Diesel Combustion by : P. A. Lakshminarayanan
Download or read book Modelling Diesel Combustion written by P. A. Lakshminarayanan and published by Springer Nature. This book was released on 2022-01-21 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book comprehensively discusses diesel combustion phenomena like ignition delay, fuel-air mixing, rate of heat release, and emissions of smoke, particulate and nitric oxide. It enables quantitative evaluation of these important phenomena and parameters. Most importantly, it attempts to model them with constants that are independent of engine types and hence they could be applied by the engineers and researchers for a general engine. This book emphasizes the importance of the spray at the wall in precisely describing the heat release and emissions for most of the engines on and off-road. It gives models for heat release and emissions. Every model is thoroughly validated by detailed experiments using a broad range of engines. The book describes an elegant quasi-one-dimensional model for heat release in diesel engines with single as well as multiple injections. The book describes how the two aspects, namely, fuel injection rate and the diameter of the combustion bowl in the piston, have enabled meeting advanced emission, noise, and performance standards. The book also discusses the topics of computational fluid dynamics encompassing RANS and LES models of turbulence. Given the contents, this book will be useful for students, researchers and professionals working in the area of vehicle engineering and engine technology. This book will also be a good professional book for practising engineers in the field of combustion engines and automotive engineering.
Book Synopsis Investigation of RCCI Operation with Customized Pistons in a Light-duty Multi-cylinder Engine Using Dieseline by :
Download or read book Investigation of RCCI Operation with Customized Pistons in a Light-duty Multi-cylinder Engine Using Dieseline written by and published by . This book was released on 2016 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an attempt to increase efficiency and lower critical and highly regulated emissions (i.e., NOx, PM and CO2) many advanced combustion strategies have been investigated. Most of the current strategies fall into the category of low temperature combustion (LTC), which allow emissions mandates to be met in-cylinder along with anticipated reduction in cost and complexity. These strategies, such as homogeneous charge compression ignition (HCCI), premixed charge compression ignition (PCCI), partially premixed combustion (PPC) and reactivity controlled compression ignition (RCCI), use early injection timings, resulting in a highly lean charge with increased specific heat ratios to improve thermal efficiency and reduce PM emissions. Lower combustion temperatures also avoid the activation of NOx formation reactions. However, the lean air/fuel ratio decreases fuel oxidation rates of CO and HC and, due to longer ignition delays with high peak pressure rise rate (PPRR) and heat release rates (HRR), confines the engine’s operating loads and speeds. A strategy to reduce these negative effects of LTC is RCCI, which generally uses two fuels with different reactivities in order to optimize ignitability and equivalence ratio stratification. It has demonstrated improvements in efficiency and low NOx and PM emissions by utilizing in-cylinder fuel blending, while the simultaneous optimization of fuel reactivity results in increased engine operating space. The current work investigates Reactivity Controlled Compression Ignition (RCCI) combustion in a light-duty multi-cylinder engine over steady-state and transient operating conditions using also fast exhaust sampling emissions equipment for UHC, NO and PM measurements. A “single-fuel ” approach for RCCI combustion was studied using port-injected and direct-injected (DI) cetane improved gasoline with custom designed, 15.3:1 compression ratio, pistons. In addition, experiments were conducted using mixtures of gasoline and diesel, i.e., “dieseline”, as the high reactivity fuel. The experiments were performed over a broad selection of “ad hoc” load and speed points in order to examine performance and emission effects of a less reactive DI fuel mixture to in turn reduce the need for a second fuel. This work also helps to demonstrate the requirements for high levels of boost in a multi-cylinder engine during RCCI operation. Comparisons were also made to an HCCI/GCI like combustion strategy using similar gasoline/diesel fuel blends.

Available in PDF, EPUB and Kindle. Book excerpt: The diesel engine is one of the most efficient types of heat engines and is widely used as a prime mover for many applications. In recent years, with the aid of modern computers, engine combustion modeling has made great progress. However, due to the complexities of the processes involved in the practical diesel engine, there are still too many unknowns preventing computational prediction to have the accuracy level required by industry. This book examines some basic characteristics of diesel engine combustion process, and describes the commonly used tool to analyze combustion - heat release analysis. It addition, Practical Diesel-Engine Combustion Analysis describes the performance changes that might be encountered in the engine user environment, with a goal of helping the reader analyze his own practical combustion problems. Chapters include: Combustion and Fuel-Injection Processes in the Diesel Engine Heat Release and its Effect on Engine Performance Alternate Fuels Combustion Analysis and more
