Combustion engines have long been the heart of transportation, powering vehicles with a blend of precision and power. The development of combustion engines has seen remarkable advancements in areas such as mixture formation, combustion emissions, and simulation techniques. In this book, we delve into the intricacies of these crucial aspects, shedding light on the evolution of combustion engines.
Mixture Formation: The Fuel for Power
Mixture formation plays a pivotal role in the efficient functioning of combustion engines. It involves the precise mixing of fuel and air in the combustion chamber, creating the ideal blend for combustion. Through innovations in fuel injection systems and intake technologies, engineers have optimized mixture formation to enhance engine performance and fuel efficiency.
Combustion Emissions: Balancing Power and Environmental Impact
While combustion engines provide the necessary power for vehicles, they also produce emissions that impact the environment. The quest for cleaner combustion emissions has led to the development of catalytic converters, exhaust gas recirculation systems, and other technologies aimed at reducing harmful pollutants. By striking a balance between power output and emissions control, engineers strive to create more environmentally friendly combustion engines.
Simulation: Modeling the Future of Combustion Engines
Simulation plays a crucial role in the development of combustion engines, allowing engineers to visualize and optimize engine performance virtually. Through advanced computer-aided design (CAD) and computational fluid dynamics (CFD) simulations, researchers can test different combustion scenarios, analyze airflow patterns, and fine-tune engine parameters without the need for physical prototypes. This virtual testing environment accelerates the engine development process and enables engineers to iterate rapidly toward more efficient and powerful designs.
The evolution of combustion engines in the realms of mixture formation, combustion emissions, and simulation represents a continuous quest for innovation and improvement. By harnessing the power of technology and engineering expertise, researchers are paving the way for the next generation of combustion engines that are not only powerful and efficient but also environmentally conscious. As we look towards the future, the journey of combustion engine development promises to unlock new possibilities and propel us towards a greener and more sustainable tomorrow.
About the Book
Today, commercial computer programs are usually used for the development of engines and vehicles, for example, for simulation of the transient performance of a vehicle or a complete power train, as well as for simulation of high-grade transient processes in the engine combustion chamber.
In general, the source code of these computer programs is not available, and due to the time-consuming study of the corresponding descriptions, users often have insufficient knowledge of the physical and chemical content of the models used in these programs. It is therefore our special concern to reveal the different physical and chemical approaches and to show the choice and limits of the models used. Therefore, the focus of the book is undoubtedly on the thermodynamic, fluid-mechanical, and chemical basis of the modeling of motor-driven processes.
The book consists of 3 parts. The first part describes the operation and thermodynamic basis of the combustion engine, combustion and kinetics, and the construction of emissions in six chapters. This chapter is completed by procedures related to combustion measurement. Chaps and Part II. 7-9 is dedicated to the operating process calculation, charging process, and modeling of exhaust after-treatment system. Part III includes Chaps. Starting from 10-15 and the overall process analysis. Part III gives priority to the possibility of calculating combustion engines, such as phenomenological combustion models, injection and combustion simulations, and 3D simulations of fluid flow and supercharging.
We hope that we have succeeded in showing a comprehensive and current description of the simulation of the motor drive process, and we hope that all academic and technical users can benefit from this book.
