Book excerpt: Based on the simulations developed in research groups over the past years, Introduction to Quasi-dimensional Simulation of Spark Ignition Engines provides a compilation of the main ingredients necessary to build up a quasi-dimensional computer simulation scheme. Quasi-dimensional computer simulation of spark ignition engines is a powerful but affordable tool which obtains realistic estimations of a wide variety of variables for a simulated engine keeping insight the basic physical and chemical processes involved in the real evolution of an automotive engine. With low computational costs, it can optimize the design and operation of spark ignition engines as well as it allows to analyze cycle-to-cycle fluctuations. Including details about the structure of a complete simulation scheme, information about what kind of information can be obtained, and comparisons of the simulation results with experiments, Introduction to Quasi-dimensional Simulation of Spark Ignition Engines offers a thorough guide of this technique. Advanced undergraduates and postgraduates as well as researchers in government and industry in all areas related to applied physics and mechanical and automotive engineering can apply these tools to simulate cyclic variability, potentially leading to new design and control alternatives for lowering emissions and expanding the actual operation limits of spark ignition engines

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The second law analysis is a powerful tool for assessing the performance of engines and has been employed for few decades now. Turbocharged diesel engines have been explored in much detail with the help of second law analyses. There is also a need to examine the turbocharged spark-ignition engines in greater detail using second law analyses as they are gaining popularity in high performance and conventional automobiles as well. A thermodynamic simulation was developed in order to investigate the effects of turbocharging on spark-ignition engines from second law perspective. The exergy values associated with the components of the turbocharger along with the engine components were quantified as a percentage of fuel exergy. The exergy balance values indicated that turbocharger does not add considerably to the overall irreversibilities and combustion irreversibility is still the major source of exergy destruction. A comprehensive parametric investigation was also performed to investigate the effects of compression ratio, intercooler effectiveness, etc. for the turbocharged spark-ignition engine over the entire load and speed range. The simulation studies helped in understanding the behavior of turbocharged spark-ignition engine with these parameters. A simulation study was also performed to compare the turbocharged engine with the naturally aspirated spark-ignition engine. This study examined the engines for operating parameters like bmep and bsfc over the entire speed range and revealed that turbocharging offers higher bmep and lower bsfc values for most of the operating range. In an additional study, these engines were analyzed for the brake thermal efficiency values at part load. The results indicated that turbocharging offers marginally higher brake thermal efficiency at part loads.

This book was released on 2023-02-22 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a step-by-step guide to the engine control system design, providing case studies and a thorough analysis of the modeling process using machine learning, and model predictive control (MPC). Covering advanced processes alongside the theoretical foundation, MPC enables engineers to improve performance in both hybrid and non-hybrid vehicles. Control system improvement is one of the major priorities for engineers seeking to enhance an engine. Often possible on a low budget, substantial improvements can be made by applying cutting-edge methods, such as artificial intelligence when modeling engine control system designs and using MPC. This book presents approaches to control system improvement at mid, low, and high levels of control. Beginning with the model-in-the-loop hierarchical control design of ported fuel injection SI engines, this book focuses on optimal control of both transient and steady state and also discusses hardware-in-the-loop. The chapter on low-level control discusses adaptive MPC and adaptive variable functioning, as well as designing a fuel injection feed-forward controller. At mid-level control, engine calibration maps are discussed, with consideration of constraints such as limits on pollutant emissions. Finally, the high-level control methodology is discussed in detail in relation to transient torque control of SI engines. This comprehensive yet clear guide to control system improvement is an essential read for any engineer working in automotive engineering and engine control system design.

Available in PDF, EPUB and Kindle. Book excerpt: In view of the ever-increasing consumption of non-renewable vehicular fuels, it is imperative to continually improve the efficiency of Spark-Ignition (SI) engines, which power majority of the light duty vehicles in the US. Increasing the compression ratio is a well-established approach for developing fuel-efficient SI engines. However, the potential benefits of this approach are limited by engine knock, which is driven by the temperature-dependent chemical kinetics of combustion. In combination with the energy released from combustion, in-cylinder heat transfer dictates the magnitude of in-cylinder gas temperatures, thus defining the efficiency and performance of an SI engine. One-dimensional (1D) simulation tools are extensively used in the automotive industry to predict engine performance. In-cylinder heat transfer is calculated within such codes using empirical correlations originally formulated to compute the heat transfer coefficient for turbulent flow within pipes. The turbulent flow field within the combustion chamber interacts with the propagating flame front (during combustion). Consequently, the resulting flow physics is significantly more involved compared to turbulent flow within pipes. Applying a pipe-flow based correlation to estimate in-cylinder heat transfer misrepresents the actual physics, resulting in unreliable heat transfer predictions. Hence, the objective of this work is to address this deficiency by developing a fundamental 1D engine heat transfer model, which is well-grounded in the governing flow physics.

Download or read book Modeling of Turbocharged Spark Ignited Engine and Model Predictive Control of Hybrid Turbocharger written by Kang Rong and published by . This book was released on 2014 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea of a hybrid turbocharger is demonstrated in this thesis. First a battery model and a turbocharged spark ignited(SI) engine is modeled using Simulink. The hybrid turbocharger is obtained by replacing the turbo shaft with a battery, which is connected to the turbine through a generator and to the compressor through a motor. The main idea of the hybrid turbocharger is that the compressor is driven by the battery and the battery is charged by the generator, which is driven by the turbine. Comparisons of the performance of the hybrid turbocharger to the conventional turbocharger and the naturally aspirated engine has been made in a few aspects. The comparison to the naturally aspirated engine shows that the hybrid turbocharger plays a significant role in engine downsizing. In comparison to the conventional turbocharger, it shows that the hybrid turbocharger eliminates the turbo lag. The last step is applying model predictive control (MPC) to the hybrid turbocharger model to minimize the fuel consumption. This is achieved by controlling two inputs of the system. First is controlling the battery output voltage in order to change the compressor speed and influence the air mass flow into the engine. Second is the control of the open angle of the waste gate in order to improve the turbine efficiency and decrease emissions.
