Available in PDF, EPUB and Kindle. Book excerpt: Phenomenology of Diesel Combustion and Modeling Diesel is the most efficient combustion engine today and it plays an important role in transport of goods and passengers on land and on high seas. The emissions must be controlled as stipulated by the society without sacrificing the legendary fuel economy of the diesel engines. These important drivers caused innovations in diesel engineering like re-entrant combustion chambers in the piston, lower swirl support and high pressure injection, in turn reducing the ignition delay and hence the nitric oxides. The limits on emissions are being continually reduced. The- fore, the required accuracy of the models to predict the emissions and efficiency of the engines is high. The phenomenological combustion models based on physical and chemical description of the processes in the engine are practical to describe diesel engine combustion and to carry out parametric studies. This is because the injection process, which can be relatively well predicted, has the dominant effect on mixture formation and subsequent course of combustion. The need for improving these models by incorporating new developments in engine designs is explained in Chapter 2. With “model based control programs” used in the Electronic Control Units of the engines, phenomenological models are assuming more importance now because the detailed CFD based models are too slow to be handled by the Electronic Control Units. Experimental work is necessary to develop the basic understanding of the pr- esses.
Book Synopsis Performance Simulation and Control Design for Diesel Engine NOx Emission Reduction Technologies by : Hai Wu
Download or read book Performance Simulation and Control Design for Diesel Engine NOx Emission Reduction Technologies written by Hai Wu and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fuel efficiency and emission reductions are the two consistent drivers for internal combustion engine development for both on-highway and off-road vehicles. Advanced combustion technologies are proposed for the improvement of fuel consumption and reduction of harmful gas production inside the cylinder in laboratory engines. Outside cylinder technologies and after-treatment are the alternatives for a production engine to meet the stringent emission standards. Advanced control technologies play important roles in the realization of new technologies. This research was aimed at investigating possible techniques and feasible methods of implementation to reduce diesel engine emissions to meet the more stringent Tier 4 standards. In this study, two technologies are studied for off-road diesel engine NOx emission reductions: stoichiometric combustion ignition (SCI) and lean NOx trap (LNT). The concept of the stoichiometric compression ignition (SCI) engine was investigated for implementation in a turbocharged diesel engine through co-simulation. At first, an integrated environment for 1D engine modeling with control function was proposed for a SCI performance evaluation and control implementation. The SCI engine has been evaluated by Constant Speed Load Acceptance tests under steady-state and transient conditions. For SCI implementations, basic controls have been designed including air-fuel ratio (AFR) control, torque limiting control and idle speed control. The proposed control strategies have been verified with 1D detail models in the integrated environments. Further, the Mean Value Engine Model (MVEM) is proposed for advanced model based control design. The SCI engine subsystems are modeled using an orifice constrain model for throttle, turbine, and wastegate; filling and emptying model for intake and exhaust manifolds; rotational dynamic for engine camshaft and turbocharger shift, air-charging model and exhaust properties regressed by the data from integrated simulation at different engine operating conditions. The MVEM was implemented in Matlab/Simulink for verification. Modular and system verification was conducted for steady-state and transient state consistency with the 1D detail model. The results are promising, but the whole system needs further tuning for dynamic control design. The lean-NOx trap, as an alternative after-treatment for NOx control, has been studied for generic diesel engine emission control. Based on experimental data, an improved NOx adsorption model is proposed for integrated engine control and optimization.
Book Synopsis Machine Learning and Deep Learning for Modeling and Control of Internal Combustion Engines by : Armin Norouzi Yengeje

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Internal Combustion Engines (ICEs) are ubiquitous; they power a wide range of systems. The broad use of ICEs globally causes more than 20% of the total greenhouse gas emissions. In many countries, emission legislation is transitioning from certification using only traditional chassis dynomometer testing to now requiring the inclusion of Real Driving Emissions (RDE). Complying with this legislation has led to increased challenges to meet emissions levels under on-road use of the engine. The stringent legislation governing emissions and fuel economy, in combination with the complexity of the combustion process, have led to requirements for significantly more advanced engine controllers than are currently used. Reducing the emissions of diesel engines while simultaneously increasing their thermal efficiency through online control optimization and Machine Learning (ML) are the main objectives of this thesis. ML techniques offer powerful solutions that help to address the existing challenges in ICE modeling, control, and optimization. ML can also help to reduce the time, cost, and effort required for ICE calibration for both vehicular and stationary applications. In this thesis, a four-cylinder medium-duty Cummins diesel engine and emission measurement system including an electrochemical fast Nitrogen Oxides (NOx) sensor, Pegasor Particle Sensor (PPS-M), and MKS Fourier-Transform Infrared Spectroscopy (FTIR) are used for experimental implementation. A dSPACE MicroAutoBox II, which is a rapid prototyping system, is used for control implementation. In order to compare the proposed control method with the existing Cummins calibrated engine control unit (ECU), all the production calibration tables are imported to the MicroAutoBox. The simulation results presented in this thesis are developed using a detailed physics-based model using the GT-power\(^{\copyright}\) software. A co-simulation of GT-power\(^{\copyright}\)/Matlab\(^{\copyright}\)/Simulink is used as an Engine Simulation Model (ESM). The application of ML in engine control can be divided into three main categories: i) ML in emission prediction, ii) Integration of ML and Model Predictive Control (MPC), and iii) ML in the learning-based controller. In the first category, a correlation-based order reduction algorithm is developed to model \nox, resulting in a simple and accurate model. This algorithm utilizes Support Vector Machine (SVM) techniques to predict \nox~emission with high accuracy. In addition, a comprehensive study involving eight ML methods and five feature sets is done for Particulate Matter (PM) modeling using gray-box techniques. Then using the K-means clustering algorithm, a systematic way to select the best method for a specific application is proposed. In the second category, two methods of combining ML and MPC were used: ML-based modeling and ML imitation control. First, ML is used to identify a model for implementation in MPC optimization problems. Additionally, ML can be used to replace MPC, where the ML controller learns the optimal control action by imitating the behavior of the MPC. Using the ESM to provide simulation data, SVM and deep recurrent neural networks, including long-short-term memory (LSTM) layers, are used to develop engine performance and emission models. Then based on these models, MPC is designed and compared to both a linear controller and the Cummins' calibrated ECU model in ESM. Then, a deep learning scheme is deployed to imitate the behavior of the developed controllers. These imitative controllers behave similarly to the online optimization of MPC but require significantly lower computational time. The LSTM-based MPC is then implemented on the real-time system using open-source software. Compared to the stock Cummins ECU, this controller has significant emission reduction, fuel economy improvement, and thermal efficiency. Reinforcement Learning (RL) and Iterative Learning controller (ILC) are developed to investigate learning-based controllers. Using the ESM, a model-free off-policy algorithm, Deep Deterministic Policy Gradient (DDPG), is developed. A safety filter is added to the deep RL to avoid damage to the engine. This filter guarantees output and input constraints for both RL and ILC. The developed safe RL is then compared with ILC and LSTM-NMPC.
