Book Description
Direct injection (DI) diesel engine is well design today as a main power train solution for trucks and others relevant heavy duty vehicles. However, at the same time emission legislation, mainly for oxides of nitrogens (NOx) and particulate matter (PM) becomes more obvious, reducing their limit to extremely low values. One efficient method to control NOx in order to achieve the future emission limit are the rather high exhaust gas recirculation (EGR) rates accompanied by increased boost pressure to avoid the negative impact on soot emissions. EGR is one of the most effective means of reducing NOx emissions from compression ignition (CI) engines and is widely used in order to meet the emission standards. In the present work, experimental investigation has been carried out to make an analysis the NOx reduction characteristics and the effect to the engine performance by using exhaust gas recirculation between two different fueled engine using biodiesel (palm oil methyl ester B5) and light diesel. This experiment was carried out using a four-cylinder DI diesel engine Mitsubishi 4D68. The purpose of this experiment was conducted is to know the effect of EGR on diesel engine performance and the quantity of NOx emissions in diesel engine's exhaust. The performance of the diesel engine and the quantity of NOx emissions in exhaust gas with using EGR in this experiment will be compared with the performance of the engine and the quantity of NOx emissions in the exhaust gas which not using EGR during the experiment. The results obtained by experiments showing that the EGR has caused the engine performance decreased as compared with no use of EGR. EGR is the best solution for reduced the production of NOx in the exhaust.

Book Description
India, being second largely populated country in the world and 70% of its population depends on agriculture as their main job. Stationary CI engines find wide applications in agricultural area for pumping water, power generation and other crop processing works. Even though emission regulations for such engine applications do not come under stringent norms, their contribution cannot be overlooked. NOx(Oxides of Nitrogen) is considered as one of the most objectionable pollutant from diesel engine. Exhaust Gas Recirculation (EGR), has long been of interest to engine designers, researchers, and regulating authorities in abating NOx. Implementation of EGR for naturally aspirated stationary diesel engines are relatively simple and a study of the application of high level EGR on such an engine is carried to study its impact on the other performance parameters. The results of this investigation give insight into the effect of EGR level on the development of gaseous emissions as well as mechanisms of its formation. Reductions in NOx amount are found to be remarkable with EGR but combustion quality deteriorates at higher loads and higher percentages of EGR due to a significant decrease of A/F ratio. EGR up to 60% is found optimum with 190 bar injection pressure without sacrificing thermal efficiency and increase in unburned HC significantly.

Book Description
Internal combustion engines still have a potential for substantial improvements, particularly with regard to fuel efficiency and environmental compatibility. These goals can be achieved with help of control systems. Modeling and Control of Internal Combustion Engines (ICE) addresses these issues by offering an introduction to cost-effective model-based control system design for ICE. The primary emphasis is put on the ICE and its auxiliary devices. Mathematical models for these processes are developed in the text and selected feedforward and feedback control problems are discussed. The appendix contains a summary of the most important controller analysis and design methods, and a case study that analyzes a simplified idle-speed control problem. The book is written for students interested in the design of classical and novel ICE control systems.
