This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through an experimental study, this work focused on finding the influence of exhaust gas recirculation (EGR) on waste plastic pyrolysis oils (WPPOs) with diesel as a base comparison fuel. The results show the amount of carbon monoxide emissions seemed to decrease at low engine loads up to intermediate loads of (50%), thereafter continued to increase significantly but marginally. Among fuels tested, blend WPPOB100 reported the highest BSFC, at 0% EGR flow rate. The value was 0.4751g/kW.hr. compared with 0.7235 g/kW.hr. at 30% EGR flow rate. Increased blend ratio had a direct decrease in brake power linearly. At 30% engine load, CD, WPPOB10, WPPOB20, WPPOB30 and WPPOB40 recorded values of 2.125 kW, 2.15 kW, 2.05 kW, 1.98 kW, 1.86 kW and 1.75 kW, respectively. Exhaust gas temperature (EGT) at 30% EGR flow rate, blend WPPOB10 had the highest reduction in temperature compared with the any other WPPO blends at 320°C. Increased blend ratio and EGR percentage flow rate increased smoke emissions within the test fuels blends. At 15% EGR flow rate, the following data were recorded: 7.53%, 7.1%, 6.72%, 6.25%, 6.0% and 5.4% for CD, WWPO10, WPPO20, WPPO30, WPPO40 and WPPO100, respectively.

Download or read book Effect of Exhaust Gas Recirculation to Performance and Emissions of Diesel Engine written by Mustaqim Mohamad and published by . This book was released on 2010 with total page 57 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The homogeneous charge, compression-ignition (HCCI) combustion process has the potential to significantly reduce NOx and particulate emissions, while achieving high thermal efficiency and the capability of operating with a wide variety of fuels. This makes the HCCI engine an attractive technology that can ostensibly provide diesel-like fuel efficiency and very low emissions, which may allow emissions compliance to occur without relying on lean aftertreatment systems. A profound increase in the level of research and development of this technology has occurred in the last decade. This book gathers contributions from experts in both industry and academia, providing a basic introduction to the state-of-the-art of HCCI technology, a critical review of current HCCI research and development efforts, and perspective for the future. Chapters cover: Gasoline-Fueled HCCI Engines; Diesel-Fueled HCCI Engines; Alternative Fuels and Fuel Additives for HCCI Engines; HCCI Control and Operating Range Extension; Kinetics of HCCI Combustion; HCCI Engine Modeling Approaches.In addition to the extensive overview of terminology, physical processes, and future needs, each chapter also features select SAE papers (a total of 41 are included in the book), as well as a comprehensive list of references related to the subjects. Homogeneous Charge Compression Ignition (HCCI) Engines: Key Research and Development Issues provides a valuable base of information for those interested in learning about this rapidly-progressing technology which has the potential to enhance fuel economy and reduce emissions.
Download or read book Diesel Engine Transient Operation written by Constantine D. Rakopoulos and published by Springer Science & Business Media. This book was released on 2009-03-10 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, the study of internal combustion engines operation has focused on the steady-state performance. However, the daily driving schedule of automotive and truck engines is inherently related to unsteady conditions. In fact, only a very small portion of a vehicle’s operating pattern is true steady-state, e. g. , when cruising on a motorway. Moreover, the most critical conditions encountered by industrial or marine engines are met during transients too. Unfortunately, the transient operation of turbocharged diesel engines has been associated with slow acceleration rate, hence poor driveability, and overshoot in particulate, gaseous and noise emissions. Despite the relatively large number of published papers, this very important subject has been treated in the past scarcely and only segmentally as regards reference books. Merely two chapters, one in the book Turbocharging the Internal Combustion Engine by N. Watson and M. S. Janota (McMillan Press, 1982) and another one written by D. E. Winterbone in the book The Thermodynamics and Gas Dynamics of Internal Combustion Engines, Vol. II edited by J. H. Horlock and D. E. Winterbone (Clarendon Press, 1986) are dedicated to transient operation. Both books, now out of print, were published a long time ago. Then, it seems reasonable to try to expand on these pioneering works, taking into account the recent technological advances and particularly the global concern about environmental pollution, which has intensified the research on transient (diesel) engine operation, typically through the Transient Cycles certification of new vehicles.
