Book Synopsis Experimental Investigations on Fuel Spray and Impingement for Gasoline Direct Injection Engines by : Hongliang Luo
Download or read book Experimental Investigations on Fuel Spray and Impingement for Gasoline Direct Injection Engines written by Hongliang Luo and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spray-wall impingement is a widespread phenomenon applied in many fields, including spray-wall cooling system, spray coating process and fuel spray and atomization in internal combustion engines. In direct-injection spark ignition (DISI), it is difficult to avoid the fuel film on the piston head and cylinder surfaces. The wet wall caused by impingement affects the air-fuel mixture formation process, which finally influence the subsequent combustion efficiency and performance. Therefore, the fuel spray and impingement under gasoline engine-like conditions were characterized. Mie scattering technique was applied to visualize the spray evolution and impingement processes in a high-pressure and high-temperature constant chamber. Meanwhile, the adhered fuel film on the wall was measured by refractive index matching (RIM) under non-evaporation and evaporation conditions considering the effects of different injection pressures, ambient pressures and ambient temperatures. Additionally, the fuel film formation and evaporation evolution models were proposed with the help of these mechanisms.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the International Symposium on Alternative and Advanced Automotive Engines, held in Vancouver, B.C., on August 11 and 12, 1986. The symposium was sponsored by EXPO 86 and The University of British Columbia, and was part of the specialized periods program of EXPO 86, the 1986 world's fair held in Vancouver. Some 80 attendees were drawn from 11 countries, representing the academic, auto motive and large engine communities. The purpose of the symposium was to provide a critical review of the major alternatives to the internal combustion engine. The scope of the symposium was limited to consideration of combustion engines, so that electric power, for example, was not considered. This was not a reflec tion on the possible contribution which electric propulsion may make in the future, but rather an attempt to focus the proceedings more sharply than if all possible propulsion systems had been considered. In this way all of the contributors were able to participate in the sometimes lively discussion sessions following the presentation of each paper.

Download or read book Experimental Investigation of Fuel-Reactivity Controlled Compression Ignition (RCCI) Combustion Mode in a Multi-Cylinder, Light-Duty Diesel Engine written by and published by . This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study was performed to provide the combustion and emission characteristics resulting from fuel-reactivity controlled compression ignition (RCCI) combustion mode utilizing dual-fuel approach in a light-duty, multi-cylinder diesel engine. In-cylinder fuel blending using port fuel injection of gasoline before intake valve opening (IVO) and early-cycle, direct injection of diesel fuel was used as the charge preparation and fuel blending strategy. In order to achieve the desired auto-ignition quality through the stratification of the fuel-air equivalence ratio (), blends of commercially available gasoline and diesel fuel were used. Engine experiments were performed at an engine speed of 2300rpm and an engine load of 4.3bar brake mean effective pressure (BMEP). It was found that significant reduction in both nitrogen oxide (NOx) and particulate matter (PM) was realized successfully through the RCCI combustion mode even without applying exhaust gas recirculation (EGR). However, high carbon monoxide (CO) and hydrocarbon (HC) emissions were observed. The low combustion gas temperature during the expansion and exhaust processes seemed to be the dominant source of high CO emissions in the RCCI combustion mode. The high HC emissions during the RCCI combustion mode could be due to the increased combustion quenching layer thickness as well as the -stratification at the periphery of the combustion chamber. The slightly higher brake thermal efficiency (BTE) of the RCCI combustion mode was observed than the other combustion modes, such as the conventional diesel combustion (CDC) mode, and single-fuel, premixed charge compression ignition (PCCI) combustion mode. The parametric study of the RCCI combustion mode revealed that the combustion phasing and/or the peak cylinder pressure rise rate of the RCCI combustion mode could be controlled by several physical parameters premixed ratio (rp), intake swirl intensity, and start of injection (SOI) timing of directly injected fuel unlike other low temperature combustion (LTC) strategies.
Book Synopsis Computational Investigation of Optimal Heavy Fuel Direct Injection Sark Ignition in Rotary Engine by : Asela A. Benthara Wadumesthrige

This book was released on 2011 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this computational study is to investigate the optimum injection and spark parameters for the direct injection spark ignition (DISI) Wankel rotary engine using diesel fuel. Currently only port fuel injected gasoline rotary engines are available in the automotive industry. Compared to reciprocating type engines rotary engine is mechanically simple, less vibrate, have higher power to weight ratio and achieve better performance at high rpm. Due to the inherent low fuel efficiency of rotary engine and increasing gas prices, application of the rotary engine in conventional automobiles is decreasing. This project seeks to introduce DISI technology to the rotary engine thus increase the fuel efficiency allowing it to be another efficient power source option for aero and automotive applications. DISI technology is the latest trend in the automobile manufacturing. This technology helped to combine benefits of both compression ignition (CI) and spark ignition (SI) engines into a single efficient internal combustion process. Multi-fuel capabilities, reduced operating pressures, and reduced compression ratios make this technology applicable for rotary engines. In this study diesel fuel, as opposed to gasoline, is introduced into the rotary engine using DISI technology. Due to high technological advancements used in DISI engines, it is expensive to experimentally incorporate this technology to a new engine. Accurately designed computational analyses can reduce both time and cost by cutting extra experimental test trials. For this computational fluid dynamics (CFD) study ANSYS FLUENT commercial software was used to integrate the DISI technology into a rotary engine model which was designed in Solidworks and meshed in GAMBIT. When creating the engine model, many parameters have to be considered. Engine geometry, injectors, and spark plugs were identified as the most important components needed to be investigated when integrating DISI technology into the rotary engine. By using a readily available rotary engine, direct injector, and spark plug, the number of parameters for the optimization process were reduced. The most important parameters were picked to evaluate the optimum single injection and spark locations. Full factorial experimental design was used to estimate the sensitivity of different combinations of parameters. This was followed by a statistical sensitivity study using JMP 800 commercial software to determine the most and least sensitive parameters to analyze for the optimum setup of single injection rotary engine combustion. Contour plots of fuel consumption, CO2 generated, equivalence ratio, average temperatures, and pressures were used to support the results. The feasibility of multiple injections was also studied by means of their power outputs and fuel efficiencies. Optimum locations, amounts of fuel, number of orifices and orientations of orifices were included when evaluating optimum lead (second) injector. Similar studies were carried out to check the applicability of a third injector. From the results it can be observed that a dual injection setup provided optimum performance from the DISI rotary engine.
