Available in PDF, EPUB and Kindle. Book excerpt: Abstract : The conventional internal combustion engine will continue to exist for a long time. Likewise, demand for higher output efficiencies, higher specific power output, increased reliability, and lower emissions will continue to grow. There is also a growing requirement to run on various gaseous fuels and natural gas, whether for environmental, economic, or resource conservation reasons. This dissertation investigates a 6.7L diesel engine converted to run stoichiometric diesel micro-pilot / natural gas premix combustion with a maximum diesel contribution target of 5% of the total fuel energy with a three-way catalyst aftertreatment. The research centers on investigating the dominant factors and their impact on the critical barriers of this technology, including the positive and negative impact on combustion stability at low loads, the most influential factors and their impact on maximizing thermal efficiency at medium loads, the controlling parameters at preventing combustion knock at high-loads, and the ability of the three-way catalyst to minimize emissions. A diesel-like efficiency of 41% brake thermal efficiency was achieved with a high load output of 23 bar brake mean effective pressure when operating in the micro-pilot mode. This operating condition reduced up to 25% brake-specific CO2 emissions compared to diesel-only. Low loads can be achieved by delaying combustion phasing, reducing the injection pressure, adding exhaust gas to the intake, and increasing the total diesel pilot quantity. Maintaining stable ignition of the diesel pilot becomes a challenge at low loads, as the intake pressure is reduced; the chamber pressure at diesel injection decreases, and the presence of a near-stoichiometric mixture of NG will act to inhibit the diesel ignition. As such, maintaining the stoichiometric combustion resulted in a minimum load output of 5 bar BMEP. The pilot injection pressure reduction improved combustion stability at lower loads. While lean operation enabled further load reduction, it precludes using a three-way catalyst to control NOx emissions. At medium loads, a design of experiments investigation revealed that, when the equivalence ratio is constrained at stoichiometric, exhaust gas recirculation and pilot injection timing are the most influential factors in controlling combustion and performance metrics. In contrast, intake air temperature and pilot injection pressure showed the least sensitivity. While it was possible to achieve 25 bar BMEP for high loads, such operation was limited by pre-ignition. Exhaust gas recirculation and pilot injection timing can mitigate abnormal combustion effectively. At a steady-state, near stoichiometric condition, it was observed that the catalyst operates efficiently, consistent with a three-way catalyst operation with very low NOx and unburned methane emissions. Overall, this dissertation demonstrates that diesel-like performance can be achieved with the stoichiometric micro-pilot concept and provides an understanding of the primary controlling factors and their limitations.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Dual fuel engine operation with premixed natural gas as the main fuel and diesel pilot ignition has been gaining interest among research and industry as natural gas is among the most promising existing alternative fuels. The dual fuel engine performance has been shown to equal and sometimes, depending on operating conditions, better the performance and efficiency of the diesel engine. Along with its advantages on the combustion high efficiency, diesel-like performance, and emissions of NOx and particulate matter reduction, some disadvantages are brought by the application of such operation. At light load conditions, there is an increase in CO and HC emissions, low fuel efficiency and combustion stability. While operating at higher loads, the dual fuel engine performance showed to be limited by combustion knock. This effectively reduces the maximum break mean effective pressure (BMEP) the engine can output when compared to a diesel engine. Although combustion knock is well defined in SI and diesel engines, dual fuel knock characterization still needs more investigation. This project centers on developing a fuel system for a diesel engine conversion to dual fuel to deliver high load and high efficiency. The selected engine has been converted to the dual fuel operation and dual fuel combustion has been demonstrated. After achieving the project goal of a high load and high efficiency dual fuel engine, the combustion knock in dual fuel operation will be characterized and a method for detection and intensity calculation will be modeled. The characterization will also be compared to spark ignition (SI) and reactivity-controlled compression ignition (RCCI) operating engines.

Download or read book Implementation and Control of Stoichiometric Natural Gas Combustion to Enable Low emission Diesel Engines written by Nathaniel Bryce Oliver and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The expected growth in the heavy-duty transportation sector necessitates the development of engine technologies able to increase efficiency and reduce emissions without sacrificing power output. Previous research has demonstrated that reducing heat transfer losses from the cylinder can enable significant efficiency gains in Diesel engines. The high in-cylinder temperatures generated in this engine architecture enable the use of low-cetane fuels with the potential for low-soot operation. Low soot emissions allow the equivalence ratio to be increased to stoichiometric which increases power, and could allow the existing Diesel aftertreatment system to be replaced with a less-expensive three-way catalyst. Natural gas is a promising candidate for stoichiometric, high-temperature, Diesel-style combustion. Its high hydrogen-to-carbon ratio should be able to reduce both soot and carbon dioxide emissions, and its wide distribution as a commercial and residential fuel provides existing infrastructure to speed deployment in transportation applications. This thesis demonstrates stoichiometric, Diesel-style combustion of neat methane as a single-component surrogate for natural gas. It explores the challenges of injecting a gaseous fuel at high pressures, and demonstrates the fuel's capacity for low emissions. It then provides a preliminary investigation into multiple-injection strategies for controlling combustion behavior and emissions in a stoichiometric, high-temperature engine architecture. First, fuel system hardware is developed to enable gaseous operation and preliminary experimentation is accomplished with methane. A fuel compression system is designed to supply methane at pressures suitably high to achieve good mixing and short injection durations, and a solenoid-actuated Diesel fuel injector is modeled and modified to inject methane at these pressures. This fuel injection system is then implemented on a single-cylinder engine. An insulated piston face, air cooled head, and intake preheating achieve suitable start of injection temperatures to ignite methane. Intake preheating is varied at low equivalence ratios to determine the sensitivity of engine performance to temperature at the lowest-load, lowest-temperature conditions of interest. A sweep of equivalence ratio demonstrates soot emissions roughly four times the current EPA limit for heavy-duty vehicles and combustion efficiencies of approximately 92% at stoichiometric fuel loading. High soot levels and low combustion efficiencies are also seen at the lowest equivalence ratios investigated. This suggests poorly mixed combustion, and poor injector performance. Second, injector dynamics are examined in greater detailed, and emissions performance is characterized with improved injector performance. High-speed Schlieren imaging is able to determine the injection dynamics contributing to high low-load emissions. A parametric modeling investigation suggests that reducing the injector plunger length is able to remove flow rate oscillations seen at long injection durations, and that the addition of dry friction is able to reduce the magnitude of low-momentum post injections occurring after injector closing. Dry friction is implemented using PTFE O-rings installed between the injector body and plunger. Imaging is used to confirm that a shortened plunger is able to remove long-duration oscillations, and to determine the number of O-rings necessary to suitably reduce post injection magnitude. The improved injector is used to repeat the sweep of equivalence ratios and demonstrates improved soot emissions at all operating conditions. Most notably, low-load soot emissions are reduced by more than a factor of ten, demonstrating the effectiveness of improved injector performance for improving emissions. Techniques for further improving injector performance and potential changes to injector design are discussed. Finally, the prospects for controlling combustion in a stoichiometric, low heat rejection Diesel engine using multiple injections are discussed and experimentally investigated. The applications and effects of multiple injection strategies in traditional Diesel engines are explored, and their potential extension to stoichiometric engines is discussed. Methanol engine operation enables the use of a fast-actuating piezoinjector and the realization of short injection pulses. A range of two-injection strategies are implemented in order to determine the sensitivity of engine operation to pilot, split-main, and post-injection timing and duration. Small pilot injections are found to have control authority over rate of pressure rise and peak pressure and show some promise for improving combustion efficiency. Post injections demonstrate authority over peak pressure and combustion efficiency. All of these effects are accomplished with minimal impact on engine work output. The experiments of this thesis demonstrate that, even with course control of injection, high-temperature, stoichiometric combustion of methane is able to greatly reduce soot emissions over traditional Diesel engines. Improved injector dynamics and the implementation of multiple injection strategies further improve emissions and combustion performance, suggesting substantial room for refinement of the technology and motivating the continued development of injector hardware and injection strategies. The ability to operate a Diesel engine at stoichiometric fueled only by natural gas and to employ a three-way catalyst for emissions abatement makes this strategy a clean, efficient, high-torque, and low-cost solution for heavy-duty transportation.

This book was released on 2022 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Natural gas has been gaining popularity as an alternative fuel due to its high availability, low CO2 emissions, and low cost. In this experimental study, water injection's impact on medium and heavy-duty engine operation fueled by natural gas and pilot diesel injection for ignition was studied under stochiometric operation for use with a three-way catalytic converter to meet criteria emissions for off-road power generation. To retain high efficiencies, a high compression ratio of 17.3:1 was used. Maintaining stoichiometric operation with a high compression ratio leads to combustion knock, pre-ignition, and high NOx formation. Conventionally, cooled EGR can be used to reduce NOx, but results in increased soot and does not eliminate combustion knock and pre-ignition. As an alternative to EGR this work utilized port injected water to provide on demand charge cooling, successfully reducing both NOx and soot while enabling high-load operation. A combination of both high and low speeds and loads were tested to study the impact of water injection on the emissions and performance of the natural gas, diesel-pilot engine. Additionally, water injections impact on diesel only operation was tested to provide comparison metrics and aid in a better understanding of the mechanisms at work when injecting water in an internal combustion engine. At full load, 16.8 bar BMEP, it was found that a water to fuel ratio of 0.5:1 was sufficient to enabling the knock free operation without significant increase in combustion duration or instability where operating at this load without water resulted in pre-ignition. Increasing the water to fuel ratio to 1:1 enabled a 21 bar BMEP load. At 12.5 bar BMEP, the NOx emission was reduced from 13.5 g/kwh to 7.2 g/kwh with a water to fuel mass ratio of 1.5:1. In addition to solving the high NOx and pre-ignition problem, a water to fuel ratio of 2.5:1 at 16.8 bar BMEP also decreased the soot content in the exhaust by a factor of 3.5 with only a small penalty in efficiency, decreasing break thermal efficiency from 41 to 40%.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Universal concerns about degradation in air quality, stringent emissions regulations, energy scarcity, and global warming have prompted research and development of compressed ignition engines using alternative combustion concepts. Natural gas/diesel dual-fuel combustion is an advanced combustion concept for compression ignition diesel engines, which has attracted global attention in recent years. This combustion concept is accomplished by creating reactivity stratification in the cylinder via the use of two fuels characterized by distinctly different reactivities. The low reactivity and main fuel (i.e., natural gas) is firstly premixed with air and then charged into the cylinder through the intake manifold, and the high reactivity fuel (i.e., diesel) is then injected into the charged mixture through a direct injector. This combustion concept offers prominent benefits in terms of a significant reduction of particulate matter (PM) and sometimes nitrogen oxides (NOx) emissions while maintaining comparable fuel efficiency compared to diesel engine. However, low thermal efficiency and high greenhouse gas (GHG) emissions under low load conditions are major challenges which prevented the implementation of dual-fuel concept in commercial automative engines. The present study investigates different combustion approaches with the aim to enhance combustion performance and reduce emissions of unburned methane, CO, NOx, soot, and GHG of natural gas/diesel dual-fuel engines under different engine load-speed conditions. In particular, the main focus of this thesis is on low load conditions where GHG emissions of conventional natural gas/diesel dual-fuel engine is much higher than that of conventional diesel engine. Alongside the experimental study, a computational fluid dynamic (CFD) model is developed to help understand the behaviour of natural gas/diesel dual-fuel combustion process under different engine load-speed conditions. The studied approaches showed that the fuel efficiency and GHG emissions of natural gas/diesel dual-fuel engine can be significantly improved under low engine load conditions compared to diesel engine.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract : Among the various alternative fuels, natural gas is considered as a leading candidate for heavy-duty applications due to its availability and applicability in conventional internal combustion diesel engines. Compared to their diesel counterparts natural gas fueled spark-ignited engines have a lower power density, reduced low-end torque capability, limited altitude performance, and ammonia emissions downstream of the three-way catalyst. The dual fuel diesel/natural gas engine does not suffer with the performance limitations of the spark-ignited concept due to the flexibility of switching between different fueling modes. Considerable research has already been conducted to understand the combustion behavior of dual fuel diesel/natural gas engines. As reported by most researchers, the major difficulty with dual fuel operation is the challenge of providing high levels of natural gas substitution, especially at low and medium loads. In this study extensive experimental and simulation studies were conducted to understand the combustion behavior of a heavy-duty diesel engine when operated with compressed natural gas (CNG) in a dual fuel regime. In one of the experimental studies, conducted on a 13 liter heavy-duty six cylinder diesel engine with a compression ratio of 16.7:1, it was found that at part loads high levels of CNG substitution could be achieved along with very low NOx and PM emissions by applying reactivity controlled compression ignition (RCCI) combustion. When compared to the diesel-only baseline, a 75% reduction in both NOx and PM emissions was observed at a 5 bar BMEP load point along with comparable fuel consumption values. Further experimental studies conducted on the 13 liter heavy-duty six cylinder diesel engine have shown that RCCI combustion targeting low NOx emissions becomes progressively difficult to control as the load is increased at a given speed or the speed is reduced at a given load. To overcome these challenges a number of simulation studies were conducted to quantify the in-cylinder conditions that are needed at high loads and low to medium engine speeds to effectively control low NOx RCCI combustion. A number of design parameters were analyzed in this study including exhaust gas recirculation (EGR) rate, CNG substitution, injection strategy, fuel injection pressure, fuel spray angle and compression ratio. The study revealed that lowering the compression ratio was very effective in controlling low NOx RCCI combustion. By lowering the base compression ratio by 4 points, to 12.7:1, a low NOx RCCI combustion was achieved at both 12 bar and 20 bar BMEP load points. The NOx emissions were reduced by 75% at 12 bar BMEP while fuel consumption was improved by 5.5%. For the 20 BMEP case, a 2% improvement in fuel consumption was achieved with an 87.5% reduction in NOx emissions. At both load points low PM emissions were observed with RCCI combustion. A low NOx RCCI combustion system has multiple advantages over other combustion approaches, these include; significantly lower NOx and PM emission which allows a reduction in aftertreatment cost and packaging requirements along with application of higher CNG substitution rates resulting in reduced CO2 emissions.

This book was released on 2020 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: It's crucial to use advanced combustion strategies to increase efficiency and decrease engine-out pollutants because of the compelling need to reduce the global carbon footprint. This dissertation proposes dual fuel low-temperature combustion as a viable strategy to decrease engine-out emissions and increase the thermal efficiency of future heavy-duty internal combustion (IC) engines. In dual fuel combustion, a low reactivity fuel (e.g. methane, propane) is ignited by a high reactivity fuel (diesel) in a compression-ignited engine. Generally, the energy fraction of low reactivity fuel is maintained at much higher levels than the energy fraction of the high reactivity fuel. For a properly calibrated engine, combustion occurs at lean and low-temperature conditions (LTC). This decreases the chances of the formation of soot and oxides of nitrogen within the engine. However, at low load conditions, this type of combustion results in high hydrocarbon and carbon monoxide emissions. The first part of this research experimentally examines the effect of methane (a natural gas surrogate) substitution on early injection dual fuel combustion at representative low loads of 3.3 and 5.0 bar BMEPs in a single-cylinder compression ignition engine (SCRE). Gaseous methane fumigated into the intake manifold at various methane energy fractions was ignited using a high-pressure diesel pilot injection at 310 CAD. Cyclic combustion variations at both loads were also analyzed to obtain further insights into the combustion process and identify opportunities to further improve fuel conversion efficiencies at low load operation. In the second part, the cyclic variations in dual fuel combustion of three different low reactivity fuels (methane, propane, and gasoline) ignited using a high-pressure diesel pilot injection was examined and the challenges and opportunities in utilizing methane, propane, and gasoline in diesel ignited dual fuel combustion, as well as strategies for mitigating cyclic variations, were explored. Finally, in the third part a CFD model was created for diesel methane dual fuel LTC. The validated model was used to investigate the effect of methane on diesel autoignition and various spray targeting strategies were explored to mitigate high hydrocarbon and carbon monoxide emissions at low load conditions.
