This book was released on 1997 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: This quarter started out with fresh ability to perform sustained engine operation on gas because of the successful operation of the gas compressor last quarter. The authors have completed baseline tests recording emissions and efficiency numbers. This gives the authors data that they have never before been able to acquire in the facility. In addition to the baseline data they have recorded data with a host of additional engine variables. These variables include the adjustments of ignition timing, air fuel ratio, air inlet temperatures and some propane seeding of the injected gas. With the background data on record they will be able to properly measure the level of positive impact that the port gas injection system provides. The remaining time in this quarter has been focused on completing the application of the port style gas injection system. The next steps in this project all pivot on the application of this port injection system. They have also progressed in the evaluation of the cylinder/engine monitoring system.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dual fuel engines utilize two different fuels consisting of a high reactivity fuel (HRF)injected into the cylinder and a low reactivity fuel (LRF), typically fumigated into the intakemanifold. In order to reduce the emissions of nitrogen oxides when compared against dieselcombustion, dual fuel engines begin the injection process early in the combustion cycle.However, at early injection timings dual fuel engines exhibit high emissions of both unburnedhydrocarbons (HC) and carbon monoxide (CO). This work discusses the emissions optimizationprocess to reduce emissions for two different fueling types, diesel-propane and poly-oxymethylene dimethyl ether (POMDME)-propane, on a single cylinder research engine (SCRE)based upon a PACCAR MX-11 heavy-duty engine while maintaining combustion and fuelconversion efficiencies.The parameters swept during this optimization process include start of injection, percentenergy substitution, a second injection and its timing, the split ratio - or the ratio of commandedduration of the first injection to that of the second, a coupled injection sweep, rail pressure, andintake pressure. These parameters were varied at a fixed gross indicated mean effective pressure(IMEPg) of 5 bar to represent low load operation as well as a fixed engine speed of 1339 rpm("B speed" of the SCRE). During all experiments a global limit of 1 g/kWh was set on theindicated specific NOx emissions, as well as a maximum pressure rise rate of 10 bar/deg, and acoefficient of variation of IMEPg at or below 5%. Using these limits and the emissions tradeoffsbetween HC, CO and NOx, this work was able to demonstrate diesel-propane emissionsimprovements of HC and CO of 86.4% and 66.8% respectively when compared to the baseline, while POMDME-propane emissions showed improvements in HC and CO of 90.9% and 86.2%respectively. Additionally, POMDME emissions demonstrated zero measurable filter smokenumber during all engine operations. A preliminary life cycle analysis of using both dual fuelcombinations have been compared against traditional diesel operation as well as battery poweredoperation and is found within the appendix of this work.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With increasingly restrictive NO x and particulate matter emissions standards, the recent discovery of new natural gas reserves, and the possibility of producing propane efficiently from biomass sources, dual fueling strategies have become more attractive. This paper presents experimental results from dual fuel operation of a four-cylinder turbocharged direct injection (DI) diesel engine with propane or methane (a natural gas surrogate) as the primary fuel and diesel as the ignition source. Experiments were performed with the stock engine control unit at a constant speed of 1800 rpm, and a wide range of brake mean effective pressures (BMEPs) (2.7-11.6 bars) and percent energy substitutions (PESs) of C 3 H 8 and CH 4. Brake thermal efficiencies (BTEs) and emissions (NO x, smoke, total hydrocarbons (THCs), CO, and CO 2) were measured. Maximum PES levels of about 80-95% with CH 4 and 40-92% with C 3 H 8 were achieved. Maximum PES was limited by poor combustion efficiencies and engine misfire at low loads for both C 3 H 8 and CH 4, and the onset of knock above 9 bar BMEP for C 3 H 8. While dual fuel BTEs were lower than straight diesel BTEs at low loads, they approached diesel BTE values at high loads. For dual fuel operation, NO x and smoke reductions (from diesel values) were as high as 66-68% and 97%, respectively, but CO and THC emissions were significantly higher with increasing PES at all engine loads.

Available in PDF, EPUB and Kindle. Book excerpt: This new volume covers the important issues related to environmental emissions from SI and CI engines as well as their formation and various pollution mitigation techniques. The book addresses aspects of improvements in engine modification, such as design modifications for enhanced performance, both with conventional fuels as well as with new and alternative fuels. It also explores some new combustion concepts that will help to pave the way for complying with new emission concepts. Alternative fuels are addressed in this volume to help mitigate harmful emissions, and alternative power sources for automobiles are also discussed briefly to cover the switch over from fueled engines to electrics, including battery-powered electric vehicles and fuel cells. The authors explain the different technologies available to date to overcome the limitations of conventional prime movers (fueled by both fossil fuels and alternative fuels). Topics examined include: • Engine modifications needed to limit harmful emissions • The use of engine after-treatment devices to contain emissions • The development of new combustion concepts • Adoption of alternative fuels in existing engines • Switching over to electrics—advantages and limitations • Specifications of highly marketed automobiles • Emission measurement methods
