This book was released on 2016 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fuel injection process has been studied since the internal combustion engine was developed. Direct injection has been an integral part to the success of diesel engines, where there is minimal time for the fuel to mix with the compressed air. The benefits of fuel injection center on: fuel efficiency and lower toxic emissions. As the world depletes more fossil fuels each year it is imperative to concentrate research on techniques to lower fuel consumption. Past research on fuel sprays using laser techniques were limited by cross sensitivity in regards to the regions with both liquid and vapor phases present. Quantitative schlieren techniques have been proposed and investigated since the first half of the 20th century, but only recently with the rapid development of digital imaging techniques and computers have they have been used for quantitative analysis. This thesis presents the results for a new hardware installation for a rainbow schlieren diagnostic method. Experiments were performed using a constant pressure flow vessel (CPFV) and a modern common rail diesel injector to obtain high-speed images of the vaporizing fuel sprays. The CPFV ran under steady ambient thermodynamic conditions where the pressure and temperatures were controlled variables. Two cameras were used, Mie scatter liquid phase data and the rainbow schlieren vapor phase data were captured simultaneously. Quantitative results indicate that the axial and radial variation in the fuel sprays seem to match the well-validated variable profile model.

Available in PDF, EPUB and Kindle. Book excerpt: A work on turbulent premixed combustion is important because of increased concern about the environmental impact of combustion and the search for new combustion concepts and technologies. An improved understanding of lean fuel turbulent premixed flames must play a central role in the fundamental science of these new concepts. Lean premixed flames have the potential to offer ultra-low emission levels, but they are notoriously susceptible to combustion oscillations. Thus, sophisticated control measures are inevitably required. The editors' intent is to set out the modeling aspects in the field of turbulent premixed combustion. Good progress has been made on this topic, and this cohesive volume contains contributions from international experts on various subtopics of the lean premixed flame problem.

This book was released on 2009-12-18 with total page 761 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volume 2 of the two-volume set Advanced direct injection combustion engine technologies and development investigates diesel DI combustion engines, which despite their commercial success are facing ever more stringent emission legislation worldwide. Direct injection diesel engines are generally more efficient and cleaner than indirect injection engines and as fuel prices continue to rise DI engines are expected to gain in popularity for automotive applications. Two exclusive sections examine light-duty and heavy-duty diesel engines. Fuel injection systems and after treatment systems for DI diesel engines are discussed. The final section addresses exhaust emission control strategies, including combustion diagnostics and modelling, drawing on reputable diesel combustion system research and development. Investigates how HSDI and DI engines can meet ever more stringent emission legislation Examines technologies for both light-duty and heavy-duty diesel engines Discusses exhaust emission control strategies, combustion diagnostics and modelling

Download or read book Quantitative Imaging of Turbulent Mixing Dynamics in High Pressure Fuel Injection to Enable Predictive Simulations of Engine Combustion written by and published by . This book was released on 2015 with total page 49 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this LDRD project, we developed a capability for quantitative high - speed imaging measurements of high - pressure fuel injection dynamics to advance understanding of turbulent mixing in transcritical flows, ignition, and flame stabilization mechanisms, and to provide e ssential validation data for developing predictive tools for engine combustion simulations. Advanced, fuel - efficient engine technologies rely on fuel injection into a high - pressure, high - temperature environment for mixture preparation and com bustion. Howe ver, the dynamics of fuel injection are not well understood and pose significant experimental and modeling challenges. To address the need for quantitative high - speed measurements, we developed a Nd:YAG laser that provides a 5ms burst of pulses at 100 kHz o n a robust mobile platform . Using this laser, we demonstrated s patially and temporally resolved Rayleigh scattering imaging and particle image velocimetry measurements of turbulent mixing in high - pressure gas - phase flows and vaporizing sprays . Quantitativ e interpretation of high - pressure measurements was advanced by reducing and correcting interferences and imaging artifacts.
