Book Description
Experimental root cause analysis of low-speed pre-ignition mechanisms on a turbocharged gasoline engine with direct-injection
Author: Thorsten Schweizer
Publisher: Logos Verlag Berlin GmbH
ISBN: 3832582428
Category : Technology & Engineering
Languages : en
Pages : 140
Book Description
The concept of increasing power density is a successful approach to improving the conflict between efficiency and emission behavior of spark-ignition engine drive units for light-duty vehicles. This leads to highly charged gasoline engines with direct injection and high specific torque and power densities, promoting a not yet fully understood combustion anomaly known as low-speed pre-ignition (LSPI). This unpredictable, multicyclic phenomenon limits the depictable in-cylinder pressures, further efficiency gains and engine reliability. Only with a holistic understanding of the LSPI root cause mechanisms and processes can targeted countermeasures be taken and further efficiency gains achieved. A novel methodology pathway for LSPI root cause analysis was developed to accompany the entire LSPI event emergence process path by means of a multi-experimental approach on a modern high efficiency engine. This includes the identification of key LSPI activity – engine parameter specification relations, minimally invasive high-speed endoscopic imaging and further LSPI key experiments. Only the accumulation of inorganic substances originating from lubricating oil additives enables specific deposits/particles to ignite the surrounding mixture over a multicyclic process due to the resulting increased oxidation reactivity. Through a final synthesis step of all results, a multi-cycle oxidation-reactivity-enhanced deposit/particle-driven LSPI root cause mechanism is established.

Fuel Property Estimation and Combustion Process Characterization
Author: Yen-Hsiung Kiang
Publisher: Academic Press
ISBN: 0128134747
Category : Science
Languages : en
Pages : 461
Book Description
Fuel Property Estimation and Combustion Process Characterization is a thorough tool book, which provides readers with the most up-to-date, valuable methodologies to efficiently and cost-effectively attain useful properties of all types of fuels and achieve combustion process characterizations for more efficient design and better operation. Through extensive experience in fuels and combustion, Kiang has developed equations and methodologies that can readily obtain reasonable properties for all types of fuels (including wastes and biomass), which enable him to provide guidance for designers and operators in the combustion field, in order to ensure the design, operation, and diagnostics of all types of combustion systems are of the highest quality and run at optimum efficiency. Written for professionals and researchers in the renewable energy, combustion, chemical, and mechanical engineering fields, the information in this book will equip readers with detailed guidance on how to reliably obtain properties of fuels quickly for the design, operation and diagnostics of combustion systems to achieve highly efficient combustion processes. - Presents models for quick estimation of fuel properties without going through elaborate, costly and time consuming sampling and laboratory testing - Offers methodologies to determine combustion process characteristics for designing and deploying combustion systems - Examines the fundamentals of combustion applied to energy systems, including thermodynamics of traditional and alternative fuels combustion - Presents a fuel property database for over 1400 fuels - Includes descriptive application of big data technology, using dual properties analysis as an example - Provides specific technical solutions for combustion, fuels and waste processing
