两级增压流通特性对柴油机高密度-低温燃烧过程的影响机制的基础研究与进展
Basic Research and Development of the Influence Mechanism of Two-stage Turbocharged Flow Characteristics on High Density Low Temperature Combustion Process of Diesel Engine
摘要
Abstract
Based on the theory of high density - low temperature combustion,the effect of flow characteristics of Two-stage super-charged diesel on gas system related parameters,mixed process,combustion reaction and emission generation mechanism and the basis of scientific problems are evaluated. Reasonable organization of high density charge in cylinder is not uniformity in time and space distri-bution state.The atomization and distribution characteristics of diesel fuel are the key to improve the combustion characteristics and emis-sion characteristics of diesel engine. Furthermore, coordinating relations between the ultra-high supercharging technology and the fuel injection strategy, the variable valve technology and the EGR technology is the technical route of the heavy duty diesel engine to achieve efficient clean combustion in the whole working condition range.关键词
