摘要：When hot exhaust gas is mixed with inlet air,the charge to a diesel engine is modified in different ways:the charge temperature increases,the total charge mass is reduced and the charge composition changes.This paper is concerned with the residual gas fraction that is usually determined by straight CO2 measurement in a sample of gas extracted from a cylinder during the compression stroke.A general zero–dimensional model for calculating the residual gas fraction in reciprocating internal combustion engines has been formulated.The model accounts for both the trapped gas in the cylinder at top dead center and the back–flow of exhaust gas into the cylinder during the valve overlap period.The effect of EGR introduction has been discussed.
其他摘要：The article presents the analysis of the foil transfer technology for textiles:the equipment,materials,specific process.Technological factors that affect image quality and highlighted problems,which occur when transferring the foil to fabric,and methods for their solution are analyzed.
