A physics-based time-varying transport delay oxygen concentration model for dual-loop exhaust gas recirculation (EGR) engine air-paths

Experimental investigation of the influence of internal and external EGR on the combustion characteristics of a controlled auto-ignition two-stroke cycle engine

“…In-cylinder gas temperature must be http://dx.doi.org/10.1016/j.apenergy.2014.08.006 0306-2619/Ó 2014 Elsevier Ltd. All rights reserved. sufficiently high to initiate and sustain chemical reactions leading to auto-ignition processes [13][14][15][16][17][18]. In a typical two-stroke engine, the average charge temperatures at low and high loads are not high enough to maintain stable CAI combustion [19][20][21].…”

Effects of a Dual-Loop Exhaust Gas Recirculation System and Variable Nozzle Turbine Control on the Operating Parameters of an Automotive Diesel Engine

“…On the other hand, investigations on dual loop EGR systems were developed mainly through numerical simulations [22][23][24], limiting test bench activities to model validation. Consequently, little experimental information on the application of hybrid EGR systems in current downsized automotive diesel engines is available.…”

Control oriented modeling and analysis of gas exchange and combustion processes for LTC diesel engine

“…With the development of modern control theory, more and more new control algorithm have gradually been applied in diesel engine control. In recent years, study on gas exchange modeling for diesel LTC combustion control has made some progress [5,[13][14][15][16]. All these works will contribution to the LTC combustion control.…”
