Advanced Modeling of Common Rail Injector Dynamics and Comparison with Experiments

Assessment of the impact of dynamic states of an internal combustion engine on its operational properties

“…The relative range of pollutant emission intensity in the vehicle 4) acceleration phase reached the highest value for the hydrocarbons emission while the lowest values of this relative range were recorded for the carbon dioxide emission intensity and for the fuel flow intensity. In general, a statement may be made that in the states of IC engine operation when the vehicle acceleration sign is positive, the average intensity of flow of the fuel consumed and the average pollutant emission intensity are higher than those corresponding to negative vehicle acceleration.…”

“…Most of the works concern the controlling of IC engines with taking into account dynamic states [4,12,14,17,23]. In publication [4], a mathematical model used to simulate the injector operation in a common rail engine fuelling system has been presented.…”

“…In publication [4], a mathematical model used to simulate the injector operation in a common rail engine fuelling system has been presented. Monograph [12], prepared at ETH in Zürich, shows the present-day state of knowledge regarding the modelling of working processes in IC engines in respect of the use of such processes in engine control systems.…”

Diesel locomotive efficiency and reliability improvement as a result of power unit load control system modernisation

“…Numerous studies on the subject have appeared. In the field of motor-car IC engines the majority of investigations are related to IC engine systems control including dynamic states [10,14,15,25,36,61]. In [11] an interesting mathematical model of transient processes in locomotive diesel engines was proposed.…”

Experimental investigation into the effects of two-stage injection on fuel injection quantity, combustion and emissions in a high-speed optical common rail diesel engine

“…Although, hydraulic effects of two-stage fuel injection has been previously reported [10,[19][20][21][22][23][24][25], the effects of advanced fuel injection modes on the fuel injection system are yet to be fully explored and few detailed in-cylinder studies have been carried out on the interaction of two-stage fuel injection and its effect on fuel injection quantity, combustion characteristics and exhaust emissions. The objective of this study was to investigate the effects of fuel injection equipment (FIE) characterisation and optimisation on diesel combustion and emissions with two-stage fuel injection.…”
