Modelling of a Diesel Engine Common Rail Injection System
This paper is devoted to the modelling of a Diesel Common Rail Injection System. The objective is twofold : to build a simulator which will be used later for the rail pressure control scheme validation, and to get linearized models for control design. A mathematical model, based on physical equations is developed and used as a simulator. Then time responses of the rail pressure of a real engine...
متن کاملNonlinear modelling and control of a common rail injection system for diesel engines
Modern trends in designing mechatronic systems call for a synergic design of the separated subsystems (mechanic, electronic parts, control modules, etc.) concurring to the overall performance. Following this point of view, this paper presents a control oriented model and a nonlinear control design for a Common Rail injection system. First a model is developed, which is tuned in a virtual simula...
متن کاملNumerical investigation the effect of accumulator on reducing the pressure waves in a common rail fuel injection system of diesel engine
Pressure fluctuations during fuel injection are one of the factors that negative effect on performance of diesel engine. These fluctuations are caused by the rapid opening and closing of the nozzles and the creation of pressure waves in the fuel rail. One way to control these pressure fluctuations is to change the injector design and use an accumulator in the injector. This study is performed t...
متن کاملReduction of emissions and fuel consumption of diesel engine by using common rail fuel injection and aftertreatment systems
In this experimental study, the fuel system of the OM364 diesel engine manufactured by IDEM company, which operates in the basic mode with inline fuel pump and mechanical governor control, is upgraded to a common rail system with electronic control by the ECU. Also, emmssion of exhaust gases is reduced by SCR and DOC catalysts then performance and emmission parameters of engine are compared i...
متن کاملHybrid Modelling and Control of the Common Rail Injection System
We present an industrial case study in automotive control of significant complexity: the new common rail fuel injection system for Diesel engines, currently under production by Magneti Marelli Powertrain. In this system, a flow–rate valve, introduced before the High Pressure (HP) pump, regulates the fuel flow that supplies the common rail according to the engine operating point. The standard ap...
