Hybrid modelling and control of the common rail Injection System
International Journal of Control, 2007Co-Authors: Andrea Balluchi, Antonio Bicchi, E. Mazzi, A. Sangiovanni Vincentelli, Gabriele SerraAbstract:We present an industrial case study in automotive control of significant complexity: the new common-rail fuel-Injection System for Diesel engines under development at Magneti Marelli Powertrain. In this System, an inlet metering valve, inserted before the high pressure (HP) pump, regulates the fuel flow that supplies the common rail according to the engine operating point (e.g., engine speed and desired torque). The standard approach in automotive control based on a mean-value model for the plant does not provide a satisfactory solution as the discrete-continuous interactions in the fuel Injection System, due to the slow time-varying frequency of the HP pump cycles and the fast sampling frequency of sensing and actuation, play a fundamental role. We present a design approach based on a hybrid model of the Magneti Marelli Powertrain common-rail fuel-Injection System for four-cylinder multi-jet engines and a hybrid approach to the design of a rail pressure controller. The hybrid controller performs signific...

HSCC - Hybrid modelling and control of the common rail Injection System
Hybrid Systems: Computation and Control, 2006Co-Authors: Andrea Balluchi, Antonio Bicchi, E. Mazzi, A. Sangiovanni Vincentelli, Gabriele SerraAbstract: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 approach followed in automotive control is to use a mean–value model for the plant and to develop a controller based on this model. In this particular case, this approach does not provide a satisfactory solution as the discrete–continuous interactions in the fuel Injection System, due to the slow time–varying frequency of the HP pump cycles and the fast sampling frequency of sensing and actuation, play a fundamental role. We present a design approach based on a hybrid model of the Magneti Marelli Powertrain common–rail fuel–Injection System for four-cylinder multi–jet engines and a hybrid approach to the design of a rail pressure controller. The hybrid controller is compared with a classical mean–value based approach to automotive control design whereby the quality of the hybrid solution is demonstrated.

High pressure common rail Injection System modeling and control
ISA Transactions, 2016Co-Authors: H. P. Wang, D. Zheng, Yuan TianAbstract:In this paper modeling and common-rail pressure control of high pressure common rail Injection System (HPCRIS) is presented. The proposed mathematical model of high pressure common rail Injection System which contains three sub-Systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear System. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. For the considered HPCRIS, an effective model free controller which is called Extended State Observer ??? based intelligent Proportional Integral (ESO-based iPI) controller is designed. And this proposed method is composed mainly of the referred ESO observer, and a time delay estimation based iPI controller. Finally, to demonstrate the performances of the proposed controller, the proposed ESO-based iPI controller is compared with a conventional PID controller and ADRC.

Impact of Alternative Paraffinic Fuels on the Durability of a Modern Common Rail Injection System
Energies, 2020Co-Authors: Carmen Mata, Jakub Piaszyk, José A. Soriano, Jose Martin Herreros, Athanasios Tsolakis, Karl D. DearnAbstract:Common rail (CR) diesel fuel Injection Systems are very sensitive to variations in fuel properties, thus the impact of alternative fuels on the durability of the Injection System should be investigated when considering the use of alternative fuels. This work studies a high-pressure CR (HPCR) diesel fuel Injection System operating for 400 h in an Injection test bench, using a fuel blend composed of an alternative paraffinic fuel and conventional diesel (50PF50D). The alternative fuel does not have aromatic components and has lower density than conventional diesel fuel. The Injection System durability study was carried out under typical Injection pressure and fuel temperature for the fuel pump, the common rail and the injector. The results show that the HPCR fuel Injection System and its components (e.g., piston, spring, cylinder, driveshaft and cam) have no indication of damage, wear or change in surface roughness. The absence of internal wear to the components of the Injection System is supported by the approximately constant total flow rate that reaches the injector during the whole the 400 h of the experiment. However, the size of the injector nozzle holes was decreased (approximately 12%), being consistent with the increase in the return fuel flow of the injector and rail (approximately 13%) after the completion of the study. Overall, the Injection System maintained its operability during the whole duration of the durability study, which encourages the use of paraffinic fuels as an alternative to conventional diesel fuel.
