Fuel injection system for internal combustion engine of diesel vehicle, has electronic control unit determining set point and correction of set point of controlled flow regulator, where unit is connected to regulator

摘要

#CMT# #/CMT# The system has a high pressure fuel pump (8) and a fuel injector (14) at an exhaust. A controlled flow regulator (13) and an electronic control unit (16) permit to limit the flow variations in the upstream of the pump during fuel injection phases in the upstream of the filter. The unit (16) is connected to the regulator and is capable of determining a set point and a correction of the set point of the regulator. The unit (16) has a determining unit (18) to determine the anticipative correction of a flow set point of the regulator. #CMT# : #/CMT# An independent claim is also included for a method for injecting fuel of an internal combustion engine provided with a particle filter. #CMT#USE : #/CMT# System for injecting fuel from an internal combustion engine of a diesel vehicle, for use in field of particle filter regeneration and for controlling injection in an internal combustion engine. #CMT#ADVANTAGE : #/CMT# The system permits to regulate flow of fuel in different units of the engine in order to maintain performance of the engine during regeneration of the particle filter. The system permits to correct the variations of pressure in common ramp for supply during regeneration phases of the particle filter. The system permits to limit fluctuations of the pressure in the common supply ramp, while permitting to limit the impact of the regeneration phases on the performances and pleasure of driving perceived by the driver. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows major components of fuel injection system. 8 : High pressure fuel pump 13 : Controlled flow regulator 14 : Fuel injector 16 : Electronic control unit 18 : Anticipative correction determining unit.
