Method for correcting control function for injector of injection engine, involves determining internal pressure in cylinder of injection engine which is assigned to injector

摘要

#CMT# #/CMT# The method involves determining an internal pressure in a cylinder of an injection engine which is assigned to the injector. The internal pressure in the cylinder controls the fuel injection timing. The influence of the internal pressure on actual injected fuel quantity is determined. The control duration is corrected for compensating a deviation of the determined actual injected fuel quantity from the target injected fuel quantity. #CMT# : #/CMT# An independent claim is included for a device for correcting a control function for an injector of an injection engine. #CMT#USE : #/CMT# Method for correcting a control function for an injector of an injection engine. #CMT#ADVANTAGE : #/CMT# The influence of the internal pressure on actual injected fuel quantity is determined, and the control duration is corrected for compensating a deviation of the determined actual injected fuel quantity from the target injected fuel quantity, and hence ensures precise and improved control of the injector and thus ensures accurate metering of the injected fuel. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a graphical representation of flow rate of injected fuel for different conditions as function of the time during injection process.
