Common-rail control device for fuel injection system in e.g. watercraft, has control units that supplies different motor control signals as respective filtered, and unfiltered variable signals to actuator connection in switch unit

摘要

#CMT# #/CMT# The control device (500) has first, second and third control units (510,520,530) that are configured and adapted for generating a motor control signal. The motor control signal is supplied from one controller of three control units as filtered, manipulated variable signal to actuator connection (571,572) in switch unit (570), while the motor control signal is supplied as unfiltered, variable signal from remaining controllers among three control units to actuator connection. #CMT# : #/CMT# An independent claim is included for injection system. #CMT#USE : #/CMT# Common-rail control device for fuel injection system connected to internal combustion engine such as diesel engine in watercraft, and emergency power generator in power plant (all claimed) such as nuclear power plant. #CMT#ADVANTAGE : #/CMT# The high reliability and operation safety of the common-rail control device are improved efficiently, by the provision of system controller, actuator and set of sensors. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of the common-rail control device in two redundancy structures. 500 : Common-rail control device 510,520,530 : Control units 570 : Switch unit 571,572 : Actuator connections 582 : Control signal.
