INTERNAL COMBUSTION ENGINE STORAGE-VOLUME FUEL INJECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a fuel injection system capable of obtaining high reliability by minimizing volume of a storage volume and removing disadvantage of a known device. SOLUTION: This injection system 1 is provided with a pump 7 for supplying high pressure fuel into the storage volume 6 for supplying a plurality of injectors 5. The pump 7 is provided with at least one reciprocating pump element 18 performing a compression stroke in synchronization with each fuel injection. The injection system 1 is provided with at least one controller for controlling total amount of fuel supplied to the storage volume 6 by the pump 7. This controller is controlled by a chopper controller 16 for modulating the fuel volume introduced into a compression chamber 20 during the intake stroke Ps-Pi, although delivery start instant To of the pumping element 18 during the compression stroke Pi-Ps is unequivocally defined by the fuel volume introduced.
