Abstract (en)
[origin: EP1614894A1] The system has a hydraulic circuit comprising a distributor (16), and chambers (17, 19) in communication with the distributor through corresponding check valves (18, 20). The chambers communicate with each other through a balancing conduit (21). The chambers are connected near a fuel injection orifice and have a volume between 200 cubic millimeters to 600 cubic millimeters, where a wall of one of the chambers is elastic.
