Title:
【発明の名称】閉止ノズル燃料噴射装置
Document Type and Number:
Japanese Patent JP2790619
Kind Code:
B2
Abstract:
An injection rate shaping nozzle assembly (52) for a fuel injector is provided which includes a closed nozzle valve element (66) and a rate shaping control device (82) including an injection spill circuit for spilling a portion of the fuel to be injected to produce a predetermined time varying change in the flow rate of fuel injected into a combustion chamber. The spill circuit includes a spill passage (88) integrally formed in the nozzle valve element (66). The rate shaping control means (82) may include a spill valve (86) for controlling the spill flow through the spill circuit to create a low injection flow rate followed by a high injection flow rate. The spill passage (88) may communicate with the injector nozzle cavity (58) between injection events or alternatively may be blocked to prevent spill flow between injection events. The rate shaping control device (82) may include a spill accelerating device in the form of a spill chamber formed in the nozzle valve element (66) for creating a rapid increase in the spill flow rate.
