Abstract
Official abstract text for this publication.
A fuel injection valve injects a fuel into the combustion chamber or into the injection port of an internal combustion engine, the valve being actuated by an actuator assembly that includes a small displacement actuator and a large displacement actuator. The method includes commanding the small displacement actuator to move the valve member to a first open position corresponding to a first flow area and commanding the large displacement actuator to move the valve member to a second open position corresponding to a second flow area that is larger than the first flow area such that the ratio between the second flow area and the first flow area is at least 15:1. The fuel injection valve can also be operated to alternatively inject two different fuels, one of the fuels being a gaseous fuel and the other one being a liquid fuel.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of actuating a directly actuated fuel injection valve, said method comprising: (a) biasing a valve member in a closed position at which fuel flow through said valve is blocked by applying a closing force to said valve member; and (b) activating an actuator assembly comprising a large displacement actuator and a small displacement actuator which are each independently operable to produce a lift of said valve member away from a valve seat by: (i) c…
