Title:
INJECTOR ASSEMBLY AND METHOD OF USING SAME
Document Type and Number:
WIPO Patent Application WO/2016/118012
Kind Code:
A3
Abstract:
An assembly at least comprising a fuel injector for dual fuel operation of an internal combustion engine. The assembly includes a nozzle holder defining a fuel circuit and provided with a nose adapted in use to be in connection with a combustion space of an internal combustion engine, and first and second nozzles in communication with the fuel circuit in the nozzle holder for directly injecting liquid fuel into the combustion space of the internal combustion engine for ignition of a combustible mixture present in the combustion space. The first and second nozzles adjacent to the nose of the nozzle holder are interconnected by a cooling channel. At each actuation of a fuel pump upstream of the first and second nozzles, substantially a full volume of fuel pumped during actuation of the fuel pump is allowed to flow through the cooling channel and via the first and second nozzles, to provide cooling thereof. The assembly further comprises a spill valve in the fuel circuit. Opening and closing of the spill valve controls the amount of liquid fuel to be delivered to the first and second nozzles.
