INSERTION DEVICE FOR FUEL INJECTION

An insert device for fuel injection has a body having an upper body portion coupled with a cylinder head of an engine cylinder, a lower body portion extending from the upper body portion toward a combustion chamber of the engine cylinder, an inner surface extending around a central volume positioned to receive liquid fuel from a fuel injector. The body includes a plurality of gas inlet channels and a plurality of fuel gas mixture outlet channels. The gas inlet channel directs gas into the central volume. The fuel-gas mixture outlet passage directs a fuel-gas mixture into the combustion chamber. The inner surface includes a plurality of recessed surface portions along a central axis of the body between the inlet channel and the outlet channel, the recessed surface portions being shaped to direct the gas entering the central volume toward the liquid fuel in the central volume. 一种用于燃料喷射的插入装置，其主体具有与发动机汽缸的汽缸盖联接的上主体部分、从所述上主体部分朝向所述发动机汽缸的燃烧室延伸的下主体部分、围绕中心容积延伸的内表面，所述中心容积被定位成从燃料喷射器接收液体燃料。所述主体包括多个气体入口通道和多个燃料气体混合物出口通道。所述气
