20220145839 · 2022-05-12 ·

The present invention relates to a nozzle of a fuel injector that comprises a pivotably symmetrical nozzle body having a hollow space for introducing a nozzle needle, a nozzle tip that is provided at one longitudinal end of the nozzle body and has openings for discharging fuel, a housing contact surface that is provided at the other longitudinal end of the nozzle body and serves the pressing at a housing of a fuel injector, and an overhang surface that is provided in the longitudinal extent of the nozzle body between the nozzle tip and the housing contact service and that serves the placement of a nozzle clamping nut. The nozzle is characterized in that the minimal distance of the pivot axis of the nozzle body from the overhang surface is smaller than the minimal distance of the pivot axis of the nozzle body from the housing contact surface.

Slim-profile fuel injector for tight packaging in top feed fuel system

A fuel injector includes an injector housing defining a longitudinal axis extending between a first axial injector end and a second axial injector end. The injector housing includes an upper body piece forming the first axial injector end and including a fuel connector defining a connector axis intersecting the longitudinal axis. The injector housing further includes a nozzle having formed therein a plurality of spray outlets, and including a nozzle terminal tip. An injector full diameter (FD) is defined by the upper body piece. An axial distance (AD) is defined between an intersection of the connector axis and the longitudinal axis, and the nozzle terminal tip. A ratio of AD to FD is from 4.8 to 5.1.

FLUID INJECTOR MOUNTING CUP

A fuel injector cup includes a body having a first opening configured to receive fuel into the body and a second opening configured to receive a fuel injector for dispensing fuel. The cup further includes a mounting flange coupled with the body and extending therefrom, the mounting flange configured to be connected to a support surface to secure the cup to the support surface. The cup also includes a locating member coupled with at least one of the body or the mounting flange, the anti-rotation member configured to engage the fuel injector when received in the body and to orient and prevent rotation of the fuel injector relative to the body.

Valve cover load deflection limiting system
11434790 · 2022-09-06 · ·

A system comprises a component manufactured via additive manufacturing. The component includes a first material with a first contraction rate. An insert is disposed in the component and comprises a second material with a second contraction rate that is lower than the first contraction rate. When the component and the insert are exposed to a temperature suitable for sintering, the component contracts around the insert, thereby coupling the insert and the component.

DIGITAL INLET VALVE FOR A GASOLINE DIRECT INJECTION SYSTEM OF A MOTOR VEHICLE
20210262426 · 2021-08-26 ·

A digital inlet valve (DIV) for a gasoline direct injection (GDI) system of a motor vehicle is provided. The DIV includes a valve seat that seals a high pressure gasoline chamber of the GDI system against a low pressure gasoline chamber of the GDI system in a closed configuration of the DIV. A valve piston moves the valve seat between the closed configuration and an open configuration of the DIV, in which the high pressure gasoline chamber is in fluid connection with the low pressure gasoline chamber. A valve actuator actuates movement of the valve piston. The valve seat, the valve piston and the valve actuator are separate components, which are selectively plugged into each other.

Duct assembly for fuel injection systems in engines

A duct assembly for a fuel injector of an engine includes a base and multiple duct bodies. The base includes a number of spaced apart receptacles. Each receptacle defines a cavity with a receptacle axis, a rotational engagement surface, and an axial engagement surface. The duct bodies are correspondingly secured within the cavities. Each duct body defines an axis and a duct extending along the axis to provide a passage for a fuel jet from the fuel injector. Each duct body defines an axial alignment surface engaging the axial engagement surface of the receptacle in which it is disposed to axially align the duct body along the receptacle axis of the corresponding receptacle.
