Fuel Injection Apparatus TRIZ Cases
- Piezoelectric Actuator Transition Piece Positioning
An injection-molded plastic frame on a metallic transition piece prevents relative movement between the actuator and base, eliminating copper wire stress.
- Spark Plug Side Electrode Mechanical Attachment
A spark plug side electrode uses a flared wire portion to wedge an electrode tip into place without welding.
- Fuel Injector Safety Valve for Pressure Relief
A fuel injector safety valve reduces internal pressure differences by allowing controlled fluid escape.
- Fuel Delivery Drive Line Integrated into Filter Housing
Integrating the suction jet pump drive line into the filter housing eliminates separate supply lines, reducing manufacturing complexity and assembly costs.
- Multilayer Piezo Element Thick-Walled Metal Cover Layer
A multilayer piezoelectric element uses a metal cover layer with a thick-walled portion to secure the external electrode plate.
- Internal Combustion Engine Injector Nozzle Hole Diameter Configuration
A fuel injector nozzle uses a larger sixth hole to direct spray into the cylinder vortex center.
- Fuel Injection Valve Bracing Element for Stroke Stability
A preloaded bracing element isolates hydraulic deformation to preserve magnet armature stroke stability under high pressure.
- Piezoelectric Element Resin Buffer Suppresses Bonding Cracks
A resin layer buffers thermal stress on the conductive bonding material in laminated piezoelectric elements.
- Fuel Injector Valve Needle Closing Throttle Design
Integrating a closing throttle into the valve needle via segment-shaped recesses stabilizes closure behavior and reduces construction complexity.
