Low Pressure Fuel Injection TRIZ Cases
- Fuel Distributor Mounting Supports via Soldered Sheet-Metal Brackets
Sheet-metal mounting brackets bond to a forged stainless steel base body, reducing material removal and weight while maintaining mechanical strength.
- Fuel Rail End Seal Using Threaded Cap and Brazed Collar
Segmenting the seal into a brazed collar, threaded cap, and gasket distributes stress to prevent breakage at high injection pressures.
- Fuel Injector Pin Retainer Cup for Rotation Restriction
Segmented pin and cup mounting restricts inlet body rotation relative to the holder, resolving alignment precision versus complexity trade-offs.
- Tubular Debris Shield for Fuel Injector Control Valve
Transverse holes in a tubular shield filter debris from high-pressure fuel, preventing damage to the sensitive control valve seat.
- Tubular Rail Milling for High-Pressure Fluid Connection
Milled shoulders on a tubular rail enable secure coaxial gripping, eliminating bulky brackets and reducing system weight.
- Fuel Delivery Damper for Pressure Pulsation Control
Flexible members deflect into air chambers to dampen fuel pressure pulsations, ensuring accurate injector delivery.
- Fluid Conduit Damper With Sealed Vent For Brazing
A fluid conduit damper features a sealed vent to release trapped gases during assembly.
- Fuel Injector Valve Pressure Balancing and Spray Shaping
Metering passage creates pressure differential to stabilize fuel flow rate independent of inlet pressure variations.
- Fuel Injector Leakage Limitation via Atmospheric Air Intake Valve
An atmospheric air intake valve prevents sub-atmospheric pressure in the fuel conduit during cooling cycles, eliminating fuel leakage and vapor migration.
