Exhaust Gas Recirculation TRIZ Cases
- Eccentric Regulating Element for Engine Intake Flow Control
An eccentric regulating element with guide ribs directs air flow through an engine intake housing to optimize alignment and reduce turbulence.
- Multi-functional Module EGR Valve Upstream Heat Exchanger
Upstream EGR valve placement prevents carbon deposits while external vacuum source frees volume for larger heat exchanger.
- Curved Intake Manifold EGR Passage Integration
Curved intake pipes feature internal EGR gas passages formed at joint surfaces of divided pieces to optimize space usage.
- Air Intake Apparatus Thermal Insulation for EGR Condensation
An air intake apparatus uses a separate internal external gas passage to thermally isolate recirculated exhaust from the main body.
- Carburetor Intermediate Part Integrating Fuel Connections
Integrating fuel inlet, outlet, and compensation ports via an intermediate part reduces device complexity and assembly steps in hand-held work devices.
- Fluid-Circulation Valve Sensor Target Housing Design
A fluid circulation valve uses a separate housing with projecting reliefs to receive the magnetic sensor target.
- Flap Device Metal Sleeve Overmolding Thermal Expansion Compensation
A metal sleeve overmolded with plastic forms a flap body that ensures precise positioning and secure attachment to the drive shaft.
- Elastic Breakdown Ignition via Multipole High Frequency Discharge
Multipole high frequency discharge igniter uses in-line capacitors to produce simultaneous sparks across multiple gaps.
- Dual Valve EGR Control for Combustion Reliability
A dual valve system manages exhaust gas recirculation flow in internal combustion engines.
- Vehicle EGR Cooler Clad Tube Corrosion Protection
A vehicle cooler tube uses a clad structure with a sacrificial bonding layer to protect the core material.
- EGR Cooler Elongated Through-Hole Flow Uniformity
An elongated through-hole aligns with exhaust gas flow to distribute EGR intake uniformly across the cooler inlet area.
