Internal Combustion Piston Engines TRIZ Cases
- Turbocharger Restricting Member Integration for Variable Nozzle Design
An integrated flange-and-pin restricting member fixes nozzle and drive-ring positions, expanding design freedom and reducing turbocharger wear.
- Fe-Oxide-Assisted κ-Phase Formation in CeO2–ZrO2 Oxygen Storage Material
Fe oxide in reduction treatment helps form the κ phase at lower temperature while limiting grain growth and preserving surface area.
- Fuel Admission Tube Mixing Openings for Gaseous-Fuel Engines
Mixing air openings in each fuel admission tube blend intake air with gaseous fuel upstream to improve ignition control.
- Engine Crankcase Ventilation Valve for Emulsion and Freeze Control
Moisture and oil in blow-by gas can freeze the valve or form emulsion; a crankcase-sandwiched valve limits exposure in engine ventilation.
- Cooperative Vehicle-Infrastructure Sensor Calibration Without Road Closures
Roadside and onboard data are matched during normal traffic to calibrate multiple sensors without closing roads or using custom targets.
- V-Type Engine Diagonal Charge Air Layout for Parts Standardization
Opposite-side charge air coolers let both cylinder banks share standardized ducts and components, reducing part diversity and material costs.
- Internal-Combustion Engine Pre-Chamber Control for Torque Conversion
An auxiliary-chamber pipe forms a pre-chamber and coordinates fuel injection with ignition to delay pressure peaks and improve engine thermal efficiency.
- Gas Injector With 3/2-Way Pilot Valve for Rapid Needle Control
At low fuel-gas pressure, a 3/2-way pilot valve coordinates hydraulic chambers to open multiple nozzle needles rapidly and uniformly.
- Multi-Label Image Classification With Visual-Semantic Contrastive Learning
Misidentified and omitted labels are addressed by combining image visual features with label semantics through contrastive learning and multi-loss training.
- Heavy-Duty Engine Heater Control for SCR Temperature Stability
An ECU adjusts supplemental exhaust heat for SCR inlet targets, balancing NOx reduction, fuel consumption, and heater degradation.
- Hierarchical Audio-Visual Feature Fusion for Complex Question Answering
Audio-visual QA struggles with complex semantics; staged fusion of audio, video, question, and answer probabilities strengthens final answers.
- Engine Aftertreatment Heat-Up Using Starter-Driven Airflow
During cold start, the engine starter pulses the engine to move exhaust-heater heat downstream without an external blower.
- Two-Stage Air-to-Air Cooler Layout for Compact Engine Intakes
A two-stage air-to-air cooler redirects charge air through different flow directions, reducing intake plumbing and liquid-cooling complexity.
- Diesel Engine Piston Bowl Vortex Wake for Heat Reduction
A stepped piston-bowl wall creates a vortex-filled wake that limits flame heat transfer without a thermal insulation coating.
- Polycarboxylic Acid–Alcohol Fuel Additive for Injector Deposit Control
A polycarboxylic acid–alcohol additive helps prevent and remove injector deposits, preserving fuel metering and combustion efficiency in high-pressure engines.
- Wall-Flow Exhaust Catalyst Layers for Heat-Resistant Purification
Regional catalyst layers with tailored pore volumes improve high-speed exhaust purification and heat resistance while reducing pressure loss.
- Cylinder Head Injection Tube with Radial Air Guidance for Fuel Mixing
A radially outward air-guiding portion creates intake turbulence, improving fuel-air mixing while preventing injection tube clogging.
- Multi-Channel Deep Weighted Aggregation for Semantic Segmentation
Three semantic channels fuse low-level, transition, and context features to balance segmentation accuracy with reasoning speed.
