Engine Controllers TRIZ Cases
- Knock Sensor Ultrasonic Signal Extraction for Motorcycle Engine Control
A motorcycle knock sensor detects engine vibrations across audible and ultrasonic frequency ranges to identify combustion anomalies.
- Knocking Detection Using Signal Shape Analysis
Evaluating structure-borne sound signal shape distinguishes knocking from interference, reducing false-positive detections in internal combustion engines.
- Vehicle Output Control Device for Intentional Driver Actions
A vehicle output control device estimates brake operation force to manage drive power suppression.
- Carburetor Choke Valve Thermal Adjustment Mechanism
A carburetor choke valve adjusts fuel-air enrichment via a thermally responsive member, resolving starting reliability issues across varying temperatures.
- Throttle Valve Icing Detection and Removal via Torque Feedback
A throttle control apparatus uses torque feedback to detect icing on the valve.
- Capacitive Control Handles and Clutch Deceleration for Stump Cutters
A control system uses capacitive sensing to detect operator presence at stump cutter handles.
- Electronic Throttle Sealing and Bearing Design
An electronic throttle uses a sliding bearing and X-shaped sealing ring to support the shaft.
- Vent-on-Demand Fuel Sump for Vapor Management
Electronic control opens the vent valve only when fuel levels drop, removing harmful vapors while preserving system sealing integrity.
- Charge Forming Device Integrating Pressure Sensor
Integrates a pressure sensor into the charge forming device housing to eliminate separate mounting and improve measurement precision.
- Fuel Cock Link Structure for Residual Fuel Management
An integrated link structure reduces component count and weight while allowing complete fuel cutoff at the OFF position to prevent deterioration.
