Idling Devices TRIZ Cases
- Fuel Regulator Limit Cap Structure for Compact Gap Control
A grooved limit cap replaces a separate guide member to control regulator gap size, cut parts, and keep the fuel regulator compact.
- Carburettor Assembly Resistor for Preventing Idle Fuel Dripping
A fuel-passage resistor limits flow to the nozzle, keeping the check valve closed and preventing fuel dripping during engine idling.
- Single Lever Engine Control Assembly for Throttle and Choke
An integrated engine control assembly reduces operator complexity by merging throttle, choke, and shutdown controls into one intuitive lever system.
- Anti-adjusting Rotary Valve Carburetor with Eccentric Adjustment Needles
Asymmetric eccentric needle platforms paired with specialized tools prevent unauthorized adjustments, ensuring stable engine performance.
- Carburetor Fuel Metering Valve Profile for Precise Flow Control
A carburetor fuel metering valve uses a profiled sleeve and valve member to progressively vary the communication area between inlet and outlet spaces.
- Limiting Cap Inversion for Needle Valve Assembly
Inverting fixing and engagement parts eases assembly while restricting needle valve rotation.
- Carburetor Adjustment Valve Limit Cap Anti-Tamper Design
Nested limit cap with engaging grooves constrains carburetor adjustment valve rotation to prevent user tampering and exhaust regulation non-compliance.
- Carburetor Limiter Cap Tamper-Resistant Assembly
A limiter cap assembly with a clasp system secures the fuel adjustment valve to prevent unauthorized rotation.
- Carburetor Anti-Tamper Wedge Mechanism for Garden Engines
A carburetor uses micro wedge-shaped adjusting parts on idle oil and flow needles to prevent unauthorized user adjustments.
- Butterfly Throttle Valve Through Hole Prevents Carbon Deposition
A butterfly throttle valve incorporates a through hole in the second valve part to direct exhaust gas flow.
