Electric Ignition Installation TRIZ Cases
- Spark Plug Access Openings in Wheel Housing Back Walls
Back-wall openings in the drive wheel housing let mechanics reach spark plugs directly, avoiding engine removal and cutting service time.
- Wheel Housing Access for Engine-In-Place Spark Plug Replacement
Openings in the wheel housing back walls let mechanics replace spark plugs without engine removal, reducing maintenance time, complexity, and cost.
- PTC Load Switching with Adaptive Current Threshold Protection
Adaptive current cutoff protects PTC load switching units from overload by using operating-parameter-based thresholds that reduce restart losses.
- PTC Load Switching with Adaptive Current Threshold Protection
Adaptive current thresholds protect PTC load switching units from overloads during startup and restart while avoiding high power loss.
- Spark Plug Electrode Gap Adjustment Device with Force Limiter
A spacer plate and force-limited stamp set spark plug electrode gaps to prevent weld damage and reduce manual adjustment time.
- Rotatable Annular Core Isolation Valve for Spark-Ignition Engines
A rotatable annular core valve isolates spark plugs from cylinder volume to prevent pre-fire events during non-ignition phases.
