A frequency piece with built-in lubricant storage shifts steering column resonance, cuts tolerance noise, and avoids relubrication.
An electrical actuator oscillates the crankshaft to purge combustion gases and start the engine with a smaller starting system.
A flywheel starter pulley retainer with a fin portion couples the pulley to the flywheel, reducing assembly time compared to traditional fasteners.
A fuel enrichment simple starting device injects concentrated fuel into a carburetor mixing room via positive pressure vibration.
A valve stem with a sodium-filled thermal cavity directs heat away from the combustion chamber, while a thermal barrier prevents overheating of the upper stem.
Arc-shaped rope outlet opening guides starter rope through deflection roller, eliminating complex rotary bearings and reducing starting resistance.
A recoil starter dust cover uses concentric circular uneven portions to form a nest structure with the rope reel.
Segmented rope reel with spiral spring reduces user pulling force, enabling compact engine cover design and improved startability.
A marine drive recoil starter handle moves to an offset position, allowing the second cowl portion to swing freely without interference.
A single rotary dial manipulates fuel valve, choke, and ignition system positions to simplify engine operation.
An engine start control system detects maximum intake pipe pressure during manual cranking to estimate atmospheric conditions.
Positioning the texture boundary within the sliding movement area avoids intense stress at the neck portion while maintaining high-temperature creep resistance.
Tubular spring guide supports outer valve spring periphery to prevent lateral deformation during high-speed operation.
A quick-start extension on a chainsaw crankshaft engages with a portable drill socket, replacing manual pullcord effort to start cold engines.
A magneto timing control system adjusts belt tension to set ignition advance and retard.
A pump pressurizes an inflatable bladder inside a fuel tank filler neck to displace fuel and prime the system without draining the battery.
