STARTER SYSTEM
CS-310
7
Working principle
1. When starter grip (J) is pulled, rope reel (D)
rotates.
2. The rotation force of rope reel (D) is transmitted
to pawl catcher (F) by power spring (E).
3. Pawl catcher (F) engages with starter pawls on
fl ywheel to turn crankshaft.
4. The load from compression pressure in cylinder
will keep crankshaft from rotating as power spring
(E) is twisted and accumulates energy.
5. As starter grip is pulled further, more energy is
stored in power spring (E) until accumulated energy
is enough to overcome compression pressure in
cylinder.
6. When accumulated energy in power spring (E)
overcomes the load from compression pressure in
cylinder, crankshaft is rotated.
7. Power spring absorbs compression resistance of
cylinder and snatch back of engine during starting
action.
8. When starter rope is released, rope reel (D) is
returned together with power spring (E) and pawl
catcher (F) by rewind spring tension.
9. After engine starts, starter pawls pivot outward by
centrifugal force and disengage from pawl catcher
(F).
