Set of source and ignition system Vape
(technical description for service purposes)
The set contains :
-
electronic switch Z67
- ignition coil with two high voltage outlets for two plugs of two
stroke engine, controlling element of performance which governs primary coil winding
-
regulator R67 -
electronically controlled semiconduct power - rectifier , which maintains
the central value of direct-current voltage=14 V in electrical network and on battery of 12 V.
The controlling and performance circuit is built in alluminium cover serving as a cooler of
power-rectifier.
-
sensor S01 -
induct. sensor containing permanent magnet and coil with winding. The
voltage puls induce itself into coil at the moment when projection placed on outer circuit of
rotor jacket is passing the sensor core.
-
alternator A67 -
alternator is composed of stator and rotor. On stator (star-shaped form) is
placed one black coil (feeding ignition coil Z67) , 10 source coils (serving as chargers of
battery - through regulator R67 - and of lighting of motorcycle. Rotor contains 12 pcs of
permanent magnets, there are two projections on circuit determining together with sensor S01
the moment of spark flashover. The spark is generated twice to one engine revolution always
at the moment when projection is passing the
sensor core.
The mentioned system differs in concept
from existing system Vape type Z04. The coil
Z67 is based on principle of capacity , i.e.
energy for spark is obtained of condenser
discharging. The source of current for this
condenser is one black coil on alternator stator
A67, i.e. not battery 12V. This is the basic
difference when comparing with existing system
Vape Z04 where the energy source was the
battery 12V.
As there is no connection between
ignition coil Z67 and battery 12V (with
exception
to
the
connection
through
motorcycle frame), the spark will be generated
even if the battery is not mounted on
motorcycle. As regards the placement of Z67,
there is still valid the requirement of the same
building-up as for former Z04. It means to
place coil into cooling air flow and to move it
maximum away from emitted heat of cylinders
head. The advantage of coil Z67 is the
decreased heating-up when idling engine
revolutions.
Coil Z67 collaborating with rotor A67 does not enable to start up the engine on opposite
side than wished following to marked projection on outer circuit of rotor jacket and input
circuits in coil Z67.
The using of sensor S01 is very similar to that of system Z04. For the correct function it´ s
obligatory to keep the prescribed space between S01 and projection on rotor. The correct
setting-up oscillates between 0,4 - 0,5 mm. If it is not possible to maintain this spacing, we
chose as priority lower spacing (0,3 mm) than higher one.
