INDUCTION COIL
The induction coil is a double-coil with stationary distribution of the voltage without
moving elements. The voltage in the secondary circuit of the coil can reach
30 KV
, the
distance between the spark plugs electrodes should be
0,8 mm
and the spark plugs wires
should have a special construction according the new concept of anti-electric interference.
When the engine is on contact the coil is supplied with a (
+ DC
) voltage; it is controlled
by the electronic control unit (
-
), as follows:
- for spark plugs
1
and
4
– pin
1
;
- for spark plugs
2
and
3
– pin
19
.
The secondary circuit is closed by the two spark plugs; the spark voltage at the cylinder
under compression is about
20 KV
; the auxiliary voltage at the cylinder under evacuation
is
250 – 300 V
, reversed polarity.
