EXAMPLE
:
When
U v = 5 V
,
U 1
should be within
3.75 – 4.25 V
for a correct adjustment.
This adjustment is used in case of changing regulator or of an irregular functioning
during the idle motion.
For checking the contact (
drawing 7
):
- engine on contact;
- regulator at the way, supplying an
U = 5 – 6 V
and helping it by hand;
- connection of the ohmmeter according to the drawing; we measure and
R
should
be zero;
- the partial voltage in this position should be U 1 = 0.19 – 0.22 V ; in case this
condition is not fulfilled we can adjust it by the screw “
B
”.
NOTE:
The distance between the screw “3” and the axle “2” should be 1 mm at cold, in
order to avoid the idle rotation increasing when the engine is hot.
The rotation sensor is of inductive
type and consists of:
1 - Permanent magnet
2 - Insulator body
4 - Ferite core
5 - Coil
The drawing also indicates:
3 – gearbox clutch casing; 6 – flywheel
for rotation sensor.
The flywheel has
60
equidistant
teeth; there are
2
teeth missing. The
space of the remaining 58 teeth is used
to watch the rotation while the space of
the
2 missing teeth is used to watch the
reference position of the crankshaft,
corresponding to the cylinders
1
and
4
at
PMS
.
