Adjust idle with the help of screw 1. The idle speed should be
800-850 rpm.
Engine rundown - checking. Using load lever 4 set the
engine speed at 3000 rpm. Release the load lever, the engine
rundown should be 2.5 - 3.5 seconds.
After returning to idle, the speed difference should not exceed
50 rpm.
WARNING. The adjustment screws for maximum fuel
feed and speed are sealed at the factory.
Exhaust emission system
Exhaust gases escape from the engine through exhaust man-
ifold 3 (Fig.9-25), front exhaust pipe (downpipe) 4, catalytic con-
verter 9, intermediate silencer 13 and front silencer 11.
There is a steel heat shield over the catalytic converter.
Exhaust gasket 1 is fitted between the downpipe flange and
exhaust manifold 1.
The downpipe is connected to the catalytic converter flange
through a moving joint. Metal/graphite ring 8 with a spherical sur-
face is placed between the flanges, an inner spherical surface is
provided in the flange of the downpipe.
The silencer pipes are held together by means of clasp 12.
Downpipe 4 is attached by three nuts to the exhaust manifold and
in addition to bracket 5.
No dismantling or repair of the silencers or pipes is possible,
have them always replaced with new ones.
Electrical system
Alternator. The Valeo alternator is supplied together with the
engine. The wiring diagram for alternator is shown in Fig.9-26.
When the ignition is switched on, the alternator «Ç» terminal
is powered through warning light 6. After the engine start current
is not supplied through the warning light and it does not illumi-
nate. The alternator «W» terminal is used for voltage supply to
electronic tachometer 4.
Starter motor.
The Valeo starter motor is supplied together
with the engine. The wiring diagram for starter motor is shown in
Fig.9-27.
Engine management system (EMS). The wiring diagram
for the engine management system is shown in Fig.9-28.
The system design, operation and diagnostics are detailed in
a separate «Peugeot» Manual for Diesel Engine Diagnostics.
Vehicle antitheft system. The vehicle VAZ-21215-10 is fit-
ted with an antitheft system of relay type (Äèë-2ê).
The antitheft system includes control module 1 (Fig.9-29),
system state indication LED 2 and code key fobs 3. The theft-
deterrent system represents an electronic control module, which
allows in case of unauthorized use to inhibit the engine start
through disconnecting the relevant electrical circuits.
Refer to Fig.9-30 for the wiring diagram of theft-deterrent sys-
tem. The installation of the antitheft system brought alterations in
operation of direction indicators and hazard flashers (Fig.9-31),
windscreen wipe/wash (Fig.9-32), rear window wipe/wash and
heating (Fig.9-33).
