Application
Engines
- TU
- EW
Injection system: SAGEM S2000 PM1
Flow chart
"A" assembly: EW engine
"B" assembly: TU engine
(1) engine speed sensor (1313)
(2) (1320) injection ECU
(3) ignition coil unit (1135)
(4) camshaft position sensor (1115)
(5) ignition coil unit with phase detector (1191)
Compact coil housing (1135)
Application: EW engine
The coils are attached to a compact box located and fastened on the cylinder head
"double computer-coil" ignition: 2 sparks occur, one at the end of the compression stroke, the other during the exhaust phase (wasted spark)
Ignition coil unit with phase detector (1135)
Application: TU engine
The coils are attached to a compact box located and fastened on the cylinder head
"double computer-coil" ignition: 2 sparks occur, one at the end of the compression stroke, the other during the exhaust phase (wasted spark)
A system incorporated in the compact coil unit permits the injection ECU to detect the position of piston No. 1
NoteThis system replaces the camshaft position sensor
Sparking plugs
Special features
- Flat seat ignition plugs
- Tightening torque: 2,5 daNm
Injection ECU (1320)
The coil command and power stages are incorporated into the ECU (there is no external ignition module)
The ECU supplies each of the 2 coil primaries
EW engine
The synchronisation of ignition is achieved by the sensor of the N°1 reference cylinder (camshaft position sensor (1115))
TU engine
The synchronisation of ignition is achieved by the phase detector incorporated in the compact coil unit
On board diagnostic system (EOBD)
