ECI ignition module, left cylinder bank An L/C/R coil/condenser/resistance) - oscillating circuit with control and regulating circuit generates a 180 volt AC voltage (primary voltage) for every spark plug.

Disconnect electrical connector (2) at ECI ignition system power pack (N91). After ignition is turned OFF, only disconnect the plug on the ECI power pack after first waiting for 3 minutes.

Ignition map in the ME control unit. ECI. 1. Generation of the ignition voltage (ac voltage). There is an output stage for each spark plug in the ignition modules. The ignition coils are arranged in the spark plug connectors. The output stages with oscillating circuit generate the ignition voltage from an input of about 180 V.

Feb 23, 2016 · Check the corresponding ECI ignition module (battery voltage, ground, auxiliary voltage 23 V, voltage 180 V and lines for ion current signal with ground line for discontinuity).

The short name for the AC ignition system ECI means: E = Energy (energy) C = Controlled (controlled) I = Ignition (ignition system) The ignition system ECI must initiate combustion by creating a spark at the spark plugs.

Sep 3, 2016 · A technical documentation on the ECI ignition system for various Mercedes-Benz models. It details the ignition coil power transistor, including schematics and tables that describe the ignition trigger signals and voltages for different cylinders.

Remove plug from ECI power pack unit only after first waiting for 3 minutes. The voltage is then no longer dangerous because the capacitor has had time to discharge.

"danger!high tension!". In german, english, and french. Bonded to cover. Cylinder head cover, left. Validity: This part is valid if at least one of the following applies. - With V

Detects the engine loading which depends on the throttle valve position and the charge pressure.
