Two-mass flywheel<br />
S<strong>248</strong>_061<br />
A spring damper system within the two-mass<br />
flywheel separates the primary inertia mass from<br />
the secondary inertia mass so that the torsional<br />
vibration produced by the engine is not<br />
transmitted to the gearbox.<br />
On W engines with automatic transmission, the<br />
two-mass flywheel is substituted by a converter<br />
plate.<br />

<strong>The</strong> two-mass flywheel also serves as a sender wheel. Its job is to determine the engine speed and<br />
recognise cylinder No. 1 together with the Hall senders of the camshafts. It has a larger tooth gap which<br />
serves as a marker point. This point is registered by the engine speed sender located in the gearbox<br />
housing during each revolution of the two-mass flywheel.<br />
