Starter element

The starter element heats the inlet air to the engine.

This element comprises three wire elements con-

nected in series and mounted in a connecting pipe,

and is located between the turbocharger and the en-

gine’s inlet manifold. The element is engaged auto-

matically when the starter key is turned to/passes the

preheating position (II). This sends a voltage pulse to

a time relay, which in turn controls engagement of

the element via a control relay. The engagement

time is approx. 50 sec.

See wiring diagrams on pages 73 and 75.
