4.1.9. Subsequent cooling of the engine

The special device has temperature sensor, two reversive relays and an hour element in a carburetor support.


Temperature sensor:
  – inclusion temperature
57 °C
  – switching off temperature
52 °C
Temporary delay
12 min.


Ignition is included, electric contours are open. After switching off of ignition:

 – if temperature of the carburetor is above 57 °C, the fan is switched on and works at small speed within at most 12 minutes;
 – if temperature is below 57 °C, but will exceed this value during delay time, then the fan will be switched on for 12 minutes.

In both cases if temperature falls below 52 °C, the fan will be switched off.
