Noise emissions and thermal insulation
A.4.5 Insulation for cold climates
The insulation on vehicles intended for cold climates must guarantee that the temperature of the engine cooling water does
not drop below 80ºC during constant running.
The thermostat fitted in the circuit ensures correct engine operation if the opening temperature is 68
±
2. ˚ C
If, despite the insulation, the engine runs at less than 80ºC and the temperature of the water reaching the heater is not sufficiently
hot enough, then it is necessary to install a pre-heater capable of providing at least 25000 kCal/h.
The pre-heater becomes compulsory when the vehicle operates routinely at temperatures below 0ºC.
Having defined the insulation for the engine, it is necessary to measure its efficacy by testing the capacity of the cooling system and
the capacity of the heating system.
After the tests it may be necessary to complete preparation by:
- increasing the power or the insulation if the heating test temperatures are low;
- increasing the air passage and reducing the insulation if the temperatures obtained in the cooling test are too high.
It is recommended that IVECO be informed of the results obtained and consultancy be sought regarding any modifications for fine
tuning.
