Thermostats
Thermostats
- The thermostat controls the engine’s temperature by adjusting the coolant flow towards the radiator.
- It helps the engine quickly reach the ideal operating temperature.
- The thermostat keeps the engine’s temperature within normal operation values throughout the year, regardless of the outside temperature.
- It prevents excessive fuel consumption.
- It increases the life-cycle of the engine.
- It reduces the emission of pollutant gases.
Operating Principal:
The thermostat is made up of a DILATANT ELEMENT working as a temperature sensor and actuator, transforming heat energy of the coolant into mechanical energy, creating the displacement of the central axis in order to achieve the opening of the main valve.
Upon the decrease of the coolant temperature, the main valve returns to the closed position because of an adjusted spring action in the direction opposite to the opening of the valve.
Factors reducing the need to replace thermostats:
- Frequent coolant replacement, at least once a year.
- Using the manufacturer’s recommended coolant.
- Removing air bubbles inside the circuit, after replacing some element inside it.
- Using the correct thermostat that meets the relevant applications requirements.
