Nowadays, new technologies help improve the efficiency and combustion quality of engines to approach optimum level.
One key aspect here is regulating the operating temperature of the engine by means of a controlled cooling circuit to a constant optimum temperature of 110°C/230°F in all the various driving situations and engine operating states that typically occur on a day-to-day basis. Thermostats are deployed in the cooling circuit for this purpose, with significant benefits in terms of fuel consumption, exhaust emissions and engine service life.
Electronic map-controlled thermostats are the latest generation of thermostats, following on from conventional thermostats.
These units feature an electrically controlled heating element integrated in wax as an expansion material. The heating element is controlled based on a MAP sensor in the engine control unit and heats the expansion material, thereby causing the cooling circuit to open via the thermostat valve.
This allows the thermostat to impact on engine temperature much more quickly, ensuring the optimum range is maintained in the various load and operating states.
Our wire heating element is the centerpiece of the latest generation of thermostat supplied to our customers: it features very short reaction times and fast response to the heating of the expansion material.
