Map-Controlled Thermostat

Our electrically map controlled thermostat enables additional regulation of operating temperature via maps stored in the ECU. The electronic control unit constantly compares the temperature stored on the map to the actual temperature of the engine. Map controlled engine cooling thermostat is specifically designed to achieve maximum efficiency.

How map controlled engine cooling thermostat works?
Electronic thermostat is on the basis of mechanical thermostat development and change in the case of no electricity, by the coolant temperature to open, equivalent to mechanical thermostat, working medium for paraffin.Inside the electronic thermostat, there is a thermostat heater. Before the water temperature reaches the temperature of the traditional mechanical thermostat, the heating resistance is controlled by ECM to adjust the thermostat in advance.

The automotive electronic thermostat works in the same way as the traditional thermostat under low or moderate engine load.

When the engine load is increased, energy is applied to the heating element which contacts the wax element, causing the map controlled engine cooling thermostat to open earlier to maintain the lower temperature in the coolant loop.
