Map-controlled thermostat

World’s first map-controlled thermostat for commercial vehicles

MAHLE has developed a map-controlled thermostat for commercial vehicle applications, which optimally adapts the coolant temperature to each driving situation for the first time. This increases the efficiency of the engine. Our map-controlled thermostats react very quickly and can already be actuated at low temperatures. They should be ready for series production by 2018. The technology can reduce fuel consumption in long-distance hauling applications by up to 0.5 percent. The power requirements of the cooling system are further optimized when the map-controlled thermostat works in conjunction with the controlled E-Visco® coolant pump and E-Visco® cooler. This lowers consumption and CO2 emissions can be reduced by up to two percent.
