Temperature managers—new in the MAHLE Aftermarket product portfolio A multitude of thermostats and other components for temperature regulation are added to complete the MAHLE Aftermarket product range:  Expansion elements The core of the thermostat: when heated, the expansion element (wax) expands and thus moves the piston. If the temperature drops again, it reduces in size, and a spring pushes the piston back into its starting position. Expansion elements are maintenance-free and durable. Their range of use is very versatile: actuation forces from 30 N to 2,500 N, short or long strokes, and a diversity of control ranges within the temperature span of –5°F to +265°F.  Thermostat inserts Precision at work: thermostat inserts enable the precise regulation of coolant circuits to approximately 20 m3/h in passenger cars, commercial vehicles, stationary engines, agricultural and construction machinery.  Integral thermostats The on-going development of thermostat inserts: all components such as the thermostat insert, cover, and gasket are already integrated in the integral thermostat. It can be flange-mounted directly on to the engine block.  Housing thermostats These can be fully connected with hoses or equipped with a flange and hose connectors. What sets them apart is that they consist of a combination of cover and housing, i.e. the mixing chamber is already integrated.  Map-controlled thermostats The most effective managers in the thermal system: an electrical heating resistor is integrated in the operating element’s expansion material. Consequently, these thermostats can be electrically activated, and thereby have a considerably faster effect on the engine temperature to keep the engine within the optimum range in various load and operating conditions. The result: more engine output with reduced consumption and emissions. An operating map stored in the engine control unit defines when and how heat is added.  Sleeve valve thermostats The workhorses: they regulate the cooling circuits in large engines with flow volumes starting from approximately 20 m3/h, e.g. in large passenger cars, commercial vehicles, ships, and locomotives. The sleeve valve principle allows the axial relief of the thermal expansion element and thus enables precise regulation even under heavy hydraulic loads—with a consistently high level of functional safety.  Thermal switches Provide reliable protection against engine overheating while the vehicle is stationary: thermal switches open or close the electrical circuit, e.g. on a cooling fan, at a defined coolant temperature. The thermal switches from MAHLE Aftermarket are designed for an operating voltage of up to 24 V.  Thermocouples Extremely heat-sensitive: thermocouples supply data to the electronic control unit regarding the current temperature level at various points in the engine.  Oil thermostats The oil temperature in automatic transmissions is regulated by transmission oil thermostats. This shortens the warm-up phase considerably and the transmission is subsequently kept at an ideal operating temperature. The result: reduced wear, improved gearshift comfort, and fuel savings of approximately 1% in conventional driving cycles.  EGR thermostats These regulate the flow of coolant through the EGR cooler, thus differentiating themselves from the remaining thermostats of the MAHLE Aftermarket portfolio in terms of area of application.
