The innovative thermal management module from Schaeffler reduces fuel consumption and CO2 emissions by up to four percent.
The temperature of the motor, turbocharger and transmission as well as the interior can be precisely controlled with the thermal management module.
Rotary slide valves controlled by sensors enable the ideal temperature window for the engine and transmission to be reached quickly.

Schaeffler is helping to unlock new potential through the optimization of internal combustion engines with the new thermal management module. This innovative module is the key to reducing fuel consumption and CO2 emissions by up to four percent.
The thermal management module is a temperature control unit for the entire drive train. It is integrated in a compact component manufactured from high-strength plastic and combines numerous functions. Where as engine temperature has been controlled until now in a rudimentary manner by a thermostat located close to the engine, the new modern thermal management module controls the temperature conditions in the vehicle precisely and enables operation in the optimal temperature window in the fastest possible time. This means on the one hand that the cold running phase is significantly reduced by completely blocking off the cooling jacket. On the other hand, the individual components can be operated at higher temperatures than would be possible with a system controlled by a thermostat. The engine temperature can also be reduced under full load and the tendency for knocking and enrichment of the mixture under full load can be reduced.
The opportunities for precisely controlling temperature in order to increase efficiency range from both the engine and heating to the transmission and turbocharger. Controlling the temperature of alternators, hybrid modules and batteries is one of a range of possible tasks that can be performed by this sensor controlled component – they can be efficiently cooled and heated according to requirements using the thermal management module from Schaeffler.
Precise control by means of a rotary slide valve enables the ideal temperature window for the engine and transmission to be reached rapidly. This has an effect on both the energy efficiency and the life of components in the drive chain. The turbocharger can also be included in the components whose temperature is controlled by the thermal management module. Individual control ensures aftercooling of the thermally stressed exhaust gas turbine.
“The performance of the thermal management module makes this component particularly suitable for use in engines for start-stop operation“, says Prof. Peter Pleus, Member of the Executive Board Engine Systems. The individual components of the module are also optimized for friction in accordance with Schaeffler’s high requirements in terms of energy efficiency. This means that the thermal management module can be connected directly to the engine control unit without additional power stages thanks to its low power consumption.
The thermal management module also releases developers from the constraint of having to fit the component in close proximity to the engine block – as was always the case with a thermostat located on the engine. Standardized, non-interchangeable hoses reduce assembly times and ensure a high level of seal integrity. This means that Schaeffler’s thermal management module makes a valuable contribution to quality.
