New Engine Cooling Systems for Hybrid Vehicles from Schaeffler

Schaeffler, one of the leading global suppliers of the automotive and industrial sectors, meets the increasing need for engine cooling in hybrid vehicles with its new start-stop system thermally managed water pumps. The pump's "split cooling" concept allows the lower circuit temperatures in the motor to be controlled. With these new repair solutions, it is aimed to reach the product range covering more than two million vehicles.

The Automotive Aftermarket division of Schaeffler, one of the leading global suppliers to the automotive and industrial sectors, is expanding its range of thermally managed water pumps under the INA brand. Schaeffler has supplied parts to many vehicles since its first generation thermally managed water pump modules were launched in 2011. Through close partnerships with automotive manufacturers, Schaeffler develops thermally managed water pump modules that can control the coolant temperature in different cooling circuits. Thus, the vehicle's engine reaches its optimum operating temperature faster. In addition to increasing driving comfort, the system also provides a reduction in fuel consumption and CO2 emissions. Continuously developed over the years, the second generation modules are sold exclusively by Schaeffler on the independent automotive aftermarket as a complete repair solution.

Second generation thermally managed water pump modules

The second generation of thermally managed water pump modules still use rotary slide valves that control the coolant flow according to the driving situation. However, thanks to the new control concept with two independent rotary slide valves, the functionality of the product is greatly increased. One valve sends coolant to and from the radiator, while the other separates the engine cooling circuits in the cylinder head and engine block. Thus, the system called “split cooling” emerges.

The new start-stop system concept meets the increased performance requirements in hybrid vehicles, while providing optimal control of cylinder head and engine block temperatures with targeted cooling. When exiting the electric-only mode or when the waiting time between cycles increases in start-stop vehicles, the friction force in the combustion chambers is greatly reduced. In this way, wear and CO2 emissions are reduced while achieving the best combustion performance.

Maik Evers, Product Management Manager of Schaeffler Automotive Aftermarket Division; “Thermal-managed water pumps play a major role in improving the energy efficiency of vehicles and reducing CO2 emissions. High-precision and intelligent control of increasingly complex cooling and heating circuits ensures that all systems in vehicles are zamIt ensures that it works in the best temperature range. In this way, the service life of the parts is extended and the environment is protected. In parallel with the growth in our global vehicle range, we are constantly expanding our thermally managed water pump product range. We are proud to be the first supplier to offer this repair solution for hybrid vehicles in the independent automotive aftermarket.” said.

The range is expanding: repair solutions for BMW and MINI

Schaeffler, which previously supplied thermally managed water pump modules for VW Group vehicles only in the independent automotive aftermarket, has expanded its product range to include two part numbers for BMW and MINI engines. Two new thermally managed water pump modules are available for use in BMW and MINI vehicles, part numbers 538 0811 10 (left) and 538 0810 10 (right). These two parts fit into a broad product portfolio that covers more than two million vehicles and is expected to double over the next three years.
