Schaeffler Automotive Aftermarket is as of now, offering Ruville thermal-management modules, vacuum-controlled and electrically-controlled water pumps with all necessary mounting parts. These offer innovative aftermarket solutions for a wide range of Audi, BMW, Toyota and VW models.

 

Martyn Holt of Schaeffler explained that the Aftermarket specialists are making an important contribution when it comes to reducing CO2 emissions and fuel consumption, increasing engine life and improving climate comfort.

 

The pumping capacity of conventional water pumps used in vehicles today, often depends solely on engine speeds. High engine speeds, result in a higher coolant flow-rate, low engine speeds mean flow-rates are less. But the intelligent Ruville water-pump modules, make it possible to precisely regulate coolant temperature within the entire cooling circuit, or even to completely shut off temperature regulation if required. A diverse number of coolant circuits can be variably controlled according to specific engine requirements and this makes a significant contribution to lowering friction loss, fuel consumption and exhaust emissions.

 

The Schaeffler-developed thermal-management module, uses sensor-controlled rotary vanes to precisely regulate the temperature balance throughout the drive train.

 

In this way, up to three additional actuated coolant circuits, like the gearbox, engine oil and turbocharger, achieve optimal operating temperature quickly. The modules provide needs-based regulation of engine temperature 100 percent of the time, which has a positive effect on energy efficiency and on the life of all drive-train components. This innovative system solution includes the water pump and all mounting parts needed for replacement, and is available as a complete repair solution for 1.5 million vehicles of the Volkswagen Group worldwide.

 

Additional new products from the Ruville brand are electric water pumps for selected BMW models, as well as other vehicles. These fully-variable water pumps are not belt-driven, but operate using the vehicle's onboard 12-volt network. They operate independently of engine speeds, are energy efficient and deliver the variability needed at all times. An additional, electrically-controlled water pump for Toyota models will also be available shortly.

 

Vacuum-controlled water pumps for Audi and VW models complete the portfolio of intelligent water-pump modules from Schaeffler. These are belt-driven and controlled by negative pressure. All components in the system guarantee at all times the exact pumping capacities as specified for each engine.
