Tenneco Inc.’s Continuously Controlled Electronic Suspension (CES) technology will be introduced to the North American aftermarket in January through the company’s new Monroe OESpectrum line of replacement shock absorbers and struts. Tenneco will offer six OESpectrum replacement electronic dampers for a variety of Volvo models equipped with the sophisticated original equipment system. Now featured on several Volvo applications as well as the Mercedes-Benz C-Class sedan, the CES system continuously adjusts damping levels according to road conditions and vehicle dynamics. At the heart of the system is an electronic control unit (ECU) that processes driver inputs and data from sensors placed at key locations on the vehicle. The ECU utilizes control software that processes this information in real time and sends signals to instantaneously adjust the damping level of each shock absorber valve, to help ensure superior ride comfort and firm vehicle control. The new Monroe OESpectrum replacement electronic dampers will be available for Volvo V60, V70, V80, and XC70 applications equipped with the electronic adjustable suspension feature.
