Torque Converter - Vehicles With INGENIUM I4 2.0L Diesel Engine

Vehicles with the Ingenium I4 2.0L Diesel engine are fitted with a torque converter with a twin torsional damper and also incorporates a pendulum mass to isolate engine torsional vibrations and improve Noise, Vibration and Harshness (NVH).

The pendulum mass torque converter uses the standard spring damper system found in conventional torque converters, but has the addition of a centrifugal pendulum damper. The centrifugal pendulum damper is an arrangement of individual masses which are allowed to move within a pendulum arc motion, whilst rotating at the same speed as the turbine. The centrifugal pendulum damper is optimized to the engine forces in order to supplement the spring damper system in decoupling the engine torsional vibrations from the transmission and driveline.
