Thus, it enables the vehicle to come back into a end without the need of stalling the engine. Additionally, it provides a variable level of torque multiplication at small engine speeds. So, it improves the breakaway acceleration. A fluid coupling operates very well when both the impeller and turbine rotate at the exact same speeds. Nevertheless, it is rather inefficient within the First acceleration, where rotational speeds are rather distinctive.
