METHOD FOR INITIATION CALIBRATION OF A DAMPER

摘要

The present invention relates to a method for initiating calibration of a damper (1) which is situated in a pipe (2), is connected to an engine (10) and is capable of assuming a plurality of positions between a first extreme state and a second extreme state, thereby regulating a fluid flow through the pipe (2), the first extreme state being a fully open position resulting in a maximum fluid flow in the pipe (2), and the second extreme state a fully closed position resulting in a minimum fluid flow in the pipe (2), which calibration of the damper (1) is initiated if a speed ? of the engine (10) is greater than zero, and involves the damper (1) being caused to turn to at least one of said extreme states. The invention relates also to a system, an engine system and a motor vehicle.
