摘要： In a method for reducing engine vibrations during engine braking with a malfunctioning engine brake, the engine brake includes an arrangement for altering a timing of at least one exhaust valve and an arrangement for varying an exhaust gas back pressure. The method includes detecting piston acceleration for each cylinder in the engine during the use of the engine brake, comparing the detected piston acceleration with a predetermined reference value, decreasing exhaust gas back pressure during engine braking if at least one piston is detected with a piston acceleration deviating more than a predefined amount from the predetermined reference value so that the piston acceleration will be falling within the predefined amount from the predetermined reference value.
