Abstract

Twin turbocharger apparatus (1) comprising a first stage turbocharger (10) and a second stage turbocharger (20); comprising also a slidable piston (75) for closing or restricting an area over the second stage turbine (16) , and control means (81) which is connected to the slidable piston (75) and which is for controlling the sliding movement of the slidable piston (75) ; and the twin turbocharger apparatus (1) being such that when the slidable piston (75) is in a closed or restricted position for closing or restricting the area over the second stage turbine (16), the exhaust gases are directed to the first stage turbine (8) such that when a given boost pressure is reached on the first stage turbocharger (10) , then the slidable piston (75) operates to control the turbine speed of the first stage turbocharger (10) and to allow exhaust gases to be directed to the second stage turbine (16).
