    Patent number: 7269950
    Abstract: A turbocharger comprising a turbine, director, and compressor. The turbine may be formed as a turbine wheel surrounded by at least two scrolls. The at least two scrolls may direct exhaust gases supplied thereto toward the turbine wheel to cause rotation thereof. The director may control distribution of the exhaust gases between the at least two scrolls to optimize circumferential velocity in the scroll or volute, and thus impingement velocity on the turbine. The compressor may be driven by the turbine.
