摘要： A cartridge for use in a pulse energy enhanced turbine of a turbocharger. At least first and second fixed separating blades (12) are provided between a nozzle ring (6) and a disk (29), the separating blades (12) maintaining separation of exhaust gas flows through a guide grid between a divided volute and a turbine wheel (11). Exhaust pulsation energy from different cylinders or cylinder groups of an engine or engine bank are kept separated up to the turbine wheel, so that the turbine wheel reacts to individual pulses of exhaust gas flow from engine exhaust ports.
