Abstract: A turbocharger arrangement includes a turbine housing with multiple individual cylinder exhaust delivery scrolls, each having an individual inlet to the turbine, formed therein. The turbine housing has one individual cylinder exhaust delivery scroll for each cylinder of an engine to which the turbocharger arrangement is attached. Individual runner exhaust manifolds each connect one exhaust port of one cylinder of the engine to one of the individual cylinder exhaust delivery scrolls. The individual runner exhaust manifolds may be pipes of approximately equal length and/or equal gas flow characteristics. Separating the exhaust pulses from each cylinder with individually runner exhaust manifolds and turbine scrolls allows for enthalpy in the exhaust flow to be harnessed to a greater extent, and allows the system to be tuned for optimum energy recovery from engine cylinder blowdown.
