Abstract

An engine combustion system is disclosed which includes: a cylinder head having at least two cylinders; an exhaust duct adjoining each cylinder with the exhaust ducts of at least two cylinders converging to form an exhaust manifold within the cylinder head and two turbines arranged downstream of the exhaust manifold. In one embodiment, the two turbines are arranged in parallel with a control element disposed upstream of one of the turbines to close off flow to the one turbine. Alternatively, a first of the turbines has a first bypass duct having a first valve. Flow exiting the turbine and the bypass path converge and are provided to a second of the turbines that has a second bypass duct having a second valve. By controlling positions of each valve, flow can be provided solely to the associated turbine, the associated bypass duct, or a combination.
