Abstract
An improved turbocharged engine system comprising a piston engine with an inlet manifold, an exhaust manifold, a turbine driven by exhaust gases for transporting a portion of the exhaust gas energy to drive a compressor between a gas intake and the inlet manifold. There is used as the exhaust manifold a first exhaust manifold receiving exhaust gases only from a first set of pistons and a second exhaust manifold receiving exhaust gases only from a second set of pistons. The turbine comprises a first turbine driven by first exhaust manifold exhaust gases. The compressor comprises a first compressor driven by the first turbine. A portion of the exhaust gases from the second exhaust manifold are recycled to the inlet manifold.
