Abstract
A turbocharger engine includes an engine body and a turbocharger. The turbocharger includes a large turbo unit having a large turbine chamber, a large compressor chamber, and a large turbine shaft extending between the two chambers; and a small turbo unit having a small turbine chamber, a small compressor chamber, and a small turbine shaft extending between the two chambers. The large compressor chamber is disposed upstream of the small compressor chamber in an intake passage. A large turbo axis and a small turbo axis are disposed to extend generally in the same direction as an engine output axis. The large turbo unit is disposed such that the large turbo axis is non-parallel to the engine output axis, and a large-compressor-chamber-side portion of the large turbo axis is closer to the engine output axis than a large-turbine-chamber-side portion thereof in a plan view in an axis direction of the cylinder.
