Abstract

An engine includes a first turbine fluidically coupled to a first group of adjacent cylinders, and a second turbine fluidically coupled to a second group of adjacent cylinders. In this engine, the cylinders of the first and second groups are arranged along a line. The engine also includes a variable valve-lift system configured to admit at least air to the first group of cylinders during reduced engine-load conditions, but to stop admitting air to the second group of cylinders during the reduced engine-load conditions.
