Abstract
A method includes operating an air boosting apparatus of a two-stroke, opposed piston engine as a function of one or more factors including a first engine speed, a first torque, demand, a first altitude, a first transient rate, and one or more first ambient conditions to provide a first pressure S ratio (PR} of pre-turbine pressure (PTP) versus turbocharger compressor discharge pressure (CDP} and a first air-to-fuel ratio (AFR).
