Abstract

A method of implementing start-stop in an internal combustion engine, the engine having exhaust gas recirculation (EGR) from at least one dedicated EGR (D-EGR) cylinder. For stopping the engine, the camshaft is locked, and a hydraulic cam phaser is used to cushion the engine inertia. The engine is stopped such that one of the D-EGR cylinders is in top-dead center position. For starting the engine, that D-EGR cylinder is fuel-injected, and exhaust bleed-off performed if necessary.
