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.

Claim (Index 7):
An improved internal combustion engine, the engine having at least a number of cylinders having pistons and valves, a camshaft for actuating valves of the cylinders, comprising:\n at least one cylinder operable as a dedicated exhaust gas recirculation (D-EGR) cylinder, with the other cylinders being main cylinders; a locking pin, operable to lock the camshaft in a position such that the engine stops at a top-dead center (TDC) position of one of the D-EGR cylinders; a hydraulic cam phaser operable to cushion the stop of the engine when the camshaft is locked; and a control unit programmed to receive engine stop data and to send a control signal to the locking pin in response to the engine stop data; and wherein the control unit is further programmed to receive engine start data and to deliver a control signal to the fuel injector of the D-EGR signal in response to the engine start data and to re-start the engine.
