INTERNAL COMBUSTION ENGINE WITH MULTIPLE TURBOCHARGER CYLINDERS WITH EXHAUST GAS REINJECTION AND METHOD FOR OPERATING SUCH AN INTERNAL COMBUSTION ENGINE

摘要

The air intake (31) and exhaust gas (39) valves of the exhaust gas preparation cylinder (8) during an up stroke of the driven piston of the preparation cylinder (8) are each time partially opened by the control (51) and a second lubricating oil circuit (50) is provided for the cylinder for preparing the exhaust gases (8), and method for operating the combustion engine internal characterized in that the expulsion of gases from the preparation cylinder (8) takes place through the air intake valve (31) in the air supply system (9-17) and supply of water from the exhaust gas preparation cylinder (8) to the second lubricating oil circuit (50).
