Abstract
A method of recycling exhaust gas of a multi-cylinder reciprocating internal combustion engine with an exhaust turbocharger operates without EGR flutter valves and also reduces the amount of designed complexity for the entire EGR design. Exhaust gas recycling is only permitted in the system during certain phases of operation of the internal combustion engine. Only the exhaust gas expelled from one cylinder of a cylinder row is completely or partially recycled at a preset exhaust gas recycling rate via the exhaust gas recycling duct to the blowing air manifold duct, while such exhaust gas recycling is prevented between such exhaust gas recycling phases of operation. The exhaust gas expelled from the cylinder or cylinders is also fed to the exhaust gas turbocharger via the gas manifold duct.
