Abstract
A multi-cylinder internal combustion engine is provided which includes an exhaust gas driven turbocharger. Each cylinder includes at least one inlet port controllable by an inlet valve, at least one outlet port controlled by an outlet valve, and at least one separate additional auxiliary valve arranged in the cylinder head of the engine. A line for gas flow communicates with the additional auxiliary valves. The line from the auxiliary valve of at least a first cylinder is connected directly or indirectly with at least one second cylinder, and the gas flow through that line from the first cylinder to the second cylinder is controllably guided also to a pressure storage device and/or a turbine of the turbocharger.
