Abstract
In a method for operating a combustion engine in which exhaust gas located in a cylinder during an outlet cycle thereof is ejected from the cylinder and supplied to an exhaust system, a particularly high specific power output of the combustion engine and/or a particularly low specific fuel consumption are to be made possible, in a particularly simple and reliable manner. For this purpose, according to the invention, in a first cycle phase of the outlet cycle the pulse of the exhaust gas pressure wave flowing out of the cylinder is transmitted in whole or in part to the primary side of an exhaust gas charge pump, before the exhaust gas is passed to the exhaust system in a second cycle phase of the outlet cycle.

Method for operating a combustion engine in which exhaust gas located under pressure in a cylinder during an outlet cycle thereof is ejected from the cylinder and supplied to an exhaust system, wherein in a first cycle phase of the outlet cycle the pulse of the exhaust gas pressure wave flowing out of the cylinder is transmitted in whole or in part to the primary side of an exhaust gas charge pump, before the exhaust gas is passed to the exhaust system (12) in a second cycle phase of the outlet cycle.
Combustion engine comprising a number of cylinders in each of which a working piston, acting on a shared crankshaft, is guided, the combustion chamber of the or each cylinder being connected to a gas inlet system via an actuable inlet valve system on the inlet side and both to an exhaust system and to the primary side of an exhaust gas charge pump via an actuable outlet valve system via a pulse switch on the outlet side.
