摘要： The invention relates to an internal combustion engine (1), in particular in a motor vehicle, comprising at least one cylinder (3) that defines a combustion chamber (4) and in which a piston (5) can be adjusted with regard to stroke. Each cylinder (3) comprises at least one intake opening (6) for a fresh mixture. Each intake opening (6) is associated with an intake valve (7) that works together with an associated valve seat (8) in order to control the intake opening (6). At least one such intake opening (6) is provided with a guide mask (9) that laterally encloses the respective valve seat (8) on a side that is opposite the respective combustion chamber (4) along a delimited circumferential section. Each intake opening (6) is associated with an intake canal (10). In order to improve the operation of the internal combustion engine (1), at least one intake canal (10) leading to a masked intake opening (6) is associated with an additional valve (11) for controlling the intake canal (10).

摘要： A method for controlling a dethrottled internal combustion engine, which has a shared fresh gas line which supplies fresh gas to fresh gas pipes, which in turn supply fresh gas to each cylinder. The engine has at least one intake valve per cylinder, a clocked valve per fresh gas pipe for opening and closing the gas pipe and a fuel injector for each cylinder, for metered addition of fuel. The chronological location of the injection time of the fuel is adjusted for the respective cylinder as a function of a point in time of a change in the switch position of the respective clocked valve, to improve the emission values of the engine. In addition, the clocked valves are controlled so that the metered addition of fresh gas is accomplished for the respective cylinder.
