Each individual line supplies fresh air to one combustion chamber. Each cylinder has one intake valve. An additional valve is provided in each individual line upstream from the intake valve for opening and closing the individual line.The fresh gas system is characterized in that the collecting line is unthrottled and a control unit for actuation of the additional valves is designed so that it subdivides a fresh gas charge of the combustion chamber which depends on the load state into two charging phases (A, B) within an intake time window (T) limited by the opening and closing of the intake valve such that it actuates the additional valve to close within the intake time window (T) at a closing point in (TS) that depends on the load state and then actuates it to open at a later opening point in time (TO) that depends on the load state of the piston engine.

摘要： The present invention relates to an operating method for a piston engine (1), in particular in a motor vehicle. The piston engine comprises a plurality of cylinders (6) having intake valves (9), exhaust valves (10), combustion chambers (7), and pistons (8); a fresh gas system (2) that contains an extra valve (13) assigned to the cylinders (6), a fuel system (5) and an exhaust system (4).To improve the smooth running of the piston engine (1), a fuel/fresh gas ratio in the exhaust gas is measured selectively for each cylinder in the exhaust system (4). The fuel system (5) is operated in such a way that it supplies the same amount of fuel to all combustion chambers (7) in steady-state operation of the piston engine (1). The extra valve (13) is operated in such a way that the quantity of fresh gas supplied to the combustion chambers (7) in steady-state operation is adjusted selectively for each cylinder as a function of the measured fuel/fresh gas ratio to achieve a target value for the fuel/fresh gas ratio that is the same for all cylinders (6).
