1. A supercharged applied-ignition internal combustion engine comprising:
at least one cylinder head with at least one cylinder, each cylinder having at least two inlet openings for the supply of charge air via an intake system and at least one outlet opening for the discharge of the exhaust gases via an exhaust-gas discharge system; at least one throttle flap which is arranged in the intake system; and at least one exhaust-gas turbocharger is provided, each exhaust-gas turbocharger comprising a turbine arranged in the exhaust-gas discharge system and a compressor arranged in the intake system; a knock regulator which, as output signal, provides an ignition retardation Δignition required for the prevention of knocking, and at least two at least partially variable valve drives, the valve drives having at least two valves which are movable between a valve closed position and a valve open position to open up and block the at least two inlet openings of the at least one cylinder, having valve spring means for preloading the valves in the direction of the valve closed position, and having at least two actuating devices for opening the valves counter to the preload force of the valve spring means, each actuating device comprising a cam which is arranged on a camshaft and which, as the camshaft rotates, is brought into engagement with at least one cam follower element, whereby the associated valve is actuated, and the cams of the at least two actuating devices of the at least two at least partially variable valve drives being rotatable relative to one another; and wherein the at least two valves are actuated based on a desired manifold pressure and a corrective factor based on a boost pressure. |
