Abstract
Official abstract text for this publication.
An internal combustion engine ( 1 ) operating in cycles, having: a plurality of piston-cylinder units ( 2 ), wherein each piston-cylinder unit ( 2 ) of the plurality of piston-cylinder units ( 2 ) is assigned an ignition device ( 3 ) which can be controlled regarding activation and selection of an ignition timing by an engine control ( 4 ), wherein a piston-cylinder unit ( 2 ), when the ignition device ( 3 ) is activated, produces a power by combustion of a gas-air mixture, which can be transmitted as a torque to a crankshaft ( 5 ) of the internal combustion engine ( 1 ) an intake stroke ( 6 ) and an exhaust stroke ( 7 ), each coupled to the plurality of piston-cylinder units ( 2 ) a supply device ( 8 ) for supplying a gas-air mixture under a boost pressure to the intake stroke ( 6 ) a signal detection device ( 9 ) for acquiring at least one signal which represents a power demand on the internal combustion engine ( 1 ) or from which a power demand on the internal combustion engine ( 1 ) can be calculated an engine control ( 4 ) for actuating actuators of the internal combustion engine ( 1 ), wherein the at least one signal can be fed to the engine control ( 4 ), and the engine control ( 4 ) is configured in a first operating mode to leave as many ignition devices ( 8 ) deactivated per cycle of the internal combustion engine in dependence on the currently present power demand, that the power of those piston-cylinder units ( 2 ), the ignition devices ( 8 ) of which are activated, results in a torque of the crankshaft ( 5 ) of the internal combustion engine ( 1 ) adapted to the currently present power demand wherein the engine control ( 4 ) is configured to, in a second operating mode, for reducing a risk of deflagration due to unburned gas-air mixture present in the exhaust stroke ( 7 ) after a first number (N 1 ) of cycles of the internal combustion engine ( 1 ), for a second number (N 2 ) of cycles of the internal combustion engine ( 1 ), to have more piston-cylinder units ( 2 ) produce power per cycle by activating the assigned ignition devices ( 8 ) than would be required for the currently present power demand after the second number (N 2 ) of cycles of the internal combustion engine ( 1 ), for a third number (N 3 ) of cycles of the internal combustion engine ( 1 ), in dependence on a currently present power demand per cycle of the internal combustion engine ( 1 ), to have so many piston-cylinder units ( 2 ) produce power by activation of the assigned ignition devices ( 8 ) that this results in a torque of the crankshaft ( 5 ) adapted to the currently present power demand.
First claim
Opening claim text (preview).
The invention claimed is: 1. An internal combustion engine operating in cycles, comprising: a plurality of piston-cylinder units, wherein each piston-cylinder unit of the plurality of piston-cylinder units is assigned an ignition device, wherein each piston-cylinder unit of the plurality of piston-cylinder units, when the ignition device is activated, is configured to combust a gas-air mixture to produce a power transmitted as a torque to a crankshaft of the internal combustion en…
