Problems solved by technology

[0003] For stationary gas engines with an engine power of more than 3 MW, such gas engines are used, for example, for energy generation, the proposed regulation solution is not suitable, because of the large dimensions on the main body of these engines (for example hybrid rail ) lead to an undesirably large time delay between the control signal and its effect on the combustion process in the corresponding cylinder
Furthermore, in compounded (gemischsaufgeladen) engines the same pressure is not applied to all cylinders with the given dimensions or the pressure cannot be detected correctly due to flow effects

Embodiment Construction

[0036] figure 1 A cylinder 1 of an internal combustion engine is shown schematically with a piston 6 located therein. The introduction device 4 serves here to inject steam gas into the combustion chamber 5 . The cylinder pressure sensor 2 measures the pressure in the combustion chamber 5 of the cylinder 1 , for example continuously or discontinuously in time and / or in relation to the angle of the crankshaft (not shown here) connected to the piston 6 The data are supplied to a control or regulation device 3 for controlling or regulating the power and / or torque and / or rotational speed of the internal combustion engine. Depending on the desired control variable, a corresponding quantity of fuel for cylinder 1 is metered by control or regulating device 3 and injected into combustion chamber 5 by means of introduction device 4 . In this example, the control or regulating device 3 together with the introduction device 4 therefore assumes the role of a fuel metering device.

Abstract

The invention relates to a method for operating an internal combustion engine that has at least two cylinders (1), in particular a gas engine. According to said method, the amount of fuel supplied to each of the at least two cylinders (1) is controlled or regulated for the individual cylinders with the aid of a fuel metering device and a cylinder pressure sensor (2) in accordance with a desired performance and / or a desired torque and / or a desired speed of the internal combustion engine.

Description

technical field [0001] The invention relates to a method for operating an internal combustion engine, in particular a gas engine, having at least two cylinders. Furthermore, the invention relates to an internal combustion engine for carrying out the method in question. Background technique [0002] Methods are already known for operating internal combustion engines with a plurality of cylinders. Methods and control systems for operating internal combustion engines described in the prior art (eg DE 19621297C1, EP 1688601A2, DE 102006024956B4, DE 102007000443A1) are preferably suitable for engine control of smaller fast-burning and diesel engines, as they are used for example in passenger cars running. The examples given therein therefore generally relate to liquid fuel applications. [0003] For stationary gas engines with an engine power of more than 3 MW, which are used, for example, for energy generation, the proposed regulation solution is unsuitable because of the lar...
