Embodiment Construction

[0025] figure 1 A schematic block diagram of an Otto internal combustion engine, which is designed as a large gas engine and includes cylinders 10 , is shown. A mixture 11 of fuel 12 , ie gas, and combustion air 13 is supplied to the cylinder 10 for combustion of the mixture 11 , wherein the fuel 12 and the combustion air 13 are mixed in a mixer 14 .

[0026] Fuel 12 is mixed into combustion air 13 , which is compressed combustion air 13 compressed by means of an exhaust gas turbocharger 16 . The exhaust gas turbocharger 16 has a compressor 17 in which uncompressed combustion air 18 is compressed into compressed combustion air 13 , wherein the compressor of the exhaust gas turbocharger 16 17 is driven by a turbine 19 of the exhaust gas turbocharger in which exhaust gas 20 of the internal combustion engine is expanded.

[0027] As already mentioned, the fuel 12 is mixed into the compressed combustion air 13 , for which purpose at least one fuel control valve 15 is assigned to...

Abstract

Provided is a method for operating an Otto-gas engine, wherein the Otto-gas engine includes a cylinder for combustion of mixture of fuel and combustion air, an exhaust-gas turbocharger for compressing the combustion air supplied to the cylinder, and a fuel control valve for the cylinder to mix the fuel to the compressed combustion air. A control signal of the fuel control valve is determined by a first regulation and / or control device, such that the engine is operated in a preset target rotational speed and / or preset target power based on the signal and the fuel mixed with the compressed combustion air. The signal is provided to a second regulation and / or control device (22) by the first device. The second device generates a control signal for the exhaust-gas turbocharger based on the former signal such that the defined mixture of the fuel and the combustion air is provided to the cylinder (10) to operate the engine at a preset lambda value.

Description

technical field [0001] The invention relates to a method for operating an Otto internal combustion engine according to the preamble of claim 1 . Furthermore, the invention relates to an Otto internal combustion engine according to the preamble of claim 10 . Background technique [0002] Otto internal combustion engines designed as large gas engines have a plurality of cylinders for burning a mixture of fuel, ie gas and combustion air. Such large gas engines typically possess an exhaust gas turbocharger comprising a turbine and a compressor in which the hot exhaust gases of the internal combustion engine are expanded for driving the exhaust gas turbocharger compressor and thus serves to compress the combustion air to be supplied to the cylinders of the internal combustion engine. In addition, large gas engines have fuel regulating valves assigned to the cylinders of the internal combustion engine, via which fuel can be mixed with compressed combustion air in order to thus s...
