Dual-fuel internal combustion engine

A method for operating a dual-fuel internal combustion engine, comprising:

• supplying an amount of energy to at least two combustion chambers of the dual-fuel internal combustion engine by a gas-air mixture, wherein the at least two combustion chambers comprise a first combustion chamber positioned a first distance from at least one gas mixer configured to supply the gas-air mixture to the at least two combustion chambers and a second combustion chamber positioned a second distance from the at least one gas mixer, and wherein the first distance and the second distance are different from one another;
• and
• changing the amount of energy supplied to the at least two combustion chambers via the gas-air mixture in a first direction and changing an amount of liquid fuel supplied to the at least two combustion chambers in an opposite, second direction;
• determining a first time delay for the change in the amount of liquid fuel in the second direction for the first combustion chamber of the at least two combustion chambers based on the first distance;
• and
• determining a second time delay for the change in the amount of liquid fuel in the second direction for the second combustion chamber of the at least two combustion chambers based on the second distance, wherein the first time delay and the second time delay are different from one another.

A system, comprising:

• a first combustion chamber positioned a first distance from at least one gas mixer configured to produce a gas-air mixture;
• a second combustion chamber positioned a second distance from the at least one gas mixer, wherein the first distance and the second distance are different from one another;
• and
• a control device configured to initiate a change-over mode, wherein the control device is configured to change an amount of energy supplied to the first and second combustion chambers through the gas-air mixture in a first direction in the change-over mode, and wherein the control device is configured to change an amount of liquid fuel supplied to the first and second combustion chambers in a second direction, opposite the first direction, in the change-over mode;
• wherein the control device is configured to determine a first time delay for the change in the amount of liquid fuel in the second direction for the first combustion chamber based on the first distance, and wherein the control device is configured to determine a second time delay for the change in the amount of liquid fuel in the second direction for the second combustion chamber based on the second distance, and wherein the first time delay and the second time delay are different from one another.
