1. A method, comprising:
- causing a targeted disturbance (Δ
u) of a gas quantity (m) supplied by a gas supply to an antechamber fluidly coupled to a combustion chamber of an internal combustion engine;
measuring a change (Δ
T) resulting from the target disturbance (Δ
u) in an exhaust gas temperature (T) of an exhaust gas generated in the combustion chamber;
comparing the change (Δ
T) with a setpoint value of the change (Δ
Ttarget) of the exhaust gas temperature (T) to obtain a comparison; and
deducing the gas quantity (m) supplied by the gas supply based on the comparison.

Abstract
A method for detecting the quantity of gas (m) supplied by a gas supply device to an antechamber of an internal combustion engine. The method includes causing a targeted disturbance (Δu) of the gas quantity (m) supplied by the gas supply device, and measuring a change (ΔT) resulting from the target disturbance (Δu) in an exhaust gas temperature (T) of an exhaust gas generated in a combustion chamber connected to the antechamber. The method includes comparing the change (ΔT) with a target value of the change (ΔTtarget) of the exhaust gas temperature (T) to obtain a comparison, and deducing the gas quantity (m) supplied by the gas supply based on the comparison.

4. A method, comprising:
-
causing a targeted disturbance (Δ
u) of a quantity of gas (m) supplied to each antechamber of a plurality of antechambers of an internal combustion engine, wherein each antechamber of the plurality of antechambers is fluidly coupled to a respective gas supply of a plurality of gas supplies and a respective combustion chamber of a plurality of combustion chambers;measuring a change (Δ
T) resulting from the targeted disturbance (Δ
u) in an exhaust gas temperature (T) of an exhaust gas generated in each combustion chamber of the plurality of combustion chambers;comparing the changes (Δ
T) in the exhaust gas temperatures (T) associated with the plurality of combustion chambers to obtain a comparison; anddeducing a difference between the quantities of gas (m) supplied to the plurality of antechambers by the plurality of gas supplies based on the comparison. - View Dependent Claims (5, 6, 7, 8)

9. An internal combustion engine, comprising:
-
at least one combustion chamber; an antechamber connected to the at least one combustion chamber; a gas supply for the antechamber; a control unit configured to control the gas supply; a temperature sensor assigned to the at least one combustion chamber to measure an exhaust gas temperature (T) of an exhaust gas generated in the at least one combustion chamber, wherein the temperature sensor is connected to the control unit, wherein the control unit is designed to; cause a targeted disturbance (Δ
u) of the quantity of gas (m) supplied by the gas supply to the antechamber;measure, via the temperature sensor, a change (Δ
T) of the exhaust gas temperature (T) resulting from the targeted disturbance (Δ
u);compare the change (Δ
T) with a stored target value of the change (Δ
Ttarget) in the exhaust gas temperature (T) to obtain a comparison; anddeduce the quantity of gas (m) supplied by the gas supply based on the comparison.

10. An internal combustion engine, comprising:
-
at least two combustion chambers; at least two antechambers, each connected to one of the at least two combustion chambers; a gas supply for each of the at least two antechambers; a control unit configured to control the gas supplies; at least two temperature sensors, each assigned to one of the at least two combustion chambers and configured to measure an exhaust gas temperature (T) of an exhaust gas generated in the respective one of the at least two combustion chambers, wherein each of the at least two temperature sensors is connected to the control unit, wherein the control unit is designed to; cause, for each of the at least two antechambers, a targeted disturbance (Δ
u) of a quantity of gas (m) supplied by the gas supply;measure, via the temperature sensor assigned to each of the at least two combustion chambers, a change (Δ
T) of the exhaust gas temperature (T) of each of the at least two combustion chambers resulting from the targeted disturbance (Δ
u);compare the changes (Δ
T) of the exhaust gas temperatures (T) associated with the at least two combustion chambers to obtain a comparison; anddeduce a difference between the quantities of gas (m) supplied to the at least two antechambers based on the comparison. - View Dependent Claims (11, 12, 13)
