Abstract
A method for detecting the quantity of gas (m) which is supplied by means of a gas supply device to an antechamber of an internal combustion engine, whereby a targeted disturbance (Δu) of the gas quantity (m) supplied by the gas supply device is performed and 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 is measured, whereby, by comparison with a target value of the change (ΔTtarget) of the exhaust gas temperature (T), the gas quantity (m) supplied by means of the gas supply device is deduced.

A method for detecting the quantity of gas (m) which is supplied by means of a gas supply device to an antechamber of an internal combustion engine, wherein a targeted disturbance (Δu) of the gas quantity (m) supplied by the gas supply device is performed and 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 is measured, whereby, by comparison with a setpoint value of the change (ΔTtarget) of the exhaust gas temperature (T), the gas quantity (m) supplied by means of the gas supply device is deduced.
Method for detecting the quantity of gas (m) which is supplied to at least two antechambers of an internal combustion engine by means of associated gas supply devices, wherein a targeted disturbance (Δu) of the supplied quantity of gas (m) is performed, and individually for combustion chambers connected to at least two antechambers, a change (ΔT) of an exhaust gas temperature (T) of an exhaust gas resulting from the targeted disturbance (Δu) is measured, whereby, by comparing the resulting changes (ΔT) in the exhaust gas temperatures (T), a difference between the quantities of gas (m) supplied by means of the different gas supply devices is deduced.
Method for equalization of the quantity of gas (m) which is supplied to at least two antechambers of an internal combustion engine by means of associated gas supply devices, wherein a targeted disturbance (Δu) of the supplied quantity of gas (m) is performed, and individually for combustion chambers connected to at least two antechambers, a change (ΔT) of an exhaust gas temperature (T) of an exhaust gas resulting from the targeted disturbance (Δu) is measured, whereby, by comparing the resulting changes (ΔT) in the exhaust gas temperatures (T), a difference is determined and an actuation of at least one of the at least two antechambers occurs such that the difference disappears.
An internal combustion engine with:
- at least one combustion chamber
- an antechamber connected to the at least one combustion chamber
- a gas supply device for the antechamber
- a control unit for controlling the gas supply device,
- 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, whereby the temperature sensor is connected to the control unit, wherein the control unit is designed to
- perform a targeted disturbance (Δu) of the quantity of gas (m) supplied by means of the gas supply device and
- by means of the temperature sensor, to measure a change (ΔT) of the exhaust gas temperature (T) resulting from the targeted disturbance (Δu), and
- by comparison with a stored target value of the change (ΔTtarget) in the exhaust gas temperature (T), to deduce the quantity of gas (m) supplied by means of the gas supply device.
An internal combustion engine with:
- at least two combustion chambers
- at least two antechambers which are each connected to one of the at least two combustion chambers
- a gas supply device for each of the at least two antechambers
- a control unit for controlling the gas supply devices,
- at least two temperature sensors which are each assigned to one of the at least two combustion chambers, to measure an exhaust gas temperature (T) of an exhaust gas generated in the at least one combustion chamber, whereby each temperature sensor is connected to the control unit, wherein the control unit is designed
- to perform, for each of the at least two antechambers, a targeted disturbance (Δu) of the quantity of gas (m) supplied by means of each gas supply device, and
- by means of the assigned temperature sensor, to measure a change (ΔT) of the exhaust gas temperature (T) of each combustion chamber resulting from the targeted disturbance (Δu), and
- by comparison of the resulting changes (ΔT) of the exhaust gas temperatures (T), to calculate a difference.
