Abstract
There is described a system and method for controlling a temperature in the subchamber of a rotary engine. At least one first measurement of at least one engine operating parameter, a second measurement of the actual value of a temperature in the subchamber, and at least one third measurement of at least one aircraft operating parameter are received. A setpoint for the temperature in the subchamber is determined from the at least one first measurement and the at least one third measurement. At least one control signal is output to the engine for adjusting the actual value of the temperature in the subchamber towards the setpoint.
Claims19
A method for controlling a temperature in a pilot subchamber for pilot injection of fuel in an internal combustion engine, the method comprising:
- by a receiving a unit:
- receiving, from at least one engine sensor, at least one first measurement of at least one engine operating parameter;
- receiving, from a subchamber temperature sensor, a second measurement indicative of an actual value of the temperature in the subchamber;
- and
- receiving, from at least one aircraft sensor, at least one third measurement of at least one aircraft operating parameter;
- and
- by a processing unit:
- receiving the at least one first measurement, the second measurement, and the at least one third measurement from the receiving unit;
- determining, from the at least one first measurement and the at least one third measurement, a setpoint for the temperature in the subchamber;
- and
- outputting to the engine at least one control signal for adjusting the actual value of the temperature in the subchamber towards the setpoint.
A system for controlling a temperature in a pilot subchamber for pilot injection of fuel in an internal combustion engine, the system comprising:
- a control unit operatively coupled to the engine, the control unit comprising
- a receiving unit for
- receiving, from at least one engine sensor, at least one first measurement of at least one engine operating parameter;
- receiving, from a subchamber temperature sensor, a second measurement of an actual value of the temperature in the subchamber;
- and
- receiving, from at least one aircraft sensor, at least one third measurement of at least one aircraft operating parameter;
- and
- a processing unit for
- receiving the at least one first measurement, the second measurement, and the at least one third measurement from the receiving unit;
- determining, from the at least one first measurement and the at least one third measurement, a setpoint for the temperature in the subchamber;
- and
- outputting to the engine at least one control signal for adjusting the actual value of the temperature in the subchamber towards the setpoint.
