Control system for an engine cylinder with fuel control of pre chamber and main chamber
A control system for an engine cylinder having a pre-chamber and a main chamber includes a pressure sensor being provided in the pre-chamber, and a processor coupled to the pressure sensor. The processor is configured to measure pre-chamber pressure using the pressure sensor, determine a peak pre-ch...

| description | A control system for an engine cylinder having a pre-chamber and a main chamber includes a pressure sensor being provided in the pre-chamber, and a processor coupled to the pressure sensor. The processor is configured to measure pre-chamber pressure using the pressure sensor, determine a peak pre-chamber pressure from the measured pre-chamber pressure, calculate an estimated main chamber pressure corresponding to the peak pre-chamber pressure from at least one cylinder condition at ignition, calculate a pressure ratio of the peak pre-chamber pressure to the estimated main chamber pressure, calculate a fuel parameter for at least one of the pre-chamber and main chamber from the pressure ratio to achieve a desired pressure ratio, and generate a control signal to provide fuel to at least one of the pre-chamber and main chamber in accordance with the fuel parameter. |
