    摘要: The present disclosure is directed to systems and methods for adjusting the operation of a gasoline-fueled engine based on monitored conditions within a combustion chamber of the engine. In some cases, the system monitors regions within the combustion chamber, identifies or determines a satisfactory condition, and applies an ionization voltage to a fuel injector to initiate a combustion event during the satisfactory condition. In some cases, the system monitors the conditions within the combustion chamber, determines a monitored condition is associated with an adjustment, and adjusts a parameters of a combustion event in order to adjust ionization levels within a combustion chamber.

    摘要: Methods and systems are provided for closed-loop adjusting a laser intensity of a laser ignition device of a hybrid vehicle. The laser intensity applied over consecutive laser ignition events is decreased until a flame quality is degraded for a threshold number of cylinder combustion events. The laser intensity is then increased to improve flame quality and the closed-loop adjustment is reiterated.

    摘要: The invention relates to a method for evaluating the state of a fuel/air mixture and/or the combustion in a combustion chamber of an internal combustion engine, with sample signals of flame light signals, preferably the flame intensity (FI), with associated mixture states being saved to a database, with flame light signals, preferably the flame light intensity (FI), of the combustion in the combustion chamber being detected and thus being compared with the saved sample signals, and with conclusions being drawn on the state of the mixture in the combustion chamber in the case of coincidence between measured and saved signal patterns. In order to enable a simple and precise monitoring of the mixture state and the combustion it is provided that a pressure measurement is also performed in the cylinder simultaneously with the detection of the flame light signals.
