  • Patent number: 10202927
    Abstract: Methods and systems for controlling combustion performance of an engine during recompression HCCI combustion are provided. The method includes regulating a valve actuation timing and a fuel injection timing to cause a combustion phasing of at least one cylinder of the engine to approach a target combustion phasing, and estimating current combustion state information based on the combustion phasing. The current combustion state information includes at least one of a temperature, a pressure, and a pre-combustion charge composition associated with the at least one cylinder. The method further includes determining a target fuel injection amount, and determining whether the target fuel injection amount would require actuator settings that violate predetermined constraints in order to cause the combustion phasing to approach the target combustion phasing. A fuel injection amount is adjusted when the target fuel injection amount would require actuator settings that violate the predetermined constraints.

  • Patent number: 9708991
    Abstract: Systems and methods are described for on-line, real-time estimation of a residual mass in an engine cylinder during HCCI combustion. The residual mass is estimated based on an estimated residual mass for a previous combustion cycle. A value of a first performance variable for the first combustion cycle is determined based only on engine data measured by one or more sensors. A value of a second performance is estimated based at least in part on the estimated residual mass for the first combustion cycle. An adaptive scaling factor is determining for the first combustion cycle based on the determined value of the first performance variable and the estimated value of the second performance variable. An adjusted residual mass for the first combustion cycle is then determined based on the estimated residual mass for the first combustion cycle and the adaptive scaling factor for the first combustion cycle.

  • Patent number: 9429096
    Abstract: Methods and systems are provided for controlling a vehicle engine to reduce cycle-to-cycle combustion variation. A predictive model is applied to predict cycle-to-cycle combustion behavior of an engine based on observed engine performance variables. Conditions are identified, based on the predicted cycle-to-cycle combustion behavior, that indicate high cycle-to-cycle combustion variation. Corrective measures are then applied to prevent the predicted high cycle-to-cycle combustion variation.

  • Patent number: 9376979
    Abstract: Methods and systems for controlling combustion performance of an engine are provided. A desired fuel quantity for a first combustion cycle is determined. One or more engine actuator settings are identified that would be required during a subsequent combustion cycle to cause the engine to approach a target combustion phasing. If the identified actuator settings are within a defined acceptable operating range, the desired fuel quantity is injected during the first combustion cycle. If not, an attenuated fuel quantity is determined and the attenuated fuel quantity is injected during the first combustion cycle.

  • Patent number: 9334818
    Abstract: Methods and systems are described for controlling engine combustion during a mixed-mode combustion modality. A target exhaust valve timing is determined based on a first combination of engine speed and load. An amount of trapped residual in an engine cylinder after an exhaust valve is closed during a first combustion cycle is also determined. Based at least in part on the amount of trapped residual, an amount of gas that will be drawn into the engine cylinder when the intake valve is opened during a second combustion cycle is determined. The target exhaust valve timing is then adjusted during the second combustion cycle in order to adjust the amount of gas that will be drawn into the engine cylinder when the intake valve is opened during a third combustion cycle.

  • Patent number: 9228527
    Abstract: Methods and systems are provided for estimating engine performance information for a combustion cycle of an internal combustion engine. Estimated performance information for a previous combustion cycle is retrieved from memory. The estimated performance information includes an estimated value of at least one engine performance variable. Actuator settings applied to engine actuators are also received. The performance information for the current combustion cycle is then estimated based, at least in part, on the estimated performance information for the previous combustion cycle and the actuator settings applied during the previous combustion cycle. The estimated performance information for the current combustion cycle is then stored to the memory to be used in estimating performance information for a subsequent combustion cycle.
