摘要： Methods and systems for optimizing fuel economy and maintaining particulate emissions below a threshold of an engine system in a vehicle. An engine system has port fuel injection, direct injection, variable compression ratio, and independent compression/expansion. A processor predicts settings for the four systems that optimize for a fuel economy that is maximized. A particulate rate of the engine system is computed based on the settings. A determination is made of whether the particulate rate is below a threshold. When the particulate rate is below the threshold, command signals are delivered to actuators of the systems to move to the settings. When the threshold is exceeded, the settings are revised to maintain the particulate below the threshold while optimizing for fuel economy.
