摘要： A catalyst control system includes a stop and start module that, during a period that the vehicle is ON between (i) a first time when the vehicle is turned ON and (i) a second time when the vehicle is next turned OFF, selectively shuts down and starts a spark ignition engine of the vehicle. A catalyst light off (CLO) control module initiates a first CLO event for a first engine startup during the period and, when a temperature of a catalyst that receives exhaust output by the engine is less than a predetermined temperature, selectively initiates a second CLO event for a second engine startup during the period. A fuel control module richens fueling of the engine during the first and second CLO events of the period. A spark control module retards spark timing of the engine during the first and second CLO events of the period.

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.

摘要： In exemplary embodiments, methods and systems are provided for controlling emissions for a drive system for a vehicle. In one embodiment, the system includes: one or more first sensors configured to measure an engine temperature pertaining to an engine of the vehicle; one or more second sensors configured to measure an ambient temperature surrounding the vehicle; one or more third sensors configured to detect an amount of running time in which the engine has been running; and a processor coupled to the one or more first sensors, the one or more second sensors, and the one or more third sensors and configured to at least facilitate controlling emissions for the drive system based on the engine temperature, the ambient temperature, and the amount of running time in which the engine has been running.

摘要： An engine control system for a vehicle includes a timer module, a stochastic pre-ignition (SPI) mitigation module, and a boost control module. The timer module tracks a period of operation of an engine where vacuum within an intake manifold is less than a first predetermined vacuum. The SPI mitigation module generates an SPI signal when the period is greater than a predetermined period and the vacuum is less than a second predetermined vacuum. The second predetermined vacuum is less than the first predetermined vacuum. The boost control module reduces output of a turbocharger in response to the generation of the SPI signal.

摘要： A system according to the principles of the present disclosure includes a vibration intensity module and a stochastic pre-ignition (SPI) detection module. The vibration intensity module determines a vibration intensity of an engine over a first engine cycle and a second engine cycle. The first engine cycle and the second engine cycle each correspond to a predetermined amount of crankshaft rotation. The SPI detection module selectively detects stochastic pre-ignition when the vibration intensity of the first engine cycle is less than a first threshold and the vibration intensity of the second engine cycle is greater than a second threshold.
