    Abstract: 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.

    Abstract: In accordance with exemplary embodiments, methods and systems are provided for controlling fuel injection by a fuel injector of a direct injection engine. In one embodiment, a method includes: storing, in a first data storage device, a first table of values; storing, in a second data storage device, a second table of values; and adjusting, via instructions provided by a processor of the vehicle, a minimum mass value used to control the fuel injection based on an injector learned value, the first table, and the second table, wherein the injector learned value is set based on an amount of injector learning completed.

    Abstract: Methods and systems for enabling regeneration of a particulate filter of an engine system are provided. In one embodiment, a method includes: receiving, by a processor, a request for particulate filter regeneration; in response to the request, determining, by the processor, at least one of a compression ratio and an expansion ratio; generating, by the processor, control signals to actuators of the engine system to adjust the at least one of the compression ratio and the expansion ratio to achieve a desired exhaust temperature; generating, by the processor, control signals to actuators of the engine system to optimize torque output based on the desired exhaust temperature, engine speed, and a desired engine load; and initiating, by the processor, regeneration of the particulate filter based on the command signals.

    Abstract: An engine control system of a vehicle includes a starter control module and an abort module. When a clutch pedal is depressed and a user activates an ignition system, the starter control module engages a starter motor with an engine and applies current to the starter motor. The abort module selectively generates an abort signal when the clutch pedal is released. The starter control module disengages the starter motor and disables current flow to the starter motor when the abort signal is generated.
