摘要： A variety of methods and arrangements for reducing noise, vibration and harshness (NVH) in a skip fire engine control system are described. In one aspect, a firing sequence is used to operate the engine in a dynamic firing level modulation manner. A smoothing torque is determined by adaptive control that is applied to a powertrain by an energy storage/release device. The smoothing torque is arranged to at least partially cancel out variation in torque generated by the firing sequence. Various methods, powertrain controllers, arrangements and computer software related to the above operations are also described.

摘要： Various methods and arrangements for determining a combustion control parameter for a working chamber in an engine are described. In one aspect, an engine controller includes a firing counter that stores a firing history for the working chamber. A combustion control module is used to determine a combustion control parameter, which is used to help manage combustion in the working chamber. The combustion control parameter is determined based at least in part on the firing history.

摘要： Methods and systems are described for detecting valve actuation faults in internal combustion engines operating in a skip fire operational mode. In one aspect, for each skip fire working cycle, an expected exhaust pressure is determined for a time period corresponding to a potential exhaust event. One or more exhaust gas pressure sensors are then used to measure an actual exhaust pressure during the potential exhaust period. The actual exhaust pressure is compared to the expected exhaust pressure to determine whether a valve actuation fault has occurred. A variety of valve actuation faults can be identified using the described approach. In some embodiments pressure sensors are deployed in the runners of the exhaust manifold.

摘要： Techniques and controllers are described for dynamically determining when to request firing decisions for individual firing opportunities while operating an internal combustion engine in a skip fire mode. In one aspect, a skip fire controller is arranged to periodically determine the timing by which a next cylinder firing decision request must be made in order to assure that a corresponding firing decision can be implemented as desired, and whether there is sufficient time to wait until at least the next periodic timing determination is made to request the next cylinder firing decision. When there is not sufficient time to wait, a firing decision request is made and the corresponding working cycle is either skipped or fired based on the received firing decision. When there is sufficient time to wait, the firing decision request is delayed until at least the next periodic timing determination is made.

In one aspect, the implementation of the start/stop feature involves automatically turning off an internal combustion engine under selected circumstances during a drive cycle. A determination is made that the engine should be restarted. During the engine startup period, the engine is operated in a skip fire manner such that a desired engine speed is reached.
