摘要： Turbocharged engine water vapor ingestion control techniques determine a dew point of a charge air cooler (CAC) in an induction system of the engine based on measured humidity and temperature of a mixture of (i) air drawn into the induction system and (ii) exhaust gas produced by the engine that is cooled and recirculated by a low pressure cooled exhaust gas recirculation (LPCEGR) system of the engine back into the induction system. When the mixture temperature is less than the CAC dew point, a condensate accumulation in the CAC is determined. When the CAC condensate accumulation does not satisfy a set of one or more thresholds, the mixture temperature is increased. When the CAC condensate accumulation satisfies the set of one or more thresholds, an amount of the exhaust gas that is cooled and recirculated by the LPCEGR system is decreased until the mixture temperature meets the CAC dew point.

摘要： An ignition control system and method for an engine having a two-step variable valve lift (VVL) system utilizes an ignition control system comprising a plurality of spark plugs each configured to generate one or more ignition strikes during a combustion event in a respective cylinder of the engine and a controller configured to detect a low-to-high or high-to-low lift mode transition of the VVL system and, in response to detecting the low-to-high or high-to-low lift mode transition of the VVL system, command the ignition control system to perform multi-strike ignition for at least one combustion event, wherein commanding the multi-strike ignition mitigates or eliminates at least one of engine torque variations and increased engine emissions resulting from poor combustion quality caused by residual exhaust components within the cylinder from a previous combustion event prior to the low-to-high or high-to-low lift mode transition of the VVL system.

摘要： A method, computer program product and system for detecting that a functional model execution is out-of-order with respect to a target execution. A value of a store instruction to be stored in a memory address, where the store instruction is executed by the functional model, is received by the timing model. This value is stored by the timing model in a target oracle memory at a time when the target system would execute the store instruction. The timing model compares the value in the target oracle memory with the value of a load instruction to be loaded from the same memory address, which is received from the functional model, at a time when the target system would execute the load instruction. The timing model detects an out-of-order instruction stream with respect to the target instruction stream if there is a miscomparison.

摘要： Charging control techniques for a vehicle including an engine that drives an alternator configured to charge a battery of the vehicle comprise modeling a fuel consumption of the alternator for each load level across a range of alternator loads using an engine torque model and a set of operating parameters of the engine, determining an energy output from the alternator for each load level across the range of alternator loads, calculating a cost-to-charge metric based on the modeled alternator fuel consumption and the determined alternator energy output for each duty cycle across a range of duty cycles of the alternator, determining an optimal cost-to-charge from the calculated cost-to-charge metrics, determining a target cost-to-charge metric based on a state of charge of the battery, and operating the alternator accordingly at an optimal duty cycle based on the metrics and current engine operating conditions.

摘要： A computer-implemented method for generating pre-purchasing confidence recommendations. A browser widget scans post-sale activities of a user and searches for product-specific parameters of items from the scanned purchase records. A system stores the searched product-specific parameters and the post-sale activities in a data storage. The browser widget monitors purchasing activities of the user, and in response to the monitoring, retrieving, relevant product-specific parameters and the post-sale activities matching to the monitored purchasing activities. Based on the retrieving, generating a pre-purchasing confidence recommendation to the user before completion of a purchase by the user.
