摘要： An engine system and method for operating an engine that includes a particulate filter is described. In one example, spark delivery to one or more engine cylinders is ceased while fuel is continued to be injected to the one or more cylinders to improve particulate filter regeneration. The system and method may be particularly beneficial for direct injection turbocharged engines.

摘要： A turbocharger compressor bypass valve is disclosed. In one example, the compressor bypass valve operates inversely proportional to engine throttle operation. The approach may simplify compressor bypass valve control and reduced engine system complexity.

摘要： Methods and systems are provided for controlling a vehicle system including an engine that is selectively deactivated during engine idle-stop conditions. One example method includes, during a first condition, engaging an engine starter, without applying a starter current, to the deactivated rotating engine after the engine speed drops below a threshold speed. The method further includes, during a second condition, engaging the starter and adjusting a starter motor switch to apply a starter braking torque to the rotating engine.

摘要： A method for improving starting of an engine that may be repeatedly stopped and started is presented. In one embodiment, the method disengages a starter in response to a first predicted combustion in a cylinder of the engine. The method may reduce one-way clutch degradation of a starter. Further, the method may reduce current consumption during engine starting.

摘要： A method for improving starting of an engine that may be repeatedly stopped and started is presented. In one embodiment, the method skips combustion in at least one cylinder, according to the engine combustion order, to control engine speed when an engine is automatically restarted. The skipped combustion event may be related to a level of IMEP when combustion in a cylinder occurs under an operating condition.
摘要翻译： 提出了可重复停止和启动的用于改善发动机起动的方法。 在一个实施例中，该方法根据发动机燃烧顺序在至少一个气缸中跳过燃烧，以在发动机自动重启时控制发动机转速。 跳过的燃烧事件可能与在气缸中的燃烧在工作状态下发生的IMEP的水平有关。
