摘要： A method to supply fuel to an engine of a vehicle is provided. The method includes adjusting a direct injection of fuel into a cylinder of the engine based on whether the vehicle is in a pre-delivery state. In one example, the method includes reducing an amount of fuel in a post injection to reduce cylinder bore wetting effects and lubricant dilution during the engine cold start. After pre-delivery, a normal post injection schedule may be used to reduce emissions.
摘要翻译：提供了向车辆的发动机供给燃料的方法。该方法包括基于车辆是否处于预输送状态来调节燃料直接喷射到发动机气缸中。在一个示例中，该方法包括减少后喷射中的燃料量以减少在发动机冷启动期间气缸内润湿效应和润滑剂稀释。预交货后，可以使用正常的后注射计划来减少排放。

摘要： A method to supply fuel to an engine of a vehicle is provided. The method includes adjusting a direct injection of fuel into a cylinder of the engine based on whether the vehicle is in a pre-delivery state. In one example, the method includes reducing an amount of fuel in a post injection. In other examples, the method includes changing a timing of a post injection. In still other examples, the method includes changing an amount and/or a timing of a main injection of fuel, or suppressing a post injection. By using a modified post injection schedule during pre-delivery, cylinder bore wetting effects may be reduced. After pre-delivery, a normal post injection schedule may be used to reduce emissions. Pre-delivery may be identified in a variety of ways: based on a number of miles driven, a maximum vehicle speed, an engine run time, or combinations thereof, as examples. Further, a vehicle retailer may actuate a delivery-indicating signal once the vehicle has been delivered.

摘要： A method is provided for controlling EGR flow in turbocharged engine. The method comprises operating a low-pressure exhaust gas recirculation (LP-EGR) system at a fixed EGR percentage rate of fresh airflow from mid-load down to a minimum engine load, even as load changes. In this way, errors in the delivered LP-EGR rate during transient conditions may be alleviated by providing a fixed EGR percentage of fresh airflow at all engine loads within a fixed mode range.
