    摘要： The present invention describes a fuel-management system for minimizing particulate emissions in turbocharged direct injection gasoline engines. The system optimizes the use of port fuel injection (PFI) in combination with direct injection (DI), particularly in cold start and other transient conditions. In the present invention, the use of these control systems together with other control systems for increasing the effectiveness of port fuel injector use and for reducing particulate emissions from turbocharged direct injection engines is described. Particular attention is given to reducing particulate emissions that occur during cold start and transient conditions since a substantial fraction of the particulate emissions during a drive cycle occur at these times. Further optimization of the fuel management system for these conditions is important for reducing drive cycle emissions.

    摘要： A number of systems and methods are disclosed which increase the replenishment interval for anti-knock fluid. This is especially important during activities which require a large amount of anti-knock fluid, such as towing. In some embodiments, the systems and methods are used to reduce anti-knock fluid consumption. For example, changes to engine operation, such as rich operation, spark retarding, upspeeding, and variable valve timing, all serve to reduce the amount of anti-knock fluid required to eliminate knocking. In other embodiments, the composition of the anti-knock fluid is modified, such as by using a higher octane fluid, or through the addition of water to the anti-knock fluid. In other embodiments, the replenishment interval is increased through a larger anti-knock fluid storage capacity. In one embodiment, a three tank system is used where the third tank can be used to store gasoline or anti-knock fluid, depending on the driving conditions.

    摘要翻译： 公开了许多系统和方法，其增加了防爆液体的补充间隔。 这在需要大量抗爆液体（如牵引）的活动中特别重要。 在一些实施方案中，系统和方法用于减少抗爆液体消耗。 例如，发动机操作的变化，例如丰富的操作，火花熄灭，升速和可变气门正时，都用于减少消除爆震所需的防爆液体的量。 在其它实施方案中，抗爆液体的组合物例如通过使用较高辛烷值的流体，或通过向防爆液体中加入水进行改性。 在其他实施例中，补充间隔通过较大的防爆液体储存容量增加。 在一个实施例中，使用三罐系统，其中根据驾驶条件，第三罐可以用于储存汽油或防爆液体。
