    • A system and method for controlling an engine include determining a desired engine brake torque and modifying the desired engine brake torque based on current engine operating conditions to determine a requested engine brake torque prior to determination of control parameters, including at least one of an airflow and a fuel quantity, to effect the requested engine brake torque. Preferably, the desired engine brake torque is modified by combining the desired engine brake torque with an idle speed torque to generate a first intermediate torque, comparing the first intermediate torque to an actual engine brake torque to generate a second intermediate torque, generating a feedback correction torque based on the second intermediate torque, and combining the first intermediate torque, the feedback correction torque, and a third intermediate torque to determine the requested engine brake torque, where the third intermediate torque represents accessory load or a frictional torque loss which varies with temperature.

    • Secondary air is strategically introduced into a combustion chamber of an internal combustion engine event after the main combustion event to reduce HC and CO emissions. While the technique is applicable to virtually any otto cycle engine, it is particularly well-suited for use in a “rich burn” utility engine typically operating at an equivalence ratio (ER) of about 1.2 or above. Such engines start easily, run well, and emit low levels of NOx at ERs on the order of 1.2. The invention takes advantage of these benefits by admitting an air/fuel charge and allowing otto-cycle combustion to occur in at least generally the usual fashion (although at least preferably as rapidly as possible for a given engine design), using the standard fuel-rich carburetor calibration to fuel the engine. Then, a subsequent reaction process is initiated by supplying supplemental air to the engine in quantities and at times that assure reaction of the still-hot residual HC and CO products with oxygen in the supplemental air. The secondary reaction dramatically reduces HC and CO emissions while retaining NOx emissions at or near the low levels enjoyed by rich burn utility engines.
    • 在主燃烧事件之后,二次空气战略性地引入内燃机事故的燃烧室,以减少HC和CO排放。 虽然该技术适用于几乎任何的otto循环发动机,但是它特别适用于通常以约1.2或更高的当量比(ER)操作的“富燃烧”公用事业发动机。 这样的发动机容易启动,运行良好,并在约为1.2的ERs中排放低水平的NOx。 本发明通过承认空气/燃料装料并且允许至少通常以通常的方式(尽管至少优选地对于给定的发动机设计尽可能快地发生)来利用这些益处,使用标准燃料 - 丰富的化油器校准来燃烧发动机。 然后,随后的反应过程是通过向发动机提供补充空气来启动的,并且有时确保仍然残留的HC和CO产物与补充空气中的氧的反应。 二次反应极大地降低了HC和CO的排放,同时保持了富氧燃烧效用发动机所享有的低水平或接近低浓度的NOx排放。
