    • A variety of methods and arrangements for controlling the operation of an internal combustion engine in a skip fire variable displacement mode are described. Generally, an engine is controlled to operate in a skip fire variable displacement mode. In the variable displacement mode, selected combustion events are skipped so that other working cycles can operate at better thermodynamic efficiency. More specifically, selected “skipped” working cycles are not fired while other “active” working cycles are fired. Typically, fuel is not delivered to the working chambers during skipped working cycles. In one aspect of the invention, a firing pattern is determined that is not fixed but the active working cycles are selected to favor the firing of working chambers that have recently been fired at least in part to reduce wall wetting losses. In another aspect of the invention, when an active working cycle follows a skipped working cycle in the same working chamber, the quanta of fuel injected for delivery to the working chamber is increased relative to the quanta of fuel that would be delivered to the working chamber when the active working cycle follows another active working cycle in the same working chamber in order to compensate for wall wetting losses that occur during skipped working cycles.
    • 描述了用于在跳火可变位移模式中控制内燃机的操作的各种方法和装置。 通常,发动机被控制为以跳火可变排量模式操作。 在可变位移模式中,跳过所选择的燃烧事件,使得其他工作循环可以以更好的热力学效率运行。 更具体地,在其他“活动”工作循环被触发时,选定的“跳过”工作循环不被触发。 通常,在跳过的工作循环期间,燃料不会传送到工作室。 在本发明的一个方面,确定了不固定的点火模式,但选择了主动工作循环以有利于最近已经至少部分地被烧制的工作室的点火以减少壁湿润损失。 在本发明的另一方面,当主动工作循环跟随在相同工作室中跳过的工作循环时,喷射用于输送到工作室的燃料量相对于将被输送到工作室的燃料量增加 当主动工作循环在相同的工作室中跟随另一个主动工作循环,以补偿在跳过的工作循环期间发生的壁湿润损失。
