摘要： Methods and systems for controlling an internal combustion engine are provided. One example method may include closing an intake valve later during a cylinder cycle than a timing with which an amount of air inducted into a cylinder from an air intake passage would be maximized, and earlier during the cylinder cycle as a desired amount of air to be inducted into the cylinder increases, while an engine is operating at a given engine speed. The method may further include closing the intake valve earlier during a cylinder cycle as the engine speed increases when the desired amount of air to be inducted into the cylinder is at a maximum.
摘要翻译： 提供了用于控制内燃机的方法和系统。 一个示例性方法可以包括在气缸循环期间稍后关闭进气门比从空气进气通道引入气缸的空气量将最大化的时刻，以及在气缸循环期间较早的期望空气量 引擎进入汽缸增加，而发动机在给定的发动机转速下运行。 该方法还可以包括当汽缸循环期间较早地关闭进气门，因为当被引入气缸的所需量的空气处于最大值时，发动机转速增加。

摘要： A rocker cam (40) is comprised of a first split body (41) and a second split body (45), which are joined with a joint split face that contains an axial line of a cam shaft (3). The first split body (41) has a first pin support portion (42) that supports one end portion of the connection pin (31), and the second split body (45) has a second pin support portion (46) that is located so as to face the first pin support portion (42) and supports the other end portion of the connection pin (31). The connection pin (31) is supported at the first and second pin support portions (42,46) at its both end portions. Accordingly, a separation force that acts on the first and second split bodies of the rocker cam during its repeated rocking movement can be reduced without improperly increasing its rigidity.

摘要： A valve driving device comprising: a tappet assembly 3 adapted to slide in a tappet guide hole 4 to drive a valve 5 and including a high-speed center tappet 31 and low-speed side tappet 32; and a high-speed center cam 21 and a low-speed side cam 22 (23) provided corresponding to the center tappet 31 and the side tappet 32. A depression 21 a is formed which is depressed from a base circle to roughly the same profile as a shaft section of the camshaft 2 so that the cam portion over a predetermined angle range where a cam nose section is not formed in the centrally located center cam 21 is smaller than the base circles of the outside located side cams 22 (23) in profile.
