Abstract: An exhaust gas recirculation device of an engine is provided to effectively cool EGR gas recycling from an air discharge machine to an air suction machine by using cold water of a water jacket. An EGR device includes a suction port(21), an EGR passage, an EGR valve(60), and a controller(50). The suction port is provided at a cylinder head(20) so that air is sucked into an air combustion chamber(30). The suction port is provided at one side thereof with an air introducing hole(24). The ERG passage includes a block EGR passage(71) for taking EGR gas discharged from an air discharge machine and a head EGR passage(72) to guide EGR gas into the air introducing hole of the suction port. The EGR valve is provided on the EGR passage to open/close the EGR passage. The controller operates the EGR value so that the EGR passage is open/closed based on a signal of a hydraulic air sensor. The block EGR passage passes through a water jacket of a cylinder block(10). The head EGR passage is formed in the water jacket of a cylinder head(20).
Abstract translation: 提供了一种发动机的排气再循环装置，通过使用水套的冷水，有效地将从气体排出装置将EGR气体循环再利用到吸气机。 EGR装置包括吸入口（21），EGR通道，EGR阀（60）和控制器（50）。 吸入口设置在气缸盖（20）处，使得空气被吸入空气燃烧室（30）。 吸入口的一侧设置有空气导入孔（24）。 ERG通道包括用于从排气机排出的EGR气体和头部EGR通道（72）的EGR排气通道（71），用于将EGR气体引导到吸入口的空气引入孔。 EGR阀设置在EGR通道上以打开/关闭EGR通道。 控制器操作EGR值，使得EGR通道基于液压空气传感器的信号而打开/关闭。 块式EGR通路通过气缸体（10）的水套。 头部EGR通道形成在气缸盖（20）的水套中。

Abstract: A variable valve operating system is provided to improve functions of a variable valve by constructing a valve device to have a mechanical structure instead of a hydraulic structure. A variable valve operating system comprises a cam follower(50) and a valve device. The cam follower includes an inner body(65) and an outer body. A locking member(60) is formed at one end of the inner body. The outer body surrounds a lateral portion of the inner body and is latched with the inner body by a latching device(70). If the inner body is latched with the outer body by the latching device, the inner and outer bodies perform the see-saw movement about a driving cam, thereby lifting an intake/exhaust valve(95) connected to the driving cam by a lost motion pin(90).

Abstract: A continuously variable valve lift system in an engine is provided to reduce a volume of the engine by adjusting the entire height of a cylinder head at a lower level. A continuously variable valve lift system in an engine includes a cam shaft(12), a rotary adjustment mechanism(14), a bearing member(18), a resilient member(20), and a rocker arm(22). The cam shaft is installed at a cylinder head to be linked to a crankshaft, and has a plurality of cams for opening/closing suction/discharge valves. The rotary adjustment mechanism has a first contact part variably adjusted according to an operation state of the engine and having a predetermined radius of curvature. The bearing member is pressed by the cam and the first contact part of the rotary adjustment mechanism to vary a moving trajectory in a dependent manner. The resilient member resiliently adheres the bearing member, the cam, and the rotary adjustment mechanism to each other. The rocker arm is installed to press the suction/discharge valves.
