摘要： Systems and methods are provided for an exhaust gas recirculation (EGR) system in a vehicle. In one example, a system may include a cylinder head including an integrated exhaust manifold (IEM), an EGR cartridge including an EGR valve positioned in the cylinder head at a central collector region of the IEM, and a water jacket formed within the cylinder head, the water jacket including at least one cooling passage that extends around a circumference of the EGR cartridge. In this way, an EGR system is provided that has a reduced volume between an exhaust valve of a cylinder to the EGR valve, reducing packaging space and complexity of the EGR system while increasing engine performance.

摘要： A cam cover cap plug for use with a cylinder head assembly to fill the opening that remains when an accessory unit such as a READ utility pump is not utilized. The cam cover cap plug is preferably a one-piece, molded component formed from a plastic or a metal. The cam cover cap plug includes a back, a front, an upper surface and a lower surface. The upper surface is arched and defines a half-round configuration. The lower surface is flat and includes integrated cylinder head fasteners extending from the flat surface. The arched, half-round configuration of the upper surface provides a full and complete sealing area with the half-round opening of the cam cover formed to receive the accessory unit. The fasteners of the lower surface are preferably integrated dowels. The integrated dowels locate the cam cover cap plug base to the cylinder head of the cylinder head assembly.

摘要： An engine is provided with a block forming a cylinder, a head, and a gasket positioned between the block and the head. The gasket has first and second outer layers and a distance layer positioned therebetween. The first layer defines a first aperture and a bead surrounding the cylinder. The distance layer defines a second aperture concentrically arranged between the first aperture and the bead. The gasket has a stopper layer extending inwardly from the distance layer to a circular stopper element positioned adjacent to and aligned with the first aperture. A method of sealing an engine includes compressing a gasket between a block and a head to form a primary seal at a first interface and a secondary seal at a second interface between first and second outer layers and an intermediate layer, the first interface being positioned between the second interface and a bead surrounding a cylinder.

摘要： A gasket for use with in an internal combustion engine having lubricating oil drainback passageways and an integrated exhaust manifold formed in the cylinder head is disclosed. The gasket includes at least one drainback passageway opening to fit substantially around the drainback passageways formed in the cylinder block. A loose component-capturing constraint feature is integrally formed with the gasket and effectively provides a bridge over the drainback passageway opening of the gasket. The constraint feature does not restrict the flow of lubricating oil and may be of any of several designs including, for example, a rib. The cylinder head gasket is preferably of a multi-layer construction and is preferably steel. The constraint feature may be a single gasket layer. The cylinder head gasket includes both active and non-active areas. The constraint feature may be either or both an active and a non-active area of the gasket.
摘要翻译： 公开了一种在具有润滑油回流通道的内燃机中使用的垫圈和形成在气缸盖中的集成排气歧管。 垫圈包括至少一个排水回流通道开口，基本上围绕形成在气缸体中的回流通道。 松散的部件捕获约束特征与垫圈一体地形成，并且有效地在垫圈的排水回路通道开口上提供桥。 约束特征不限制润滑油的流动，并且可以是几种设计中的任何一种，包括例如肋。 气缸盖垫片优选为多层结构，并且优选为钢。 约束特征可以是单个垫片层。 气缸盖垫片包括主动区域和非活动区域。 约束特征可以是垫圈的有效区域和非有效区域中的一个或两者。

摘要： An apparatus is provided having two mating components. The mating components include an engine and an engine front cover. A fastening boss is formed on at least one of the two mating components and configured to receive a threaded fastener to join the two mating components. A compression boss extends from a first of the two mating components to contact a second of the two mating components. The compression boss is dimensioned relative to the fastening boss to create compressive loading in the compression boss when the threaded fastener is tightened to join the mating components.

摘要： A fastener includes a shank having a threaded section with a first diameter and an unthreaded section with a second, smaller diameter. A flange is attached to the unthreaded section of the shank. A bushing has a tip, a base, and a tapered sidewall extending from the base to the tip. The bushing defines a central hole received on the unthreaded section with the base adjacent to the flange.

摘要： An internal combustion engine has a cylinder head defining an exhaust valve guide bore with a side wall and an end wall, and an exhaust valve stem passage extending between an exhaust port and the end wall of the bore. A diameter of the passage is less than a diameter of the bore. An exhaust gas valve guide is positioned in the bore and spaced apart from the end wall to form an air gap therebetween.
