摘要： An intake manifold includes an upper shell, a lower shell, and a middle shell that interconnects the upper and lower shells. The lower shell has a plurality of longitudinally spaced shell ports. Each shell port is adapted for installation over a corresponding intake port for an engine cylinder head. The upper shell has a plurality of runners that are used to guide air to the shell ports. The middle shell has a plurality of channels that interconnect the runners and the shell ports such that air can flow through the runner to the cylinder intake port. Fuel injector pockets are formed within the upper, middle, and lower shells with each of the pockets having an injector opening in communication with the corresponding shell port. An internal fuel rail, formed between the upper and middle shells, supplies fuel to each of the injector pockets. A fuel injector is installed into each injector pocket such that the injectors are substantially enclosed within the manifold. An internal wire harness rail, formed between the upper and middle shells, supports a wire harness that electrically connects each of the injectors to a power supply.

摘要翻译： 进气歧管包括上壳体，下壳体和互连上壳体和下壳体的中间壳体。 下壳体具有多个纵向间隔的壳体端口。 每个外壳端口适于安装在用于发动机气缸盖的相应进气口上。 上壳体具有用于将空气引导到壳体端口的多个流道。 中间壳体具有多个通道，其将流道和壳体端口互连，使得空气可以流过流道到气缸进气口。 燃料喷射器凹穴形成在上壳体，中部和下部壳体内，每个凹穴具有与相应的壳体端口连通的喷射器开口。 形成在上壳体和中壳体之间的内部燃料轨道向每个喷射器腔室供应燃料。 燃料喷射器安装到每个喷射器腔中，使得喷射器基本上封闭在歧管内。 形成在上壳体和中壳体之间的内部线束导轨支撑将每个喷射器电连接到电源的线束。
