进气/油集成装置

进气/油集成装置是一种高度集成化的发动机核心子系统。它将原本分散的进气部件（如进气管、节气门体、进气歧管）和燃油部件（如燃油轨、喷油器）等整合在一个紧凑的模块中。

进气/油集成装置其主要目的是通过优化结构布局，实现发动机性能的提升。它能够：

· 进气/油集成装置提升发动机响应与动力输出：通过优化进气气流和燃油雾化效果，使空气与燃油在进入燃烧室前实现迅捷混合，从而提升燃烧效率，使发动机获得更强劲的动力。

· 进气/油集成装置减少污染排放：更充分的燃烧有助于降低尾气中有害物质的排放。

· 进气/油集成装置优化空间布局与降低成本：集成化设计减少了复杂的独立管路连接，使发动机结构更紧凑，空间利用率更高，同时也降低了制造成本。以美国Delphi公司的概念样机为例，该产品通过彻底整合进气系统和燃料系统的外围零部件，展示了降低成本和提高性能的可能性。

进气/油集成装置主要设计与特点

· 模块化集成设计：

  · 将油轨水平安装在集成腔室外侧，喷油器输出端则与腔室接通，输入端与油轨固定接通。

  · 采用集成底板或类似结构，将多个增压器的进回油管路进行简化布置。

· 迅捷油气混合：配合燃油轨高压多点雾状喷射燃油，喷油器将来自油轨的汽油雾化喷入腔室与空气混合，使空气和燃油在进入燃烧室前在缸体内迅捷混合。

· 精准进气控制：集成腔室的进气端通常安装有由电机总成控制的可旋转阀片（如节气门），用以控制进入各气缸的进气量。

· 紧凑结构与轻量化：此类集成装置结构紧凑，常采用铝合金等轻质材料制作，有助于减轻整体重量。

Product Overview of Intake  Fuel Integration Device

The Intake  Fuel Integration Device is a highly integrated core subsystem of an engine. It consolidates originally dispersed intake components (such as intake pipes, throttle bodies,  intake manifolds)  fuel components (such as fuel rails  injectors) into a compact module.

Its primary purpose is to enhance engine performance through optimized structural layout. It achieves this by:

· Improving Engine Response  Power Output: By optimizing intake airflow  fuel atomization, it enables air  fuel to mix efficiently before entering the combustion chamber. This improves combustion efficiency, allowing the engine to deliver more powerful performance.

· Reducing Pollutant Emissions: More complete combustion helps lower the emission of harmful substances in the exhaust gases.

· Optimizing Space Layout  Reducing Costs: The integrated design reduces complex independent piping connections, resulting in a more compact engine structure, higher space utilization,  lower manufacturing costs. Taking the concept prototype  Delphi USA as an example, this product demonstrated the potential for cost reduction  performance improvement by thoroughly integrating peripheral components of the intake system  fuel system.

Design  Features

· Modular Integrated Design:

  · The fuel rail is mounted horizontally on the outside of the integrated chamber, with the fuel injector's output end connected to the chamber  its input end fixed to the fuel rail.

  · An integrated baseplate  similar structure is used to simplify the layout of oil inlet  return lines for multiple turbochargers.

· Efficient Air-Fuel Mixing: Working in conjunction with the fuel rail's high-pressure, multi-point mist-like fuel injection, the injectors spray atomized fuel into the chamber to mix with air, ensuring efficient mixing of air  fuel before they enter the combustion chamber.

· Precise Air Intake Control: The intake end of the integrated chamber typically houses a rotatable valve plate (e.g., a throttle valve) controlled by an electric motor assembly, which precisely regulates the intake air volume entering each cylinder.

· Compact Structure  Lightweight: Such integrated devices are compact in structure  often manufactured using lightweight materials like aluminum alloy to help reduce overall weight.
