动力总成系统

德尔福探针式空气计量器采用热线风速仪测定发动机吸收的空气量。  The concept is simple, the implementation is unique.  The heart of the design is a platinum-based, glass-coated, heated sensing element which is a low mass, quick responding device used in a bridge circuit configuration.  这个部件是高导电性和低导热性的独特结合体，能将空气流动时的噪声比信号最大化。  德尔福探针式空气计量器的“大脑”（核心部分）是安装在一个定制集成电路里。

德尔福探针式空气计量器的输出信号由所需电力决定，用以保持热感应部件处于一个特定的高于室温的温度之上的环境中。  For gasoline engines, the control module utilizes the air meter output signal to precisely determine the scheduling of fuel, enabling an optimal air/fuel ratio and, thus, helping reduce emissions while maintaining drivability.  对于柴油发动机来说，控制器一般采用空气计量器来确定废气再循环的计划。

As more stringent emissions regulations are applied to diesel engines, accurate air flow becomes more and more important.  To help manufacturers meet the requirements, Delphi now offers the most accurate air meters in the industry.

Delphi offers a family of interchangeable Probe Air Meters.  They can be integrated directly into an air induction system, or into a variety of customer-determined tube diameters:

• 单一型探头是一种低成本空气计量器，用一个加热部件测定单向空气流。
• 双重型探头采用两个加热感应部件，可以最精确最灵活地测定单向空气流。  这种选件是在空气感应系统中处理多样进气的最耐用设计。
• 分路式探头补偿在4缸和5缸涡轮增压发动机上所遇到的振动。  It offers both the superior durability of Delphi's heated sensor technology and by-pass air flow capability suitable for applications requiring pulse flow compensation air flow measurement.
  

优点

• Platinum-coated ceramic heated sensing element design is smaller and less fragile than competitive products.
• Heated sensing elements are very robust to damage from dust impingement.
• Heated sensing elements offer proven durability with more than 125 million in the field over the past 14 years.
  
• Patented temperature compensation algorithm offers robustness to changes in ambient air temperature.
• Patented dimple design eliminates the need for a flow straightener in most applications.
• Probe design offers low restriction air measurement driving increased horsepower.
• Interchangeability is enabled by common mounting footprint.
  

典型应用

德尔福空气计量器，也叫做空气流动传感器或者空气流量传感器，作为汽车发动机管理系统的一个部件，而且能够针对汽油和柴油发动机的应用而定制。

性能优势

Delphi's total systems approach, and unparalleled experience and knowledge of the air/fuel subsystem, provide the advantage for producing effective, reliable air meters.  德尔福以空气计量表为基础的加燃料策略让产品更耐用更能迅速投入市场，替代了以增加密度为基础加燃料方法。  采用空气计量策略，改变动力总成零部件之后不再需要重新描绘容积效率表，因为空气流能够直接测定出来。

Delphi is the only supplier to offer air meters with dual heated sensing elements which enable any platform, regardless of air induction system variations, to incorporate an air meter into the air/fuel system with minimal engineering effort.

所有德尔福探头式空气计量器都以一个获得专利的微凹气流管理设计为特色，它可以更好地控制空气分离，使空气流穿过感应部件时能够更加一致，而且在管道特别应用上具有突出的性能。  三种设计都是通过相同的制造设备生产出来，这样减少了投资，并且最终减少了施加于客户的成本。  德尔福探针式空气计量器根据用户的选择来定制，包括：连接器的设计、镀金端子、供应电压、输出信号（频率或电压）等等。 

All Delphi Probe Air Meters can be upgraded to a ±1 percent accuracy specification level to help manufacturers of diesel engines meet the more stringent emissions requirements of the future, such as Euro 5.
