介绍了发动机进气歧管压力传感器的标定系统和传感器静、动态标定方法。
This paper introduces the calibration system and static and dynamic calibration method of an engine intake manifold pressure sensor.
随着拖动转速升高，进气歧管压力降低，对应的喷油策略也应随之调整；
The intake manifold pressure is lower when the cranking speed increases, thus the fuel metering strategy should be modified.
如果发动机回火，进气歧管骤增的压力就迫使阀门向后移动。
If the engine backfires, the sudden pressure in the intake manifold forces the valve back.
由于重新设计的阀门，发动机不敏感，空气压力，将很容易运行只需吹的进气歧管。
With the redesigned valves, the engine is not sensitive to air pressure and will easily run just by blowing into the intake manifold.
歧管可以只是机械零部件或是完整的组件，包括止回阀，压力开关，伺服阀，电磁阀或过滤器。
Manifolds can be either machined components only or complete assemblies including check valves, pressure switches, servovalves, solenoids or filters.
在上面所给出P 0442示例中，燃油箱液面位置，进气空气温度和歧管绝对压力传感器将被应用。
In the P0442 example above, the fuel level, intake air temperature and manifold absolute pressure sensors are used.
本文研究的主要内容如下：首先，在自行设计的歧管绝对压力(map)传感器标定实验台上，对传感器进行了静、动态标定。
This dissertation mainly about: Firstly, the static and dynamic calibration experiment of MAP sensor was completed on a calibration experiment stage which was designed by us.
