Research on Some Key Techniques of Manifold Absolute Pressure(MAP) Sensor in Vehicle Motor 汽车发动机进气歧管压力传感器关键技术的研究
Manifold absolute pressure ( map ) sensor test 歧管绝对压力(MAP)(MAP)感知器测试
When cranking speed increased, the drop rate of intake manifold absolute pressure ( MAP ) is enhanced, resulting in poor control of in-cylinder mixture, therefore, the combustion and emission deteriorate significantly. 结果发现提高拖动转速造成起动过程进气压力变化率升高,使得精确控制缸内混合气浓度更加困难,导致燃烧和排放恶化。
