进气歧管漏气作为汽油机的一种故障,对不同的电控燃油喷射系统发动机的怠速有不同的故障表现。按BOSCH公司的空气计量检测方式分类,现常见的电控发动机可分为两类:一类为进气歧管压力计量式,将进气歧管绝对压力和发动机转速信号作为基本信号计算充气量;另一类为质量流量式,利用热线或热膜式空气流量传感器直接计算气缸的进气量。进气歧管漏气 Intake manifold leakage as a failure of the gasoline engine, different electronic control fuel injection system engine idle speed has different fault performance. By BOSCH’s air measurement test methods, the current common control of electric engine can be divided into two categories: one for the intake manifold pressure gauge, the absolute intake manifold pressure and engine speed signal as the basic signal to calculate the amount of inflation ; The other is mass flow type, the use of hotline or hot film air flow sensor directly calculate the cylinder intake.
