2.6 汽油喷射发动机空燃比的调控方式汽油喷射与化油器的根本区别,除了形成混合气的方式不同外,还在于它们调控空燃比的方式不同。汽油喷射发动机空燃比的调控方式是指吸入空气量的检测方式和燃油喷射方式。2.6.1 空气量的检测方式空气量的检测方式(图2—12),可以分为直接检测和间接检测两种。直接检测方式也称质量流量方式,简称流量型。它利用配装在进气管处的空气流量计直接测量吸入发动机气
2.6 Gasoline injection engine air-fuel ratio control method The basic difference between gasoline injection and carburetor, in addition to the formation of a mixture of different ways, but also that they regulate the air-fuel ratio in different ways. Gas injection engine air-fuel ratio control mode refers to the amount of intake air detection and fuel injection. 2.6.1 Air volume detection method Air volume detection mode (Figure 2-12) can be divided into direct detection and indirect detection of two. Direct detection method is also called mass flow method, referred to as flow type. It uses the air flow meter installed in the intake pipe to directly measure the intake of engine air
