一、电喷发动机中的燃油供应 电喷控制技术中,很重要的方面是依据发动机的进气量来控制喷油量,而对喷油量的控制又是通过调节喷油时间来实现的,这要求油路处于恒压状态。只有油路压力恒定,才能保证喷油时间与喷油量之间关系的唯一性,所以供油系统的压力恒定,成为能否精确控制喷油量的一个重要基础。现代电喷发动机的供油方式如图1所示。
First, the EFI engine fuel supply EFI control technology, a very important aspect is based on the amount of engine intake to control the amount of fuel injection, and the amount of fuel injection control is achieved by adjusting the injection time, This requires that the oil line be at a constant pressure. Only constant pressure of the oil line can guarantee the uniqueness of the relationship between injection time and fuel injection amount. Therefore, the constant pressure of the oil supply system becomes an important basis for accurately controlling the fuel injection amount. Modern EFI engine oil supply shown in Figure 1.
