L系统的核心元件电控单元,简称ECU,它的作用是接受转速、水温、空气流量等信号,经过处理后控制喷油嘴等元件,使发动机正常运转。ECU为高度集成化的电子元件,一般无法修复,一旦损坏,只能整体更换。 L系统区别于其它喷油系统的最大特点是采用了精确的空气流量计。 机械式的折翼门空气流量计输出信号是可调的,而热线、热膜式流量计一般无法调整,但它们由于没有机械磨损,工作起来很可靠。无论是ECU还是空气流量计,都
L system’s core components Electronic control unit, referred to as ECU, its role is to accept the speed, water temperature, air flow and other signals, after treatment control injector and other components, so that the normal operation of the engine. ECU is highly integrated electronic components, generally can not be repaired, once damaged, only the overall replacement. The most distinguishing feature of the L system from other fuel injection systems is the use of an accurate air flow meter. Mechanical flap door air flow meter output signal is adjustable, and hot wire, hot film flow meter generally can not be adjusted, but because they have no mechanical wear and tear, work reliably. Either ECU or air flow meter, all
