  不同类型的传感器在汽车上有着不同的作用,汽车传感器有很多种类,今天和大家一起来了解下常见的汽车传感器都有哪些类型以及这些传感器的作用是什么。

  Different types of sensors have different functions in automobiles. There are many kinds of automobile sensors. Today, let's learn what types of common automobile sensors are and what the functions of these sensors are.

  压力传感器

  Pressure sensor

  压力传感器主要是用来感知进气流量所形成的真空压力,并转换成电信号输送给微机控制器,紧控制器计算处理后,发出喷油量与喷油时刻的信号。

  The pressure sensor is mainly used to sense the vacuum pressure formed by the intake flow rate, and convert it into electrical signal and send it to the microcomputer controller. After the controller calculates and processes it, it sends out the signal of fuel injection quantity and fuel injection time.

  车速传感器

  Speed sensor

  车速传感器用于测量发动机的行驶速度,并且将该信号输送到ECU,用来控制发动机怠速和汽车加减速时的空燃比。

  The vehicle speed sensor is used to measure the driving speed of the engine and send the signal to ECU to control the air-fuel ratio of engine idling and vehicle acceleration and deceleration.

  空气流量传感器

  Air flow sensor

空气流量传感器

  空气流量传感器用于测量发动机吸入的空气量,换成电信号提供给ECU作为喷油时间的基准信号。

  The air flow sensor is used to measure the amount of air inhaled by the engine, which is replaced by electrical signal and provided to ECU as the reference signal of fuel injection time.

  ABS传感器

  ABS sensor

  ABS传感器用来监控车速,在急刹时,将车轮的转速反馈给刹车系统,由刹车系统来控制车轮有克制的转动,以达最佳刹车效果;

  The ABS sensor is used to monitor the vehicle speed. In case of emergency braking, the speed of the wheel is fed back to the braking system. The braking system controls the wheel rotation to achieve the best braking effect;

  节气门位置传感器

  Solar term door position sensor

节气门位置传感器

  节气门位置传感器用于检测节气门的开度,通过杠杆机构与节气门联动,测量节气门打开的角度电压信号,并将信号传输给ECU作为喷油量和点火提前角修正的基准信号。

  The throttle position sensor is used to detect the opening of the throttle valve. It measures the angle voltage signal of the throttle opening through the linkage of the lever mechanism and the throttle valve, and transmits the signal to the ECU as the reference signal of fuel injection quantity and ignition advance angle correction.

  曲轴位置传感器

  Crankshaft position sensor

  曲轴位置传感器用于检测上止点信号、曲轴转角信号和发动机转速信号,提供给ECU作为确定点火正时、喷油正时及工作顺序的基准信号。

  The crankshaft position sensor is used to detect the top dead center signal, crankshaft angle signal and engine speed signal, and provides the ECU as the reference signal to determine the ignition timing, fuel injection timing and working sequence.

  凸轮轴位置传感器

  Camshaft position sensor

  凸轮轴位置传感器拥有检测凸轮轴位置和转角,提供ECU曲轴转角基准位置信号,作为喷油正时控制和点火正时控制的主控制信号。

  The camshaft position sensor can detect camshaft position and angle, and provide ECU crankshaft angle reference position signal as the main control signal of fuel injection timing control and ignition timing control.

  水温传感器

  Water temperature sensor

  水温传感器用于感知发动机冷却水的温度,即冷启动和暖车信号,此时微机控制器输出增加喷油量的控制信号,使混合气加浓便于发动机的冷启动与迅速暖车。

  The water temperature sensor is used to sense the temperature of engine cooling water, i.e. cold start and warm-up signals. At this time, the microcomputer controller outputs the control signal to increase the fuel injection quantity, so as to enrich the mixture and facilitate the cold start and rapid warm-up of the engine.
