How do you know that the pump pressure sensor is broken?


Common Rail EFI technology refers to an oil supply method in which the injection pressure generation and the injection process are completely separated from each other in a closed loop system composed of a high pressure oil pump, a pressure sensor and an electronic control unit (ECU). It is a high-pressure oil pump that delivers highpressure fuel to a common fuel supply pipe (Rail), which is precisely controlled by the oil pressure in the common fuel supply pipe, so that the pressure of the highpressure fuel pipe is independent of the engine speed, and the diesel engine can be greatly reduced. The degree to which the oil supply pressure varies with the engine speed. The sensor (English name: transducer/sensor) is a detection device that can sense the measured information and can transform the sensed information into an electrical signal or other required form of information output to meet the information. Requirements for transmission, processing, storage, display, recording and control.




The characteristics of the sensor include: miniaturization, digitization, intelligence, multi-function, systemization, and networking. It is the first step in achieving automatic detection and automatic control. The existence and development of the sensor allows the object to have senses such as touch, taste and smell, and let the object slowly become alive. Generally, it is divided into ten categories according to its basic sensing function: thermal element, photosensitive element, gas sensor, force sensor, magnetosensitive sensor, humidity sensor, sound sensor, radiation sensor, color sensor and taste sensor. .
