The Hearthstone arenacomposition of the electronic control engine In modern cars, the electronic control engine is an important part of prosperity. According to the needs of the driver and different speeds, it realizes accurate control of combustion through various control units and sensors. The timing of oil injection and ignition ensures that the engine is always in the best working condition. At the same time, under the premise of ensuring power and fuel efficiency, it achieves the lowest emission and ensures the reliability, durability and safety of the vehicle. This article will introduce the composition and principle of the electronically controlled engine in detail. The basic composition of the engine control system The control system of the electronically controlled engine is mainly composed of the following parts: 1. Sensors: such as oxygen sensor, air flow sensor, water temperature sensor and crankshaft position sensorEtc., the sensor collects various parameters during the engine operation, converts them into electrical signals, and sends them to the control unit for processing. Two. Control unit: also known as ECU. The control unit is responsible for receiving the electrical signals generated by the sensor, and calculates the timing and various parameters of ignition, fuel injection, acceleration and valve according to these signals, and then outputs to the actuator for control. 3. Actuator: The actuator is the actuator of the signal output by the control unit, such as the ignitioner, oil pump, fuel injector, intake valve actuator and other equipment of the engine. Four. System display and fault indication: ECU also has a functional system fault check, which provides a basis for electronic detection and fault analysis through the setting and storage of engine fault codes. The above parts are combined to form a hair.The motivation control system enables it to work under safe, efficient and environmentally friendly conditions according to the needs of the driver and the environment. The working principle of the electronically controlled engine The electronically controlled engine realizes the intelligent control of the engine through the collaboration between the sensor and the control unit and the actuator. When the driver turns on the ignition switch of the car, the control unit of the car starts to work. If there is no resistance, the control unit will immediately start the motor and ignite the fuel through the ignition system to start running the engine. ECU constantly receives data from the sensors of the car, including air flow, throttle opening, engine speed and car speed, etc., and then calculates how to change the working conditions of the car to obtain the best fuel efficiency and power performance. During the calculation process, the control unit also needs to select the appropriate fuel intake and ignition timing according to different driving modes to improve the driving experience.For example, when the car needs to accelerate rapidly, the control unit will output more opening signals to the throttle of the car to improve the fuel intake and torque output of the engine, so as to achieve faster acceleration and rapid overtaking. At the same time, ECU also needs to diagnose the working condition of the car and show the fault code to the owner. If a failure occurs, it will enter the recovery mode. For example, when the engine speed is abnormal, the ECU control unit will reduce the speed of the car to prevent damage or more serious failures. In a word, the working principle of the electronically controlled engine is to adjust fuel consumption and achieve the best performance through the collaboration of control units, sensors and actuators. At the same time, in order to avoid excessive damage, the engine will be automatically adjusted. If there is a problem, the control unit will also self-diagnose. Summarize in Hyundai MotorIn the middle, the electronically controlled engine has become the basic technology of the prosperous automobile industry. It intelligently controls the engine through various control units and sensors, so that the car is always in the best condition, while meeting the requirements of high efficiency, safety, durability and environmental protection. In the future, people will rely more on electronic control systems to develop better engines and more intelligent cars, which requires continuous innovation and research and development of science and technology and researchers.
