Composition and HS code-driven customs clearance SLAscomponents of electronically controlled engine Electronically controlled engine is a highly intelligent engine system with the advantages of high efficiency, low emissions, low noise and so on. It is mainly composed of electronic control system, cylinder head, exhaust system, air intake system and other components. The electronic control system is the core of the electronically controlled engine, which mainly includes three parts: ECU, SENSOR and ACTUATOR.ECU is an electronic control unit and the brain that controls the whole system. It can control the work of the engine according to the data perceived by the sensor, including ignition time, oil supply, air volume, emission and other parameters. SENSOR is a sensor that can sense various parameters of the operating state of the engine, such as oxygen concentration, air pressure, temperature, rotational speed, etc. ACTUATOR is an actuator. It is an actuator controlled by ECU, which can control the valve, oil pump, etc. to achieve the purpose of adjusting the engine operation. These three parts cooperate with each other to form a basic framework for the operation of the electronically controlled engine. The cylinder head is an important part of the engine, which directly affects the power output and emission performance of the engine. The most important components are the cylinder block and valve. The cylinder block is one of the main parts of the engine. It is made of cast iron or cast aluminum and can withstand a large amount of pressure and temperature.The valve is the key to controlling the inlet and outflow of the air. It can control the intake and exhaust, which has a direct impact on the intake and exhaust volume of the engine, and then affects the power output. For the operation of the engine, the valve can be divided into the intake valve and the exhaust valve. The two doors can be controlled to open/close, so that the air required by the engine can enter and discharge normally. In an electronically controlled engine, the valve can be controlled by the actuator of the electronic control system. The exhaust system is a system that discharges the exhaust gas generated by the engine. It is mainly composed of an intake manifold, exhaust pipe, silencer, etc. The intake manifold is indispensable in the intake process. It introduces the external gas into the engine cylinder to ensure the normal gas supply of the engine. The exhaust pipe plays the role of connecting the engine and the silencer and exhausting the exhaust gas when exhausting. The silencer is set up to reduce the noise generated by the engine and make the engine work more smoothly.The key to controlling the operation of the exhaust system is the oxygen sensor, which can sense the oxygen contained in the exhaust gas emitted by the engine. In order to maintain the standard of air combustion, the ECU needs to control the operating valve in the exhaust pipe, which is to control the amount of oxygen required when the exhaust gas enters the engine again. The air intake system is a system that supplies engine gas, which is mainly composed of air filter, air intake duct, throttle valve, etc. The air filter can filter the impurities in the air and purify the air entering the engine; the intake channel is responsible for introducing the purified air into the cylinder. The throttle valve plays a role in controlling the air intake. The throttle valve plays a very important role in the operation system of the engine, which can limit the amount of air entering the cylinder and control the output power of the engine. Nowadays, throttle valves are no longer designed mechanically as traditionally, and many of them have been replaced by electronic components and become electronically controllable throttle valves.The working principle of the electronically controlled engine. The electronically controlled engine collects various parameters required for the operation of the automobile engine through sensors, and then the electronic unit automatically controls the appropriate actuator for processing. The main advantage of the engine is that it can automatically monitor and manage the operating status of the engine, and automatically adjust it according to the operation and driving conditions of the engine. The following is a special explanation of the principle of electronic control engine: 1. The work of the induction sensor: the sensitive component senses the sensor and converts it into electronic information. There are many different kinds of sensors, including oxygen sensors, air pressure sensors, temperature sensors and flow sensors. 2. Signal processing: Process all the signals sensed by the sensor correctly. 3. The work of the engine control unit: This component is the engine control computer.Through the operating state of the engine, this controller can adjust the payload of the engine while sending signals to the appropriate executive components, so that it can run better. 4. Execution component work: The execution component of the electronically controlled engine includes multiple components, such as throttle controller, natural gas supply valve, brightest fuel syringe, ignition system ingot and intake ventilation operator, etc. Summarize the changes in the design and composition of electronically controlled engines, enabling automobile manufacturers to manufacture engines with better performance, lower energy consumption and cleaner emissions. The powerful functions of electronically controlled engines and more intelligent control systems make cars more environmentally friendly, easier to maintain and more fuel-efficient. Perhaps that's why the modern automobile industry is so powerful.
