China HS code interpretation guide

Engine Control Module (ECM),China HS code interpretation guide also known as engine controller, is the most important component of the automobile engine management system.The engine computer controls the operating state of the entire car engine, including fuel supply and physicochemical state, ignition timing and angle, emission control, lubrication and cooling system, etc. The function of the engine computer The control of the car engine by the engine computer is comprehensive. The specific functions are as follows: 1. Monitoring: The engine computer can monitor various states of the engine through various sensors, such as air flow, oil pressure, temperature, oxygen concentration, etc. Two. Analysis: After the engine computer collects various data, it will analyze the data to calculate the optimal fuel supply and ignition timing and other parameters to achieve the best combustion efficiency. 3. Control: The engine computer controls the engine according to the results of data analysis to ensure the operating efficiency and emission compliance of the car by changing the amount of fuel, ignition time and angle, etc.Four. Fault diagnosis: The engine computer also has a fault diagnosis function. Once the engine fails, the engine computer will prompt the after-sales maintenance personnel to repair and maintain through the fault code. Advantages of engine computers The emergence of engine computers has greatly improved the performance and fuel economy of automobiles. The main reasons are as follows: 1. The engine computer can adjust parameters such as fuel supply and ignition timing in real time according to the engine status, so as to optimize the operation of the automobile engine and greatly reduce fuel consumption. Two. The engine computer will collect and store various engine data. At the same time, it can detect and deal with engine problems in time through the fault diagnosis function, and the maintenance can be more timely and efficient. 3. The engine computer can also greatly reduce the exhaust emissions of cars through emission adjustment.Challenges and problems Although the engine computer has so many advantages, it also faces some challenges and problems: 1. Complication of faults: With the continuous intelligence and electronicization of automobiles, the engine computer system has become more complex, and it is more likely to have problems during repair and debugging. Two. Safety issues and reliability: Engine computers are an important part of automobile safety. Its safety and reliability are related to the safety of the automobile during driving. More resources need to be invested to establish an audit mechanism to ensure its stability. 3. Difficulties in private maintenance: Engine computers have been widely used in the automotive industry, but due to the warranty policy, automobile manufacturers do not allow consumers to repair parts involving engine computers by themselves, which also increases the difficulty of maintenance of engine computers. Conclusion The emergence of engine computers canAs one of the important milestones in the process of automotive electronicization, its continuous improvement of intelligence will certainly inject new impetus into the automobile industry, improve people's expectations for automobile performance and safety, and continuously promote the development of the industry. Although there are various problems in the process of using the engine computer, these problems also prompt the engine computer to be constantly updated and upgraded. We believe that with the progress of technology, engine computers will be continuously improved in the future to provide us with more intelligent, safer and more powerful cars.
