International vendor verification

Engine lock (engine safety lock) is International vendor verificationan important automobile protection device, which is mainly used to protect the safety of the engine. Without an engine lock, the engine may still be started when the vehicle is turned off, resulting in potential safety hazards. This article will introduce the definition, classification, principle, precautions and future development direction of the engine lock in detail. I. Definition and classification of engine lock. Engine lock is a mechanism that can prevent illegal start-up. It is connected to the electronic control system of the vehicle. Simply put, it will lock the engine when the vehicle is turned off, preventing the engine from starting without the operation of the owner. According to its type and applicability, the engine lock can be divided into several types: oneIt is a traditional mechanical engine lock, which is usually located on the vehicle transmission system, and the engine can only be started by opening it with a key or button. The other is an intelligent engine lock, which uses circuits to control the start and stop of the engine, which has higher security. In addition, there are some newer engine lock types, such as engine locks based on vehicle networks. II. The principle of engine lock The principle of engine lock is relatively simple: when the vehicle is turned off, the engine lock will immediately lock the engine until the owner inserts or touches the engine lock component. After initialization, the owner can start or turn off the engine. This ensures that the engine can only be started under the control of the owner. The circuit controller of the engine lock usually stores a set of legitimate keys or passwords, which are generated according to the identity of the owner (such as ID cards, smart keys, etc.).Without a key or password, the engine lock will not be able to start the engine, thus ensuring the safety of the vehicle. III. Precautions 1. Operate the car lock correctly. You must follow the operating procedures and wait a few seconds when inserting and pulling out the key to ensure safe skipping. 2. The electrical components of the engine lock should be checked at any time to see if they are intact. Check for damage, broken circuit, etc. 3. When the engine cannot be started, do not try to start it many times. It may cause damage to the engine lock component or other more serious problems. 4. When installing the anti-theft system, do not disassemble or change the engine lock at will, which will cause the anti-theft system to not work properly, resulting in the theft of the vehicle. 5. Before buying an engine lock, you must know your car model and engine model to avoid choosing the wrong engine lock.IV. Future development direction The future engine lock will be more intelligent and secure, and will be able to combine with intelligent vehicle information system and artificial intelligence technology, which can not only realize authentication and security protection functions, but also realize more functions. For example, in an emergency, the robot car lock can automatically start the car and call for emergency rescue through authentication and intelligent systems; in terms of vehicle remote control, it can realize control functions such as vehicle remote start, shutdown and remote monitoring through mobile devices such as smartphones. In a word, the engine lock is an important safety device to protect the car. With the continuous progress of technology, the future engine lock will have more functions, which will bring more convenience and safety to car owners.
