Where to Find the Engine Code?
2 Answers
You can locate the engine code in the following places: vehicle license, motor vehicle registration certificate, car purchase invoice, factory certificate of compliance, operating license for commercial vehicles, vehicle purchase tax payment certificate, public security authority registration records, vehicle insurance card, and on the engine nameplate. The engine model is designated by the manufacturer in accordance with relevant regulations or industry practices to indicate engine-related information. This includes the engine's manufacturer, specifications, performance, features, technology, purpose, and production batch. Engines installed in passenger cars or multi-purpose passenger vehicles are required to display the professional manufacturer's name, model, and production number as stipulated. Components of the engine number: Prefix: Represents the product series symbol and generation indicator, with letters chosen by the manufacturer as needed, subject to approval by relevant authorities. Middle section: Consists of symbols indicating the number of cylinders, stroke type, cylinder arrangement, and cylinder diameter. Suffix: Denotes structural and usage characteristics, represented by letters. Ending: Differentiation symbol. When distinctions are needed within the same series due to improvements or other reasons, the manufacturer selects appropriate symbols for identification.
I've checked the engine code several times, exploring it right on my own car. The engine code is usually engraved on the engine block, often in a prominent position at the front or side, such as near the intake or water pump. You'll need to open the hood first, and it's safer to do this when the engine is cold to avoid burning your hands. If the metal surface is dirty, gently wipe it with a cloth and use a flashlight to carefully read those numbers and letters. Besides the engine itself, sometimes there's related information on the VIN plate at the lower left corner of the windshield, or you can check the vehicle information page in the owner's manual. This code is quite important, whether it's for confirming engine details when buying a used car or handling transfer procedures. If you can't find it, don't worry—just ask a mechanic friend to take a quick look, or try figuring it out yourself, which can be quite interesting.
