How to Check a Car's Engine Number?
1 Answers
The engine number is generally located on the outer surface of the engine cylinder block, or on the vehicle's nameplate or the nameplate inside the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle. It contains crucial information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or company conventions, and the attributes of the engine. It is used to indicate information such as the manufacturer, specifications, performance, features, production process, purpose, and batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the professional manufacturer's name, model, and production number. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, and each engine has a unique number. Composition of a car's engine number: Prefix: Includes the product series code, generation symbol, and regional or company code. Manufacturers may choose appropriate letters as needed, but these must be approved and recorded by the industry standardization unit. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Rear section: Comprises symbols for structural features and usage characteristics. Suffix: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers may select appropriate symbols. The rear section and suffix can be separated by a hyphen (-).
