Where to Find the Chassis Number and Engine Number?
1 Answers
The engine number is generally located on the outer surface of the engine 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, like a person's ID number, represents each vehicle and contains very important information about the car. The chassis number is stamped on the vehicle's frame. The specific location varies by manufacturer, so you can refer to your vehicle's manual. The engine model number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry practices, and the engine's attributes. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static brake power. Engines installed in passenger cars or multi-purpose vehicles are marked with the professional manufacturer's name, model, and production number as required. The chassis number, commonly referred to as the Vehicle Identification Number (VIN), is a unique code assigned by the manufacturer to identify a vehicle. The VIN consists of 17 alphanumeric characters, also known as the 17-digit identification code, chassis number, or 17-digit number. The combination of these characters ensures that no two vehicles of the same model will have the same number within 30 years, making it a unique identifier for the vehicle—often called the 'car's ID card.' It is typically found in the following locations: on the vehicle registration certificate and on the lower left side of the front windshield. It's important to note that the engine number is not the same as the engine model number. 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 number. The engine number, however, is the production serial number of the engine, and each engine has a unique number. Engine Number Composition: First Part: Includes the product series code, generation symbol, and regional or manufacturer code. Manufacturers may choose appropriate letters, but these must be approved and recorded by the industry standard authority. Middle Part: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear Part: Composed of symbols for structural features and usage characteristics. Tail Part: A distinguishing symbol. Manufacturers may use appropriate symbols to differentiate between improved versions or other variations within the same series. The rear and tail parts may be separated by a hyphen. The chassis number consists of 17 characters divided into three parts. Part 1: WMI—World Manufacturer Identifier (positions 1–3); Part 2: VDS—Vehicle Descriptor Section (positions 4–9); Part 3: VIS—Vehicle Identifier Section (positions 10–17).
