How to Check the Last Six Digits of a Car's Engine Number?

[Sylvia]

The last six digits of a car's engine number can be directly viewed on the vehicle's registration certificate, purchase invoice, motor vehicle registration certificate, factory certificate, or vehicle purchase tax payment receipt. The first part of the engine number: Includes the product series code, generation symbol, and regional or enterprise code, which are selected by the manufacturer as needed using corresponding letters, but must be approved and filed by the industry standard standardization unit. The middle part of the engine number: Consists of the cylinder count symbol, cylinder arrangement symbol, stroke symbol, and cylinder diameter symbol. The last part of the engine number: Distinguishing symbol. When differentiation is needed for the same product series due to improvements or other reasons, the manufacturer selects an appropriate symbol, which can be separated from the preceding part by a "-".
