You just need to take all the documents provided by the 4S dealership to the DMV to get your license plate. Rubbing refers to the process of copying the stamped numbers on the car's engine and chassis frame. Definition: The engine and chassis frame of a car have numbers stamped with steel seals, similar to the serial number on a bicycle. These numbers are registered at the time of manufacture, mainly to facilitate tracking in case of theft and to prevent unauthorized modifications to the engine or body. During vehicle inspections, the vehicle management department (Vehicle Division) requires the numbers to be rubbed onto paper with a pencil for record-keeping. Rubbing depends on: Rubbing depends on the cylinder bore and piston stroke. Engine displacement is a very important engine parameter, more representative of engine size than cylinder bore and number of cylinders. Many engine indicators are closely related to displacement. Generally, the larger the displacement, the greater the engine's output power.
