Problem mainly lies in the brackets, English brackets should be used, input should be in uppercase English, and the vehicle number must be correctly written. Below is relevant information: Introduction: Engine model is an identification code assigned by engine manufacturers to a batch of identical products according to relevant regulations, enterprise or industry conventions, and engine attributes. It represents information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine. For example, fuel type, number of cylinders, displacement, and brake power.
