Where is the car engine number located?

The engine number is generally found on the outer surface of the engine block, or on the vehicle's nameplate, the nameplate inside the engine compartment. You can also check the engine number on the car purchase invoice; the factory certificate includes the engine number; for commercial vehicles, the operation permit can be used to query the engine number; the vehicle purchase tax payment certificate contains the engine number; the public security authority's registration records have the engine number; the vehicle insurance card lists the engine number; it can also be found below the windshield directly in front of the driver's seat. 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 individual vehicle. It stores very important information about the vehicle. The engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry or enterprise practices, and the engine's attributes, for a batch of identical products. It indicates information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, including details like fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles are marked with the professional manufacturer's name, model, and production number as required. 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 product line, and multiple engines can share the same model. The engine number, however, refers to the production number of the engine, with each engine having a unique number that cannot be duplicated. Composition of the car engine number: Front section: Includes the product series code, generation symbol, and regional or enterprise code, which the manufacturer can choose as needed, but must be approved and recorded by the industry standard's regulatory body. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and cylinder diameter. Rear section: Comprises symbols for structural features and usage characteristics. Tail section: Distinguishing symbols. When differentiation is needed within the same series due to improvements or other reasons, the manufacturer selects appropriate symbols to indicate this, with the rear and tail sections possibly separated by a hyphen.

Why does an electric car not move in rainy days despite having power?

The reasons why an electric car does not move in rainy days despite having power are as follows: Water ingress or poor contact in the controller: When the controller gets wet, it cannot receive power, causing the electric vehicle to fail to move or the rear wheel to lock; if the controller gets wet, it is necessary to promptly open the controller, dry it with paper or a cloth, wipe the circuit board with alcohol, and finally let it dry before sealing and testing it. If it still does not work, replace the controller immediately. Poor line contact: Loose battery connection wires or poor contact in the power lines. Check whether the battery terminals are corroded or loose. Water ingress in the battery: Insufficient power in the electric vehicle, water ingress in the battery can lead to insufficient discharge output current.

Which has a higher grade, A3B4 or A5B5?

A5B5 has a higher grade than A3B4. The specific details are as follows: Certification Standards: Engine oils A3B4 and A5B5 are two testing and certification standards for automotive lubricants set by the European automobile manufacturing industry, with A5B5 being the highest grade under this certification standard. Among them: 'A' refers to gasoline engines for passenger cars, 'B' refers to diesel engines for passenger cars, and the number indicates quality. The larger the number, the higher the quality and grade. Information about engine oil is as follows: Engine oil: It is the lubricating oil used by the engine, composed of base oil and additives. Function: With a density of approximately 0.91×10³ (kg/m³), engine oil can lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. It is known as the 'blood' of the car. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil, imparting certain new properties, making them an important part of lubricating oil.
