Where to Find the Engine Number?

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's registration certificate. The engine number, like a person's ID number, represents each vehicle and contains crucial information about the vehicle. Engine model is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine, for a batch of identical products. It indicates information such as the manufacturer, specifications, performance, characteristics, technology, purpose, and production batch of the engine, including fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose passenger vehicles must be marked with the professional manufacturer, model, and production number as required. It is 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 engine models can be the same. The engine number, however, refers to the production number of the engine, where each engine has a unique number that cannot be duplicated. Composition of the Vehicle Engine Number: Front Part: Includes product series code, generation symbol, and regional or corporate code. Manufacturers can choose the corresponding letters as needed, but they must be approved and recorded by the industry standard regulatory body. Middle Part: Consists of symbols for the number of cylinders, cylinder arrangement type, stroke, and cylinder diameter. Rear Part: Composed of symbols for structural features and usage characteristics. Tail Part: Distinguishing symbol. When differentiation is needed due to improvements or other reasons within the same product series, manufacturers can choose appropriate symbols to indicate this. The rear and tail parts can be separated by a hyphen (-).

What Causes the Abnormal Noise from the Generator Belt?

The causes of abnormal noise from the generator belt are as follows: 1. The belt is too loose or has aged due to excessive mileage: Adjust the belt tension at a repair shop, or replace the belt directly if necessary. 2. Smooth contact surfaces between the belt and pulley: Check for damaged, seized, or loose bearings near the belt. If no issues are found, sand the contact surfaces of the belt and pulley with 100-grit sandpaper and apply a small amount of engine oil. 3. How often should the engine belt be replaced? This depends on the driving conditions. If the vehicle is often driven unloaded, inspect the belt at around 100,000 km and continue using it if no issues are found, replacing it at 130,000-140,000 km. If the vehicle is often driven under load, inspect the belt at 60,000-80,000 km and continue using it if no issues are found, replacing it at 100,000 km.

Is Dongfeng Venucia a Joint Venture Car?

Dongfeng Venucia is not a joint venture car. The Venucia brand originally had a promotional slogan stating that Venucia comes from Dongfeng Nissan, at which time the Venucia brand belonged to the joint venture's own brand. Today's Venucia has broken away from Dongfeng Nissan's embrace but now fully belongs to an independent brand, called Dongfeng Venucia, under the jurisdiction of Dongfeng Limited, sitting equally with Dongfeng Nissan. The Venucia brand can be viewed in two parts. Here, I refer to it as the old Venucia. For example, cars like the Venucia D50, R50, R50X, etc., are all products based on Dongfeng Nissan's old platform. They feature mature, stable, and reliable technology with relatively high cost performance and guaranteed quality.

What Causes Normal Low Pressure but Low High Pressure in Car Air Conditioning?

Car air conditioning with normal low pressure but low high pressure is caused by a malfunction or damage to the air conditioning compressor. This type of fault generally requires replacing the compressor with a new one. In a vapor-compression refrigeration system, the compressor is one of the main components. The compressor's role in the refrigeration system is to pressurize the gaseous refrigerant and then send it to the condenser for cooling and condensation. Regular checks should be performed on the compressor belt. If the belt surface and the pulley groove contact sides appear shiny, and there is a "squeaking" noise when starting the air conditioning, it indicates severe belt slippage, and both the belt and pulley should be replaced. If the belt is too loose, it should be adjusted; otherwise, it can lead to poor refrigeration in the air conditioning system. The main causes of compressor damage include: 1. Unclean air conditioning system, with particulate impurities being sucked into the compressor; 2. Excessive refrigerant or lubricating oil in the system, causing "liquid slugging" and damaging the compressor; 3. Compressor operating temperature is too high or running time is too long; 4. Compressor oil shortage, leading to severe wear; 5. The compressor's electromagnetic clutch slips, causing excessive friction temperature; 6. The compressor's power configuration is too small; 7. Defects in the compressor's manufacturing quality.

How to Reset the Tire Pressure of RAV4?

RAV4's tire pressure reset method is as follows: 1. Adjust the tire pressure to the standard level and start the engine. 2. Select the up arrow from the left side of the steering wheel, and a string of English letters will appear. 3. Then press the R button on the dashboard or a small black button on the dashboard, and "YES+, NO-" will appear. 4. Then select the plus sign on the right side of the dashboard, wait a few seconds to return, turn off the engine and restart it, and there will be no more prompts. The following is a detailed introduction about RAV4: Toyota RAV4 adopts a direct tire pressure monitoring system. The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure, and uses a wireless transmitter to send the pressure information from inside the tire to the central receiver module system, and then displays the tire pressure data of each tire. When the tire pressure is too low or leaking, the system will automatically alarm. After the tire pressure monitoring system alarms, the tire pressure should be checked and replenished as soon as possible. Confirm that the tire pressure is normal before continuing to drive. The tire pressure monitoring system will automatically reset after the vehicle has been driven for a certain distance.
