It is caused by the corrosion and aging of oil seals. Here are the specific details: 1. Cause: More than 90% of oil leakage issues are caused by the corrosion and aging of rubber sealing components. Over time, rubber seals lose their plasticizers, causing them to shrink, harden, and lose elasticity. Prolonged aging may even lead to fractures, resulting in oil leakage. 2. Solution: If your car experiences oil leakage, you can use a non-dismantling repair method by applying Marty DS. Its high-efficiency plasticizers can penetrate or be absorbed by the seals, causing them to re-expand and regain elasticity. This compensates for the wear between the shaft and the sealing lip, ensuring a tight fit between the sealing lip and its shaft, thereby resolving the oil leakage issue.

Is driving at 80 km/h on a national highway with a speed limit of 70 km/h considered speeding?

Driving at 80 km/h on a national highway with a speed limit of 70 km/h already constitutes speeding. Here is some information about national highways: 1. Introduction: National highways refer to major trunk roads with national political and economic significance. 2. Composition: (1) Trunk roads connecting the capital to the political and economic centers of provinces, municipalities, autonomous regions, and cities with a population of over 300,000. (2) Trunk roads leading to major ports, railway hubs, and important industrial and agricultural production bases. (3) Trunk roads connecting large and medium-sized cities to important foreign trade ports, open cities, historical cities, and major scenic areas. (4) National defense trunk roads of significant importance. These roads form the framework of the national highway network.

How often should the engine oil be changed for a China V diesel vehicle?

China V diesel vehicles typically require an engine oil change every 60,000 kilometers. Below is some relevant information about diesel: 1. Introduction: Diesel is a light petroleum product, a complex mixture of hydrocarbons (carbon atoms ranging from approximately 10 to 22). It serves as fuel for diesel engines. Diesel is primarily produced by blending diesel fractions obtained from processes such as crude oil distillation, catalytic cracking, thermal cracking, hydrocracking, and petroleum coking. It can also be derived from shale oil processing and coal liquefaction. Diesel is categorized into light diesel (boiling point range approximately 180~370℃) and heavy diesel (boiling point range approximately 350~410℃). It is widely used in large vehicles, railway locomotives, and ships. The most important application of diesel is in diesel engines for vehicles and ships. 2. Differences from gasoline: Compared to gasoline, diesel has a higher energy density and lower fuel consumption rate. Due to its lower energy consumption, some small cars and even high-performance vehicles have switched to diesel.

What is the correct way to connect jumper cables to a car battery?

The correct way to connect jumper cables to a car battery is: 1. Clamp one end of the red cable to the positive terminal of the dead battery. 2. Connect the other end of the red jumper cable to the positive terminal of the working car's battery. 3. Attach one end of the black cable to the negative terminal. 4. Connect the other end of the black cable to the negative terminal of the working car's battery, or to an unpainted metal part of the car body or engine mount, to complete the connection. Additional information: Start the working vehicle and let it idle for a while to charge the dead battery. Ensure all electrical devices in the dead vehicle are turned off, as they can draw power from the engine during startup, requiring a higher starting current.

What are the reasons for a China V diesel vehicle not consuming urea?

Here are the reasons why a China V diesel vehicle may not consume urea: 1. Reason one: Check whether the urea nozzle is crystallized and blocked, and whether the control unit has no power supply control for the nozzle. 2. Reason two: The scientific name of automotive urea is Diesel Exhaust Fluid (DEF). It is used in diesel engines. It is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition is 32.5% high-purity urea and 67.5% deionized water. 3. Reason three: Check whether the control unit has power supply settings for the nozzle. Generally speaking, damage to the power supply harness can lead to open circuits, short circuits, or broken circuits, affecting the normal operation of the post-treatment components.
