What happens if you don't change the engine oil for a long time?

If you don't change the engine oil for a long time, the following effects will occur: 1. Reduced sealing effect: High-quality oil with appropriate viscosity can effectively block the gap between the cylinder block and the piston, preventing gas leakage. If the oil is not changed for a long time, it will become watery and lose its sealing effect. 2. Reduced lubrication effect: The lubrication system is crucial to the engine, affecting its performance and service life. If the oil is not changed for a long time, the lubrication effect will be greatly reduced. 3. Reduced cooling effect: The heat absorption and thermal conductivity of oil are much higher than water. If the oil deteriorates seriously, the heat dissipation function will be greatly reduced. 4. Increased wear of mechanical parts: If the car does not change the oil for a long time, the oil will become ineffective and deteriorate. The oil will not only fail to protect but also increase the wear and damage to mechanical parts. 5. Corrosion of internal parts: If the oil is not changed for a long time, there will be a lot of impurities, such as iron filings, which will not only cause wear but also corrode internal parts. 6. Further damage to the engine: It will further damage the engine, similar to the harm of lack of oil. Lack of oil causes direct damage, while not changing the oil depends on whether the oil deteriorates and its performance declines. Damage occurs after deterioration and performance decline, and the process is relatively longer, causing slow damage. 7. Higher maintenance costs: Not changing the oil and oil filter in time or using inferior oil will lead to the production of sludge. When there is too much sludge in the engine, the oil pump will have difficulty maintaining sufficient oil pressure, causing engine failure and higher maintenance costs.

How to Deal with Unstable Steering Wheel Control During Subject 3 Driving Practice?

When practicing the test content for Subject 3, if you experience unstable steering wheel control, it is necessary to report the issue to the instructor. An unstable steering wheel can pose safety hazards during training, leading to inaccuracies in the student's handling feel and increasing the difficulty of the test. Relevant information about Subject 3 is as follows: 1. The road test content for Subject 3 generally includes preparation before starting, light simulation, straight-line driving at the start, gear operation, lane changing, etc. 2. To learn the test content for Subject 3, you can use simulation software on mobile or computer devices. During the Subject 3 test, no less than 20% of the candidates will be randomly selected for night driving tests.

What Causes No Signal in Car Reversing Camera?

Reasons for no signal in car reversing camera are as follows: 1. When the car is just started, it may interfere with the operation of the reversing camera. You can try restarting to see if the situation improves. It could also be electromagnetic interference from other electrical devices in the car. Try turning off the radio or music player before restarting. 2. The probe of the reversing camera may be damaged or the photosensitive signal of the chip may be blocked due to prolonged use. You can remove the camera and connect it to someone else's navigation system to test if the camera is faulty. 3. Poor line contact can cause the reversing radar to work intermittently. We can check the connection between the reversing radar lines and the vehicle's installation wiring to see if there is any loose connection. 4. If the reversing camera on the car is part of a navigation and reversing camera integrated system, it may be that the navigation card slot is damaged, causing the reversing camera function to fail.

The Function and Principle of the Throttle Valve?

The throttle valve has the following 4 functions: 1. Enhancing power through acceleration or deceleration; 2. Correcting the intake function via its self-regulation; 3. Controlling the operation of the engine assembly: The idle switch inside the engine is at work; 4. Controlling the flap: By working with sensors, it regulates the intake volume to boost power. Principle of the throttle valve: The throttle valve is a controllable valve that regulates the air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter above and the engine block below, it is often referred to as the throat of the car engine.

What tools are included in the Santana spare tire?

In the Santana spare tire compartment, you will find a spare tire, a jack, a triangular warning sign, and a tow hook. Below is some relevant information: 1. Regularly inspect the spare tire. During routine maintenance or before long-distance trips, few car owners check their spare tires, and some unprofessional repair shops often overlook this. Spare tire inspection mainly involves checking tire pressure and for any wear or cracks. It is advisable to replace the tire before the tread wears down to the wear indicator line. 2. Avoid storing oil products with the spare tire. The main component of a tire is rubber, which is highly susceptible to erosion by various oil products. Car owners often store lubricants and other oil products in the trunk. If these oils come into contact with the tire, they can cause swelling and corrosion, significantly reducing the tire's lifespan.

What should the indoor car air conditioning temperature be set to in winter?

In winter, the most suitable temperature setting for car air conditioning is between 18℃ and 20℃. Here is relevant information about car air conditioning: 1. The function of car air conditioning is to adjust and control the temperature, humidity, air cleanliness, and airflow inside the vehicle to an optimal state. It also provides a comfortable environment for passengers, reduces travel fatigue, creates good working conditions for the driver, and serves as a crucial ventilation device for ensuring safe driving. 2. Car air conditioning consists of components such as the compressor, condenser, evaporator, expansion valve, receiver-drier, and piping. 3. Car air conditioning generally includes cooling devices, heating devices, and ventilation devices. These combined systems make full use of the limited space inside the vehicle, featuring a simple structure and ease of operation.
