What is the gasoline engine oil grade chart?

Automotive engine oil grades range from SA to SN, with each increasing letter indicating a higher quality level. The functions of engine oil include the following three points: 1. Lubrication: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing shells. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. 2. Auxiliary cooling: Engine oil has a relatively low specific heat value and is located inside the engine, so it does not inherently have a cooling function. However, due to the heat energy generated by fuel combustion in the engine, during operation, engine oil can carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. The actual cooling is performed by the water outside the engine casing. 3. Anti-wear: Adding lubricants can reduce the friction coefficient, thereby decreasing frictional resistance, saving energy consumption, and reducing wear. Lubricants between friction surfaces can minimize wear caused by abrasive particles, surface fatigue, etc.

Where is the best place to install the rear camera of a dash cam?

The installation locations for the rear camera of a dash cam are introduced as follows: 1. Drilled installation: The advantage is a good camera angle, as it is positioned in the center, reducing the likelihood of dead angles and blind spots; the disadvantage is that drilling may damage the car body, and over time, the paint may peel off. 2. Screw fixation at the license plate light or direct clamping inside: The advantage is relatively simple installation and lower cost; the disadvantage is that screw fixation may damage the car body, prone to rust and falling off over time, and being exposed outside, it is not aesthetically pleasing and accelerates aging. 3. Sticking to the rear windshield: In this case, an additional rear recording camera for the dash cam needs to be installed. The advantage is easy installation, but the disadvantage is that it affects aesthetics, and due to the presence of the rear windshield, visibility may be unclear.

Can I get my car serviced outside of a 4S dealership?

It is possible to service your car outside of a 4S dealership, but it must be done at a legitimate service provider where you can verify the safety and reliability of the replaced parts. This serves as proof for potential warranty claims. If maintenance is performed at a certified repair shop with proper invoices issued, the 4S dealership will find it difficult to deny warranty coverage later by claiming the vehicle was not serviced at their facility. Introduction to car maintenance: 1. Car maintenance, also known as vehicle upkeep, refers to the regular preventive work of inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the vehicle. 2. Car maintenance primarily includes servicing the engine system, transmission system, air conditioning system, etc., aiming to keep the vehicle clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, and extend the service life.

What to Do When a Car's Motor Has No Power and Won't Start?

When a car's motor has no power and won't start, you can use the push-start method or the jump-start method. Below are the introductions to these two methods: 1. Push-start method (only for manual transmission cars): This method is commonly seen and is only applicable to manual transmission cars. It involves gathering several people to push the car to get it started. Once the car reaches a certain speed, engage the gear and quickly release the clutch pedal while pressing the accelerator. As soon as the engine starts, quickly press the clutch pedal again and control the throttle to prevent the engine from stalling, then slowly pull over to park. 2. Jump-start method: For this method, you first need another car with a charged battery nearby and a set of jumper cables. Bring the two cars close together, open the hood to locate the other car's battery, and connect the two batteries using the jumper cables. Follow the specific steps below carefully. If you're not confident, it's better to seek help from a professional or a specialized service.

How to Reset the Oil Maintenance Light on BAIC BJ80C?

BAIC BJ80C oil maintenance light can be reset using a fault diagnostic tool. Additional information: 1. Function of the car maintenance light: The original intention of the car maintenance light is to remind the owner to perform maintenance as soon as possible. Therefore, the owner should promptly go to the 4S shop for maintenance. After the maintenance is completed, the 4S shop will use a fault diagnostic tool to reset the maintenance light for the vehicle. 2. Definition of maintenance light reset: Most vehicle models have a maintenance light reminder function on the instrument panel. After driving a certain mileage or period of time, the LCD screen on the instrument panel will display a message prompting immediate maintenance. This means that the mileage or number of days the car has been driven has reached the time for replacing the three filters and oil. After replacing the three filters and oil, it is necessary to reset the system to allow the computer to re-memorize the next maintenance mileage or number of days, commonly known as maintenance light reset.

What are the reasons for the plunger pump failing to build up pressure?

The reasons for the plunger pump failing to build up pressure are: 1. The filter on the suction line is clogged; 2. The oil level in the hydraulic tank is too low; 3. The R-angle of the variable mechanism is too small, resulting in insufficient flow, combined with the effect of internal leakage, thus unable to continuously supply pressurized oil externally; 4. Severe damage to the contact surface between the distribution plate and the cylinder block, poor sealing, or initial poor sealing between the cylinder block and the distribution plate; 5. Severe wear between the plunger outer diameter and the cylinder bore, serious oil leakage, or insufficient driving power. The plunger pump is an important device in the hydraulic system, relying on the reciprocating movement of the plunger in the cylinder to change the volume of the sealed working chamber for oil suction and pressurization. The plunger pump has the advantages of high rated pressure, compact structure, high efficiency, and convenient flow regulation, and is widely used in applications requiring high pressure, large flow, and adjustable flow.
