Shell is a Dutch brand. The Royal Dutch Shell Group of Companies, also translated as "Shell", is currently the world's largest oil company, headquartered in The Hague, Netherlands, and London, UK. It was formed by the merger of Royal Dutch Petroleum and the UK's Shell. The following are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a sealing ring between the piston ring and the piston, reducing gas leakage and preventing external pollutants from entering. 3. Anti-rust: Lubricating oil can adhere to the surface of parts to prevent contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, this load is transmitted through bearing lubrication, cushioning the impact load. 5. Cleaning: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, flushing away dirt generated on the working surfaces of the parts through the flow of lubricating oil.

What is the repair method for a self-priming pump that keeps running without stopping?

Self-priming pump that keeps running without stopping repair method is: promptly check whether there is water leakage in the outlet pipe, locate the leakage position, repair or replace it to ensure normal operation. The working principle of the self-priming pump is: before starting the pump, fill the pump casing with water first. After starting, the high-speed rotation of the impeller causes the water in the impeller channel to flow toward the volute, creating a vacuum at the inlet, which opens the inlet check valve, allowing air in the suction pipe to enter the pump and reach the outer edge through the impeller channel. Precautions for using a self-priming pump include: 1. After the entire pump body is fixed, steel pipes can be used to connect to the pump's inlet, and the bottom valve of the self-priming pump needs to be perpendicular to the horizontal plane to ensure normal use later; 2. To prevent electric shock accidents, necessary protective measures should be taken.

What are the reasons for the car body crossing the line during reverse parking?

The reasons for the car body crossing the line during reverse parking include: 1. Releasing the clutch too quickly during the test; 2. Forgetting to shift into forward gear after entering the parking space; 3. Failing to adjust the rearview mirror position before the test, resulting in inadequate visibility; 4. Difficulty in controlling the clutch after switching cars, leading to panic; 5. Discovering the car is improperly positioned upon entry and needing to readjust. Reverse parking is a key assessment point in the driver's test, which involves maneuvering the vehicle correctly into a parking space from both sides while in motion. There are three common types of reverse parking: the first is the 'non-character' type, commonly found in large shopping centers; the second is the 'linear' type along the roadside, also known as parallel parking; the third is the less common 'diagonal' type of reverse parking.

What to Do When the Coolant Light Comes On?

The methods to handle when the coolant light comes on are: 1. Pull over immediately and turn off the engine as soon as possible; 2. After the engine cools down, open the front hood to inspect; 3. Visit a 4S store promptly to have professionals add coolant. Coolant, short for antifreeze coolant, is composed of water, antifreeze, and additives. Based on the antifreeze component, it can be categorized into alcohol-based, glycerol-based, and ethylene glycol-based. The functions of coolant are: 1. To prevent the coolant from freezing and expanding in cold seasons, which could crack the radiator and damage the engine cylinder block; 2. To prevent corrosion of metal parts and aging of rubber components; 3. To reduce scale formation, avoiding clogging of circulation pipes and affecting the cooling system's heat dissipation function; 4. To prevent the engine water temperature from becoming too high, ensuring the engine operates at the proper working temperature; 5. To provide lubrication for the water pump thermostat and other components.

How to Handle Rear Wheel Skidding to the Right on Muddy Roads?

When encountering rear wheel skidding to the right on muddy roads, the correct handling method is to steer the wheel in the same direction to straighten the vehicle body and slowly drive out of the muddy section. Methods to get a car unstuck from mud include: 1. If the car is only slightly stuck, applying full throttle may help the vehicle power through the mud pit; 2. Releasing some air from the tires to increase friction between the tires and the ground; 3. Placing bricks or stones around the mud area and using them as leverage when applying full throttle; 4. Using a jack to lift the stuck wheel and then driving the car out of the predicament. Methods to handle tire skidding are: 1. For rear-wheel-drive vehicles: release the accelerator pedal, steer the front wheels straight, then gently press the accelerator to return to the correct driving direction; 2. For front-wheel-drive vehicles: gradually release the accelerator pedal while steering towards the intended direction, then straighten the wheel and accelerate gently to continue driving.
