What is the appropriate mileage for high-speed running?

New cars have speed limits when running at high speeds. Domestic cars generally range between 40-70 km/h, while imported cars are usually within 100 km/h. Below is extended information about vehicle speed: 1. Concept of vehicle speed: Vehicle speed generally refers to the driving speed of a car. It indicates the distance a car travels per unit of time, commonly measured in kilometers per hour or meters per second. 2. Spot speed: Spot speed is the instantaneous speed of a car passing a specific point on the road. The arithmetic mean of a set of spot speed observations is the average spot speed. Spot speed is widely used in traffic engineering as a basis for setting road design speeds, installing traffic control facilities, determining traffic management methods, implementing traffic improvement measures and their economic analysis, exploring speed trends of various vehicle types, and evaluating the effectiveness of road traffic facilities, traffic management, and improvement measures.

What is automotive compressor oil?

Compressor oil refers to a type of petroleum product used to lubricate the cylinder, valves, and piston rod seals of compressors. Classification of compressor oil: Compressor oil is generally categorized into two main types based on the base oil: mineral-based compressor oil and synthetic compressor oil. According to the compressor structure, it can be divided into reciprocating air compressor oil and rotary air compressor oil. Based on the nature of the compressed gas, it is classified into air compressor oil and gas compressor oil. Additionally, it can be categorized as light-duty, medium-duty, or heavy-duty compressor oil for air compressors. Functions of compressor oil: Air compressor oil is primarily used for lubricating the moving parts of the compressor cylinder and exhaust valves, while also providing rust prevention, corrosion resistance, sealing, and cooling effects.

Is it serious if the car hood is left open in the rain?

It can have an impact. When it rains with the hood open, water can enter the air filter through the gaps between the hood and headlights of the car. If the drainage valve's function is reduced, rainwater may enter the engine through the intake pipe, causing the engine to fail to start. For minor cases, you can remove the distributor cap, dry it with a tissue, and reinstall it. If there is severe water ingress, it requires professional repair. More relevant information is as follows: 1. Note: When the car hood is closed, the engine's air filter provides partial waterproofing. A small amount of water entering the engine's intake pipe is blocked by the air filter, preventing direct entry into the engine. If the car stalls in water, ensure the engine intake does not inhale more water while prioritizing personal safety, and park in a safe location. 2. Handling stalling due to water ingress: Open the engine hood, remove the cylinder wires, take out the spark plugs, then start the engine. Water in the engine cylinders will be expelled through the spark plug holes. Hold the key in the start position for 5 seconds, release, wait 10 seconds, then start the engine for 5 seconds. Repeat this process three times to effectively drain all water from the engine.

What Causes the Noise from Car Tires?

Most of the time, the noise from car tires is caused by stones stuck in the tire. Here is an introduction to the causes of noise from car tires: 1. Pattering sound: Nails or small stones are stuck in the tire. If the tire is deformed, it needs to be replaced; if stones are stuck, they should be removed. 2. Squealing sound: The brake pads are too thin. The car's brake pads need to be replaced. 3. Grinding sound: The tread is uneven, indicating a fault with the car tire. 4. Humming sound: The wheel bearing is making noise, producing a "humming" sound that increases with speed. 5. Popping sound: Mostly caused by deformed tread, bulges, severe wear, or insufficient tire pressure.

What Causes a Car to Start Easily When Cold but Not When Hot?

Main reasons include the following aspects: 1. Fuel injector leakage: While fuel injection is normal operation, leakage constitutes additional fuel supply. The more severe the injector leakage, the richer the air-fuel mixture becomes, leading to difficulty starting when hot. 2. Faulty carbon canister purge valve: During hot starts, fuel atomization is already normal and doesn't require additional fuel vapor. If the carbon canister continues supplying vapor to the intake, it creates an over-rich mixture, making starting difficult. 3. Intake air temperature sensor malfunction: This sensor adjusts fuel injection quantity. If faulty, it causes hard starting when the engine is hot.

What to do if the left rear door of Audi A6L cannot be opened from the outside?

Audi A6L rear door cannot be opened from inside or outside, which should be caused by the vehicle door lock block stuck. It is necessary to go to a 4S shop or a professional repair shop to find professional maintenance personnel to remove the door panel and open the door from inside. Most of this situation is due to the damage of the door cable. Here are more related introductions: Precautions: 1. Most of the rear doors of current cars have child safety locks. After locking the child safety lock, the door cannot be opened from the inside, only from the outside. If the door cannot be opened from both inside and outside the car, it is not a problem caused by the child safety lock. 2. Some cars may have a damaged lock block that affects the door opening. At this time, the lock block needs to be replaced. In daily use, pay attention to avoid the lock block contacting water, as frequent contact with water can easily cause the lock block to rust. When getting on and off the car on rainy days, you need to get on and off quickly and close the door quickly to avoid rain falling on the door lock block. 3. During daily maintenance, you should also pay attention to adding lubricating oil or grease to the lock block frequently to ensure that the lock block has good lubrication. Lubricating oil and grease also have anti-rust effects. In daily car use, pay attention to whether the door lock works normally. If it is not normal, repair it immediately. It is very dangerous to encounter an emergency situation where the door cannot be opened.
