How to solve the problem of unstable idle speed and frequent stalling of BYD F3?

What to Do If Diesel is Accidentally Added to Gasoline?

Here is the relevant introduction about mistakenly adding the wrong fuel: 1. Adding diesel to a gasoline car: The vehicle may experience shaking, black smoke from the exhaust, or even fail to start. If driven forcibly, the entire fuel system could be damaged, and the engine might even be ruined. Solution: Contact a specialized repair shop as soon as possible to clean the fuel tank and fuel system, followed by a comprehensive engine inspection. Avoid starting the engine to prevent further damage. 2. Adding gasoline to a diesel car: Initially, the vehicle may start, but after driving for a while, noticeable unstable idling, abnormal engine noises, and white smoke from the exhaust will appear. Compared to adding diesel to a gasoline car, if detected early and the fuel is replaced immediately, the engine can still function. Solution: Find the nearest repair shop to replace the gasoline immediately. It is also advisable to clean the fuel tank and fuel system and replace the fuel filter.

What Lights to Use on Unlit Roads?

When driving at night on roads without streetlights or under poor lighting conditions, you should turn on the headlights, clearance lights, and tail lights. Here is some relevant information: 1. Legal Basis: According to Article 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China," when driving at night without streetlights, under poor lighting conditions, or in situations of low visibility such as fog, rain, snow, dust, or hail, motor vehicles must turn on the headlights, clearance lights, and tail lights. However, when a following vehicle is driving close to the vehicle in front in the same direction, high beams should not be used. In foggy conditions, motor vehicles must turn on the fog lights and hazard warning flashers. 2. High Beams Are Only for Special Circumstances: When driving at night, it is usually sufficient to use low beams for illumination, as they do not shine directly into the eyes of oncoming drivers, making them relatively safer.

What are the precautions for operating a bench drill?

Precautions for using a bench drill: 1. Check whether the main power switch of the bench drill is turned on, and whether the work, fixture, and cross arm on the drill press are tightly clamped. 2. After inspection, operate according to the safety operation procedures. 3. When using the bench drill, wear labor protection equipment properly, fasten the cuffs, and gloves are strictly prohibited. Female workers or employees with long hair should wear work caps. 4. Check whether the bench drill is well grounded. 5. When drilling brittle metal materials, wear protective goggles to prevent chips from injuring people. 6. Before operation, the power switch of the bench drill must be in the off state. Carefully inspect the bench drill body, especially the parts with large stroke force, to ensure that the bench drill has no defects and does not operate with problems. 7. Wear protective equipment and goggles.

How to Handle a Car That Has Been Used for 15 Years?

Here are the methods for handling a car that has been used for 15 years: 1. Mandatory scrapping of the car: From certain perspectives, this has some rationality. First, there are safety requirements. After a car has been used for a certain number of years and traveled a certain distance, factors such as wear and tear may affect the safety of the car. Another factor is that in the early stages of the automotive industry's development, appropriate and necessary mandatory updates were beneficial for the growth of the automotive industry. 2. The new version of the "Mandatory Scrapping Standards for Motor Vehicles" stipulates: (1) Non-operational small, micro passenger cars and large cars will no longer have a 15-year limit but will be scrapped based on mileage. Vehicles that reach 600,000 kilometers will be "guided to scrap." If a private car is well-maintained and has not reached 600,000 kilometers after 15 years, it can still continue to be driven. (2) Vehicles that do not undergo annual inspections for three consecutive inspection cycles after the expiration of the inspection period or fail the annual inspection for three consecutive cycles and thus do not obtain the motor vehicle inspection qualification mark should be mandatorily scrapped. (3) The inspection cycle for motor vehicles will also vary depending on the model and condition of the vehicle. Typically, small private cars require inspection every 2 years within the first 6 years, every year from 6 to 15 years, and every half year after 15 years.

What Should Be Done During the First Car Maintenance?

During the first maintenance of a new car, the primary tasks include changing the engine oil and replacing the three filters (oil filter, air filter, and fuel filter). 1. Changing the engine oil: Engine oil is the lubricant for the engine's operation. It plays a crucial role in lubricating, cleaning, cooling, sealing, and reducing friction in the engine. It significantly reduces wear on engine components and extends their service life. You can determine whether the oil needs to be changed by observing if its viscosity has changed, if its smell has faded, or if its color has altered. 2. Oil filter: The oil filter is a component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, moisture, and additives. During engine operation, metal shavings from friction between parts, impurities from inhaled air, and oil oxides are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circulation system, it will adversely affect the engine's performance and lifespan. 3. Air filter: The engine inhales a large amount of air during operation. If the air is not filtered, the dust in it can accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can also cause severe cylinder scoring. The air filter's role is to remove dust and particles from the air, ensuring that sufficient, clean air enters the cylinder. 4. Fuel filter: The fuel filter provides clean fuel to the engine by filtering out moisture and impurities from the gasoline. This optimizes the engine's performance and provides the best protection for the engine.

What are the precautions for driving in rainy weather?

Here are the precautions for driving in rainy weather: 1. Prevent tire skidding: The ground is wet in rainy weather, and the friction of rubber tires is greatly reduced when wet, which can easily cause tire skidding. Therefore, avoid sudden braking when turning; it's best to decelerate in a straight line before entering the curve. In case of an emergency requiring sudden braking, stay calm—either steer to avoid or brake in a straight line. Avoid braking and swerving simultaneously, as it won't help. 2. Reduce fogging: If it suddenly starts raining while driving, the temperature drops, and the windshield temperature also decreases. The water vapor inside the car condenses into fog on the windshield, obstructing visibility. In this case, turn on the air conditioning and direct it toward the windshield. 3. Master driving through water: Be cautious on roads with standing water, generally driving straight at low speed without stopping randomly. If the water level exceeds the exhaust pipe, detour. 4. Purchase water damage insurance: Car insurance includes water damage coverage, but most taxis do not have it. Hence, they often avoid working in heavy rain. For private cars, it's advisable to have water damage insurance to claim compensation from the insurer if the car gets flooded. 5. Avoid swerving: Some people, annoyed by rain after washing their cars, tend to swerve around small puddles, which can confuse following vehicles about the driving path and lead to rear-end collisions.
