How to Drive a New Energy Vehicle?

New energy vehicles should be driven correctly as follows: 1. Electric vehicles, like gasoline cars, also have the most economical driving speed. Keeping the electric vehicle within the economical speed range as much as possible during driving can effectively extend the driving range. 2. Unless absolutely necessary, avoid sudden acceleration by pressing the accelerator pedal hard, as an instant speed increase will raise power consumption. At the same time, accurately predicting the state of the vehicle ahead can help the driver operate the car more smoothly. Slowing down by coasting without pressing the accelerator is definitely more economical than braking sharply. The limited electrical energy should be converted into the car's kinetic energy as much as possible, rather than being wasted as heat by the braking system. 3. Currently, mainstream electric vehicles are equipped with a kinetic energy recovery system, which can convert excess kinetic energy during coasting into electrical energy and recharge the battery. When this system is activated, the vehicle will produce a certain degree of drag sensation. Different brands and models have varying levels of kinetic energy recovery intensity, resulting in different deceleration forces.

Within visibility of 50 meters, how much distance should be maintained from the vehicle ahead?

When visibility is less than 50 meters in heavy fog, the following distance should be more than 50 meters. However, since visibility is only 50 meters, you should follow the vehicle based on not being able to see the vehicle ahead. When driving in fog, turn on the fog lights and hazard warning lights, and also turn on the clearance lights. If visibility is below 50 meters, the speed should be controlled within 20 kilometers per hour. Under these conditions, it is necessary to exit the highway at the nearest opportunity. The following are introductions for other visibility conditions: 1. Visibility less than 200 meters: Turn on the fog lights, low beam lights, clearance lights, and front and rear position lights. The speed must not exceed 60 kilometers per hour, and maintain a distance of more than 100 meters from the vehicle ahead in the same lane. 2. Visibility less than 100 meters: Turn on the fog lights, low beam lights, clearance lights, front and rear position lights, and hazard warning flashers. The speed must not exceed 40 kilometers per hour, and maintain a distance of more than 50 meters from the vehicle ahead in the same lane.

Why is the tire noise of BMW X3 loud?

BMW 3 Series uses run-flat tires, so the tire noise is more noticeable when the car is running. Run-flat tires are inherently hard and have no inner tube, which indeed causes significant tire noise. Run-flat tires: The technical name for run-flat tires is "puncture-proof tires," abbreviated as RSC. The sidewall of an inflated tire is the main part that supports the weight of the vehicle, especially for tires with a larger aspect ratio (the ratio of tire height to width). The sidewall is very "thick." In severe cases of a "blowout," the sidewall can instantly collapse, causing the tire to lose support immediately. This results in an abrupt change in the vehicle's center of gravity, particularly for front-wheel-drive cars where a front tire blowout can lead to an instant shift in the center of gravity, potentially causing the vehicle to lose control. Check tire pressure: If the pressure is insufficient, it can be inflated, so it is essential to carry an emergency air pump. Additionally, if possible, the tire can be completely vacuumed and then filled with nitrogen, which has the effect of reducing tire noise. Remove foreign objects from the tires: If abnormal wear is found on the tire tread and the tire is nearing the end of its service life, consider replacing the tire.

How to resolve the P0015 trouble code?

P0015 trouble code can be resolved by changing the engine oil of the car. P0015 indicates that the B camshaft position actuator timing is retarded, which may be caused by dirty engine oil leading to mechanical wear. The worn metal particles can enter the actuator, resulting in the trouble code. The causes of P0015 include incorrect timing setting of the B intake/left/front camshaft, mechanical binding causing the camshaft to be excessively retarded, or the actuator valve stuck in the open position. In short, it refers to retarded timing. The "B" camshaft must be the "exhaust," "right," or "rear" camshaft. Left/right and front/rear are determined from the driver's perspective. The first group refers to the group including cylinder 1, and the second group is the group opposite to the first. When the P0015 trouble code appears in a car, it is likely due to a faulty VVT actuator. You can visit a 4S shop or a professional repair shop to clear the trouble code. When a car has a trouble code, it is necessary to quickly look up the code to obtain the corresponding explanation and solution. When clearing the trouble code, the method specified for the car model must be followed. Do not randomly disconnect the battery negative cable to clear the trouble code, as this may cause the car's control center computer to malfunction or lead to certain features not working properly.

What Causes the Central Brake Light Warning?

Central brake light warning failure may be caused by a blown brake light fuse or a faulty brake light switch. Below is relevant information about brake lights: 1. Classification: Automobile brake lights can be categorized by position into three types: rear brake lights located at the back of the vehicle; dashboard brake lights, also known as brake indicators; and high-mounted brake lights. Based on materials used, they are divided into two types: gas automobile brake lights and LED automobile brake lights. 2. Base Models: Rear brake light base model: P21/5W, also known as BAY15D or 1157. This base model features a dual-filament structure with both brake warning and position functions. When serving as a brake light, it operates at 21W; when functioning as a position light, it operates at 5W, with the position light remaining constantly on. 7443 base brake light: W21/5W, also referred to as 7443. This base model also has a dual-filament structure with brake warning and position functions. The brake function operates at 21W, while the position function runs at 5W and remains constantly on.

What is the function of sealing oil?

For hydrogen-cooled generators, sealing rings are installed at both ends to prevent hydrogen leakage. The sealing oil system serves to supply oil to these sealing rings while simultaneously separating hydrogen, air, and moisture from the oil, thereby purifying it. Operation and maintenance methods: 1. Oil temperature and pressure: Activate the water side of the sealing oil cooler to maintain oil temperature between 35°C and 49°C. As the generator gas pressure increases, ensure the balance valve and differential pressure valve function properly; the outlet pressure of the hydrogen-side oil pump should normally not be lower than 0.6MPa. 2. Check the generator foam elimination tank and liquid level detection for oil presence: Monitor the differential pressure of the air-hydrogen side sealing oil filter. If the automatic oil discharge and replenishment of the sealing oil tank fails, manually adjust it. When hydrogen pressure drops below 0.1MPa and the sealing oil tank discharge is obstructed, use the hydrogen-side oil pump outlet discharge method. 3. If the balance valve adjustment fails: Switch to manual adjustment. When the oil-hydrogen differential pressure drops to 0.056MPa, the high-pressure sealing standby oil will automatically engage to maintain the oil-hydrogen differential pressure at 0.056MPa.
