When driving in heavy fog, honking more is to attract the attention of others and avoid dangers. Heavy fog significantly reduces visibility, so sounding the horn several times can alert pedestrians and vehicles, preventing traffic accidents. Additionally, it's essential to turn on the fog lights and clearance lights to enhance safety. Precautions for Driving in Fog: Mental Preparation: Before driving, accurately assess the day's visibility to be well-prepared. The lower the visibility, the more cautious you should be. If visibility is less than 5 meters, it's considered extremely heavy fog, and it's best not to drive. Wait until the fog dissipates or lightens. Check Car Fog Lights: Before setting off, ensure the vehicle's fog lights are functioning properly and are installed according to national standards. When visibility is less than 1 kilometer, you must turn on the headlights and rear fog lights. Mind Your Speed: When driving in fog, strictly adhere to traffic rules and speed limits. Avoid speeding as poor visibility makes it highly prone to accidents. Overtaking and aggressive driving are strictly prohibited to prevent mishaps. The heavier the fog, the shorter the visible distance, and the lower the speed should be. Experts recommend: when visibility is less than 500 meters but more than 200 meters, speed should not exceed 60 km/h; less than 200 meters but more than 100 meters, speed should not exceed 40 km/h; less than 100 meters but more than 50 meters, speed should not exceed 30 km/h; and when visibility is less than 50 meters, maintain a speed of around 5 km/h. Maintain Distance: Drive at a low speed in fog, especially keeping a safe distance from the vehicle ahead. Avoid tailgating and unnecessary overtaking. Actively maintain a safe following distance to allow enough emergency space and reaction time if the vehicle ahead encounters problems. If you notice the vehicle behind is too close, lightly tap the brakes a few times (without actually braking) to illuminate the brake lights, reminding the following vehicle to keep an appropriate distance.

After driving for so many years, I find it really necessary to honk the horn more often in heavy fog. The fog obscures everything, reducing visibility to an astonishingly short distance, sometimes making it hard to even see the front of my own car. I honk to alert other drivers and pedestrians of my presence, as if silently saying, 'Be careful, I’m coming.' Without making some noise, people ahead or beside me might have no idea where I am, and if they suddenly appear, a collision becomes all too easy. For example, when turning at intersections, I often honk as a warning. Once, I nearly hit an electric bike rider, but because I honked early, he slowed down. This isn’t just about protecting myself—it’s also about considering others. Combined with turning on fog lights and driving at a reduced speed, the whole journey becomes much safer. In short, it’s a simple yet highly practical habit that significantly reduces the risk of accidents, especially on highways or narrow rural roads—definitely worth adopting.

What type of oil does DD250E use?

DD250E uses 10W40 grade engine oil. Application range: The number 10 indicates the minimum applicable temperature of the oil is -25°C, W stands for Winter, and 40 represents the high-temperature viscosity of the oil, with a kinematic viscosity of 14.5cst at 100°C. The preceding number denotes the oil's low-temperature fluidity - the smaller the number, the better the low-temperature fluidity. The number after W indicates the oil viscosity grade at 100°C. Importance of viscosity: Lubricating oil must have sufficient viscosity to prevent wear between moving parts and to form an oil film between moving components at various operating temperatures. However, the oil's fluidity shouldn't be so high as to affect engine startup, while generating minimal friction under continuous operation conditions. Using oil with excessive viscosity will increase component wear.

What is the fuel tank capacity of the Chery A3?

There are a total of 34 models of the Chery A3, classified as compact cars, all with a fuel tank capacity of 57 liters. The vehicle is equipped with five types of engines: 1.6L 126HP L4, 1.8L 132HP L4, 1.6L 126HP L4, 2.0L 139HP L4, and 1.6L 119HP L4. The transmission options include CVT continuously variable transmission, 5-speed manual, and 4-speed automatic with manual mode. The Chery A3 is available in both hatchback and sedan body styles. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the manufacturer is measured from the bottom of the tank to the safety level, with additional space from the safety level to the tank opening. This space ensures that the fuel can expand when temperatures rise without overflowing. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity. Fuel tank maintenance includes the following: Drain accumulated water and sediment from the tank, and check for leaks at fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, ensure that the ventilation holes are clear. The filter screen at the fuel filler neck should remain intact to prevent impurities from entering the tank and clogging the fuel lines during refueling. The sealing gasket on the fuel filler cap should also be intact to prevent fuel from spilling out while driving.

Which Honda cars have VTEC?

Honda vehicles, except for the 1.3L Fit which does not feature i-VTEC, all other models—whether from Dongfeng Honda, Guangqi Honda, or imported Honda—are equipped with this intelligent variable valve timing system. Honda's i-VTEC system is the English abbreviation for Honda's Intelligent Variable Valve Timing and Lift Electronic Control system. The latest Honda car engines are generally equipped with the i-VTEC system, which allows for continuous adjustment of valve timing and can also adjust valve lift. Below is an introduction to related content: 1. The working principle of the i-VTEC system is as follows: When the engine shifts from low to high speed, the computer automatically directs oil pressure to the small turbine inside the intake camshaft drive gear. Under this pressure, the small turbine rotates a certain angle relative to the gear housing, causing the camshaft to rotate forward or backward within a 60-degree range. This changes the timing of the intake valve opening, achieving the goal of continuously adjusting valve timing. 2. Honda's VTEC engine has long been known as the 'synonym for variable valve engines.' It not only delivers exceptionally strong horsepower output but also emphasizes low-speed operation with environmentally friendly exhaust standards and low fuel consumption. These entirely different characteristics occur in the same engine because it features two or even three different cam angles (cams) on a single camshaft. Small-angle cams are used at medium and low speeds, while high-angle cams are engaged at high speeds, resulting in two completely different performance output curves from the same engine.

What type of fire extinguisher is used in cars?

Fire extinguishers used in cars include dry powder extinguishers, ultra-fine dry powder extinguishers, carbon dioxide extinguishers, and water-based extinguishers. Vehicle fire extinguishers are specifically designed for automotive use and fall into two main categories: non-pressurized hanging ultra-fine dry powder automatic fire suppression systems for vehicles, and miniature pressurized hanging ultra-fine dry powder automatic fire suppression systems for vehicles. Different extinguisher materials have varying lifespans, with vehicle fire extinguishers typically valid for two years. If there is no expiration mark, the pressure gauge's needle in the green zone indicates usability. When the needle enters the red zone, it means the extinguisher lacks sufficient pressure and must not be used further, as expired extinguishers pose significant risks.

Can a novice driver's license be penalized with points?

Novice driver's licenses can indeed receive penalty points. From the date of issuance, any traffic violation can result in point deductions based on the severity of the offense. This applies equally during the probationary period - accumulating 12 points during probation will lead to license revocation. Penalty severity: Driver's license point deductions serve as penalties for traffic violations. Depending on the seriousness of the offense, points range from a minimum of 1 to a maximum of 12 per violation, with the counting cycle resetting at each license review period. Solutions for accumulating 12 points: If a driver accumulates 12 points within one cycle, they lose driving privileges. Typically, they must complete no less than 7 days of traffic safety education and pass an exam before their driving privileges can be restored.
