How Often Should the Intake Valve and Throttle Body Be Cleaned?

What lights to use when meeting on narrow roads or bridges at night

It is best to alternately use high and low beams when driving through narrow roads or bridges at night. According to Articles 48, 51, and 58 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China", when meeting another vehicle at night, switch to low beam when the oncoming vehicle is more than 150 meters away. When a motor vehicle passes through an intersection controlled by traffic lights at night, use low beam when turning. When a following vehicle is driving close to the vehicle in front in the same direction, use low beam. Drive with low beam on well-lit roads. When a motor vehicle passes through sharp curves, slopes, arch bridges, crosswalks, or intersections without traffic light control at night, alternately use high and low beams to signal. When driving in low visibility conditions such as fog, rain, snow, dust, or hail, turn on the headlights, position lights, and rear lights. Turn on fog lights and hazard warning flashers when driving in foggy conditions. Do not turn on fog lights when driving in normal weather conditions at night, as fog lights can be very dazzling to oncoming drivers. Do not use high beam when driving in fog, as the upward-angled high beam light gets diffusely reflected by the fog, creating a blinding white haze in front of the vehicle that actually reduces visibility.

What is the average fuel consumption per 100 kilometers for a sedan?

The average fuel consumption per 100 kilometers for a sedan is approximately 1.68 liters. Below are the fuel consumption calculation formula and tips for reducing fuel consumption: Fuel consumption calculation formula: Fuel consumed ÷ Distance traveled × 100 = Fuel consumption per 100 kilometers. The data on fuel consumed is relatively difficult to obtain, so the initial data is usually taken from a full tank. After driving a certain distance, the tank is refilled, and the fuel amount provided by the gas station is used as the accurate data. Tips for reducing fuel consumption: The economic speed is the speed at which the car consumes the least fuel when driving in direct gear or overdrive. When a car travels on the same road, different speeds result in different fuel consumption. Therefore, there is a specific speed at which fuel consumption is the lowest. Thus, the car should be driven at a moderate speed in direct gear or high gear to save fuel.

Should Regular Cars Use 92 or 95 Octane Fuel?

The selection of fuel grade should be based on the compression ratio of the car's engine. The appropriate fuel grade for the vehicle is usually indicated on the inside of the fuel tank cap. If it specifies 92 octane fuel, then use 92. If it specifies 95 octane fuel, then use 95. Whether the fuel is labeled 92 or 95, the number represents the fuel's anti-knock performance. The higher the fuel grade, the better the anti-knock performance, but this has little to do with the quality of the gasoline itself. It is not necessarily true that higher fuel grades are always better, as many car owners commonly believe. For naturally aspirated engines, 92 octane fuel is generally recommended. Higher-grade fuel has better anti-knock performance but burns relatively slower, which can lead to a higher compression ratio in the engine, resulting in reduced power and increased temperature. For turbocharged engines, the manufacturer usually recommends fuel with a grade of 92 or higher. Using 95 octane fuel not only helps achieve higher torque at low speeds but also reduces engine vibration and noise.

How Long Can a Car Be Parked Before It Has Difficulty Starting?

If a car is parked for about half a year, it may experience difficulty starting. If the car is left unused for an extended period, it is best to start it once a month and let it run for half an hour each time to recharge the battery. A car battery is a consumable part, and the more frequently a car is driven (especially on long trips), the longer the battery's lifespan tends to be. Conversely, cars that are frequently parked and often discharge without sufficient recharging tend to have shorter battery lifespans. Below are some related details: Reasons for starting difficulty: After a car has been parked for a long time, difficulty starting is usually due to a depleted battery. The primary cause of battery depletion is the age of the car battery. Typically, a car battery has a lifespan of two to three years. If the battery exceeds this lifespan, the car is highly likely to experience battery depletion after just two or three days of inactivity. Solutions: The best way to prevent battery depletion in a car that is parked for long periods is to start it regularly, allowing the car's built-in alternator to recharge the battery.

How Often Should You Wash Your Car?

It is most appropriate to wash your car once every 10 days. Washing your car too frequently can accelerate paint oxidation, while not washing it for extended periods can speed up paint aging and damage, leading to premature vehicle deterioration. Below are some precautions to consider when washing your car: Avoid Using Random Detergents: Do not use laundry detergent, stain removers, or low-quality soap when washing your car. These detergents contain alkali, which can strip the protective oils from the paint surface and accelerate aging. Therefore, it is generally recommended to avoid adding detergents when washing your car. Avoid Using High-Pressure Water Jets: Excessive water pressure can damage the car's paint surface. If there is stubborn dirt or mud on the car, soak it with water first before rinsing. Use a dispersed water stream for spraying. Avoid Using Water Other Than Soft Water: This includes hot water, alkaline water, and hard water, as these can damage the paint. Washing with hard water can leave marks and a filmy residue on the car's surface after drying.

What are the typical length, width, and height of a car?

Generally, the length of a sedan ranges between 3800mm and 4300mm, the width between 1600mm and 1800mm, and the height between 1400mm and 1600mm. Length: Length is the most influential parameter affecting a car's purpose, functionality, and ease of use. Therefore, vehicle classes are typically categorized by length. A longer body means more longitudinal usable space. Width: Width primarily impacts seating space and maneuverability. For passenger cars, if three seats arranged side by side are to provide a spacious feel (mainly sufficient shoulder room), the width generally needs to reach 1.8 meters. Height: Vehicle height directly affects the center of gravity (handling) and interior space. Most sedans are under 1.5 meters in height, significantly lower than the natural sitting height of a human body. This is mainly to lower the vehicle's center of gravity, ensuring stability during high-speed cornering to prevent rollovers.
