How Long Does It Take from Car Purchase to Delivery?

It depends on the car model, and the time varies between imported and domestic vehicles. If the 4S store has inventory, you can drive it away immediately. For domestic cars, the longest wait is half a month. For imported cars without stock, it takes at least three months. Below are some precautions when taking delivery of the car: Regarding vehicle documents: Purchase invoice, certificate of conformity, vehicle type approval certificate, vehicle registration certificate, warranty certificate, vehicle user manual, and new car delivery confirmation form. If the 4S store handles the license plate registration and insurance, you will also need to obtain the original insurance policy, insurance invoice, compulsory traffic insurance invoice, vehicle and vessel tax invoice, purchase tax invoice, tax payment certificate, and compulsory insurance label from the salesperson. Vehicle inspection: For the exterior, check the paint, production date of the window glass, tires, trunk, and engine. For the interior, focus on inspecting car functions such as lights, wipers, windows, rearview mirrors, dashboard, air conditioning, audio system, etc.

How long does it take to drive after replacing the windshield?

Some windshield adhesives are quick-drying and can solidify in about 1-2 hours, while others may take around 6 hours. Currently, the standard adhesive on the market requires approximately 24 hours to ensure safe driving. Below is an introduction to windshields: Function: Laminated glass consists of a transparent adhesive plastic film sandwiched between two or three layers of glass, combining the toughness of plastic with the hardness of glass to enhance the glass's resistance to shattering. Tempered glass is made by quenching ordinary glass to create internal stress, thereby strengthening the glass. When impacted and shattered, tempered glass breaks into small, blunt-edged fragments, reducing the risk of injury to passengers. Maintenance tips: Choose the appropriate windshield washer fluid. When the windshield surface becomes blurry, cleaning it with suitable washer fluid can significantly improve clarity. If you notice excessive glare at night, wiping the glass with washer fluid can help. Additionally, during high-speed driving or in dusty conditions, washer fluid is consumed quickly, so it's important to refill it promptly.

What are the advantages of multi-point fuel injection?

The advantages of multi-point fuel injection are high efficiency, fuel economy, and mature technology, as detailed below: High combustion efficiency: Compared to traditional single-point fuel injection technology, multi-point fuel injection has electronic fuel injectors installed in each intake manifold, forming a mixture in the intake pipe. The mixture is more uniform, so the combustion efficiency is higher than that of traditional single-point fuel injection. Higher combustion efficiency means the engine's output power is greater. More economical and fuel-efficient air-fuel ratio control: Compared to traditional single-point fuel injection technology, multi-point fuel injection technology can adopt sequential injection, so the control of the air-fuel ratio is higher and more precise than traditional methods. This reduces toxic emissions and is more economical and fuel-efficient. Mature technology: Whether compared to traditional single-point fuel injection technology or newly developed direct injection technology, multi-point fuel injection technology has been developed for some time and is superior to the former two in terms of engine break-in and economy.

What Are the Hazards of Filling Up the Fuel Tank in Summer?

Filling up the fuel tank can lead to poor fuel efficiency and high risks. The details are as follows: Hazards of filling up the fuel tank: Worse Fuel Economy: Studies show that for every 100kg increase in weight, a car's fuel consumption rises by 6-8%. If manufacturers didn't consider this, why not increase the tank capacity further? More fuel means greater vehicle mass, resulting only in higher fuel consumption. Increased Health Risks: Overfilling the tank causes liquid fuel to flow directly into the charcoal canister, damaging its vapor absorption function. Evaporated fuel gases (containing carcinogens like benzene) are released, posing long-term health hazards to passengers. Clogged Ventilation Holes: The small vent holes on the fuel tank cap are used to balance internal and external pressure. Once clogged by fuel, negative pressure builds up inside the tank. The fuel pump fails to draw fuel, leading to unstable fuel supply—causing the car to jerk or even fail to start.

Which mode is more fuel-efficient for a car with manual-automatic transmission?

For a manual-automatic transmission, the D (Drive) mode is the most fuel-efficient. If operated correctly, the M (Manual) mode can also be very fuel-efficient. Below is an introduction to the manual-automatic transmission: Introduction: A manual-automatic transmission combines manual and automatic shifting modes. This transmission integrates the advantages of both automatic and manual transmissions, minimizing power loss in the shifting system. The manual mode allows drivers to freely adjust gears and RPM according to their preferences, providing a thrilling and sporty driving experience with enhanced driving pleasure. Manual mode acceleration and overtaking techniques: Using manual mode for overtaking. Drivers familiar with automatic transmissions know that acceleration in automatic mode is not as responsive as in manual mode, especially when overtaking. In D mode, the speed does not increase rapidly even with heavy throttle input, as the transmission shifts sequentially. However, with a manual-automatic transmission, the situation is different. When accelerating to overtake, simply switch to manual mode without braking—just shift the gear lever into manual mode. Then, pressing the throttle firmly will result in a rapid speed increase, making overtaking smooth and effortless, with responsiveness comparable to a manual transmission.
