Audi's mild hybrid system does not require charging. Mild Hybrid System: A mild hybrid system refers to a vehicle's powertrain configuration. Vehicles equipped with this system generally have a starter-generator that can provide some kinetic energy via a belt (this is the essence of mild hybrid), and the system includes an additional 12V lithium-ion battery to power this starter-generator and receive generated electricity. Principle of Mild Hybrid System: The 48V mild hybrid system essentially upgrades the standard 12V voltage to 48V, allowing the electrical system to support more electrical components, such as engine start-stop systems, adaptive cruise control, and other driver assistance systems. The 12V mild hybrid system is essentially a simplified version of the 48V mild hybrid, building upon the traditional 12V electrical system. It does not have the additional 48V battery found in 48V mild hybrids but replaces the conventional 12V lead-acid battery with a 12V 11Ah lithium-ion battery. The motor is also much smaller compared to the 48V system, but it can still provide 1kW of power to the engine, reducing fuel consumption by 0.4L/100km.

Is Break-in Necessary for a New Car?

Break-in is necessary for a new car. Here are the relevant materials about new car break-in: 1. A newly purchased car requires break-in. The quality of the break-in will have a significant impact on the car's lifespan, safety, and fuel economy. 2. The most important aspect during the break-in period is to limit the engine's RPM. Excessive RPM during break-in may increase the risk of piston ring damage. 3. The break-in period is divided into three stages: initial, middle, and final: 1) Initial stage: Generally, the maximum speed should be controlled at around 40km/h. 2) Middle stage: Under good road conditions, the maximum speed can be increased to 60km/h. 3) Final stage: The speed can then be raised to around 80km/h. During the break-in period, maintain moderate speed - neither too high nor too low, as excessively low speed will increase fuel consumption.

Can a car with very dark window film pass the annual inspection?

Window film that is too dark cannot pass the annual inspection. Before the annual inspection, the window film on the vehicle must be removed, otherwise it will not pass. During the annual inspection, the windshield of the vehicle should be intact, with no cracks or damage in the driver's field of vision, and no mirror-reflective sunshade film should be applied to any windshield. The following is an introduction to the annual inspection of vehicles: The annual inspection, also known as the annual check, is a safety inspection conducted every year or every two years on the vehicle, including a comprehensive check of the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, license plate installation, etc. Before the annual inspection of the vehicle, it is necessary to check whether the vehicle has any traffic violations. If there are any violations, they must be dealt with before the annual inspection, otherwise the annual inspection cannot be processed if the violations are not resolved.

What is the function of vehicle antifreeze?

Vehicle antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as preventing freezing in winter, boiling in summer, and offering year-round protection against scale and corrosion. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with longer mileage, the replacement cycle is shorter. Since the driving conditions of each vehicle vary, the replacement should be based on actual usage. Check the condition of the antifreeze; if it is found to be insufficient, replenish it promptly. If suspended matter, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced immediately, and the system should be cleaned. What is antifreeze: The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze functionality. Antifreeze can prevent the coolant from freezing and expanding, which could crack the radiator or damage the engine cylinder block or head during cold winter parking.

What are the pros and cons of small-displacement turbocharging?

Advantages include strong power, fuel efficiency, and a power delivery method more suited to urban roads. Disadvantages include pressure drop at high RPMs, insufficient power reserve during high-speed acceleration, and higher maintenance costs. I. Advantages of small-displacement turbocharged engines: 1. Increases engine intake air volume without raising displacement, thereby boosting power without significantly increasing fuel consumption. 2. Small-displacement turbocharged engines provide higher torque at low RPMs, making their power delivery more suitable for city driving. 3. Small-displacement turbocharged engines have great tuning potential—some engines can gain 40-50 horsepower with just a software tune, without any hardware modifications. II. Disadvantages of small-displacement turbocharged engines: 1. To reduce turbo lag, many small-displacement turbocharged engines use small-inertia turbos, which can lead to pressure drop at high RPMs. 2. At high speeds, small-displacement turbocharged engines lose their advantage, as naturally aspirated engines perform better. 3. The power delivery of small-displacement turbocharged engines is not linear. 4. Maintenance costs for small-displacement turbocharged engines are slightly higher than for naturally aspirated engines, as they require higher-quality engine oil.

How Much Antifreeze Should Be Added to a Vehicle?

Car antifreeze should be added according to the remaining amount of antifreeze in the car. If there is no remaining antifreeze at all, it should be 6 to 7 liters, which generally applies to newly assembled vehicles. For vehicles that have been drained and refilled, it is usually 5 to 6 liters. How to determine if antifreeze is lacking: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to a lack of antifreeze, although it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), you should not continue driving and need to add antifreeze promptly. Check the water level scale markings on the antifreeze bottle. The antifreeze level should normally be between the maximum and minimum water levels. Whether antifreeze is lacking depends on the scale. If the antifreeze level is below the minimum water level, it indicates a lack of antifreeze.

What are the consequences of insufficient vehicle coolant?

Insufficient vehicle coolant can have the following impacts on the car: In summer, if the car lacks coolant, it may cause the engine to overheat and trigger an alarm, and in severe cases, lead to cylinder scuffing. In cold climates, it may cause the engine or radiator to freeze and crack, resulting in engine failure. It also affects the radiator's heat dissipation efficiency, failing to achieve the necessary cooling effect. The inability to circulate properly can generate high temperatures, and in severe cases, may cause engine burn-out. How to determine if coolant is insufficient: Observe the coolant warning light on the dashboard. If it lights up, it is likely due to insufficient coolant, although it could also be caused by excessively high temperature inside the cylinder. Check the coolant reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving; add coolant promptly. Check the water level scale markings on the coolant bottle. The normal coolant level should be between the maximum and minimum water levels. To determine if coolant is insufficient, check the scale. If the coolant level is below the minimum mark, it indicates a lack of coolant.
