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.

As a veteran driver with over a decade of experience, I can confirm that if your car window tint is too dark with light transmittance below the regulated standard, it may indeed fail the annual inspection. China has clear requirements for vehicle annual inspections - the windshield must have at least 70% light transmittance, the front side windows (driver and passenger) need over 50%, while rear windows have relatively looser standards but still can't be excessively dark. If you've installed dark tint, I recommend using a light transmittance meter for self-testing first (you can buy one online for just tens of RMB) to avoid wasting time at the DMV. I've seen cases where friends' cars got stuck at inspection stations due to overly dark tints, forcing them to either remove the film on the spot or replace it - costing hundreds extra and ruining their mood. My advice: always check the light transmittance label when selecting window film and don't just go for the cheapest option. While darker films offer better sun protection and heat insulation, they significantly reduce visibility and compromise safety, especially during night driving. Regular maintenance and attention to these details can prevent many troubles.

At what sub-zero temperature will No. 0 diesel freeze?

Theoretically, No. 0 diesel will freeze at 0°C. Here are the relevant details: 1. Diesel: The most important use of diesel is for diesel engines in vehicles and ships. Compared to gasoline, diesel has a higher energy density and lower fuel consumption rate. Due to its low energy consumption, some small cars and even high-performance vehicles have switched to diesel. 2. Freezing Point: The freezing point refers to the highest temperature at which the surface of the oil sample no longer moves under specified test conditions when cooled, expressed in °C. The freezing point and cold filter plugging point are important indicators of diesel's low-temperature performance.

What Causes Increased Engine Noise After Maintenance?

Possible reasons for increased engine noise after maintenance include: differences in quality between the new oil and the previous oil; insufficient viscosity or lubrication film thickness of the new oil; improper maintenance procedures or oil type mismatch with the vehicle model. Details about car maintenance are as follows: 1. Antifreeze usage tips: It's best to use antifreeze year-round. Besides its cooling and anti-freezing functions, antifreeze also cleans, prevents rust and corrosion, reducing radiator corrosion and protecting the engine. Pay attention to choosing the correct antifreeze color and avoid mixing different types. 2. Brake fluid usage tips: The performance of the braking system is closely related to brake fluid. When inspecting or replacing brake pads, discs and other hardware, don't forget to check if the brake fluid needs topping up or replacing.

How to Identify Pirelli Run-Flat Tires?

According to the tire brand, run-flat tires can be identified by special symbols following the specifications on the tire sidewall. Pirelli's run-flat symbol is R-F. Additional information is as follows: 1. Meaning of run-flat tires: Run-flat tires are technically called "Run-Flat System Tires," with the English abbreviation RSC. The inflated tire sidewall is the main part supporting the vehicle's weight, especially for tires with a larger aspect ratio (the ratio of tire height to width), where the sidewall is very "thick." 2. Advantages of run-flat tires: In the event of an impact or overheating causing a blowout during high-speed driving, they can still allow the vehicle to continue driving for a certain distance rather than exploding immediately.

Which charging piles can BYD use?

BYD can use all universal charging piles. The following is the relevant introduction of charging piles: 1. Waterproof capability: During the construction of charging piles, waterproof materials will be applied at the bottom of the charging facilities. This enables the lower part of the charging pile body (20~30 cm) to have waterproof and flood-resistant capabilities. 2. Charging pile inspection: Most charging piles use SMC fiberglass material, ensuring long-term outdoor use and resistance to complex weather conditions. 3. Charging interface: Even though waterproof materials are used for charging piles, it is recommended not to charge during rain. Some consumers worry that the charging interface may cause a short circuit due to rain exposure.

How to Diagnose a Faulty Crankshaft Position Sensor?

Crankshaft position sensor fault diagnosis mainly includes the following methods: 1. No high voltage, no fuel injection, and failure to start the car. 2. The engine fault light on the dashboard is illuminated. 3. If there are open or short circuits inside the sensor, signal lines, or engine control unit, the computer will be unable to receive the crankshaft position signal, and the engine will fail to start. Here are some additional details: 1. Function: The role of the crankshaft position sensor is to determine the position of the crankshaft, i.e., the angle of the crankshaft. 2. Method: It usually works in conjunction with the camshaft position sensor to determine the basic ignition timing.

What is the real fuel consumption of the 2.0T Highlander?

The actual fuel consumption of the 2018 Highlander 2.0T two-wheel drive 5-seater version is approximately 10.95L/100km, while the 2018 Highlander 2.0T two-wheel drive 7-seater version is about 11.09L/100km. Below is some extended information about the Highlander: "Triple Twin" Technology: The Highlander's 2.0T engine features "Triple Twin" technology, which refers to twin-scroll, twin-injection, and twin-cycle. The twin-scroll design allows more uniform airflow into the turbocharger, reducing hesitation. The twin-injection system combines direct injection and port injection, effectively reducing engine carbon buildup and improving fuel economy. The twin-cycle system utilizes both Atkinson and Otto cycles, enabling seamless switching between them for more direct power output and better fuel efficiency.
