Is 35% Light Transmittance for Side and Rear Windows Very Transparent?

1 Answers

Side and rear window light transmittance of 35% is not very transparent. National standards require that the light transmittance of the front windshield and the side windows in the driver's mirror viewing area should not be less than 70%. Since 35% light transmittance for window film is neither high nor low, it does not significantly affect nighttime driving visibility and can provide good privacy protection. Light transmittance of car front windshield: According to relevant regulations, the driver's compartment of motor vehicles must ensure forward and side visibility. The visible light transmittance of the front windshield and the glass areas outside the windshield used for the driver's viewing zone must not be less than 70%. In addition, no reflective sunshade film is allowed on any window. Definition of light transmittance: Light transmittance, as the name suggests, refers to the percentage of light that passes through. The higher the light transmittance, the lighter the color of the film, and the clearer the vision of the driver and passengers. The Ministry of Transport stipulates that the light transmittance of front windshield film must be higher than 70%.

What causes thick sludge at the oil filler port?

Sludge is a residue left behind by prolonged use of mineral oil, especially in engines with oil additives, which are more prone to sludge buildup. If the sludge is excessively thick and you wish to avoid disassembling the engine, you can remove the valve cover and oil pan, soak them in diesel, and then scrub with gasoline. Below are detailed explanations: 1. Causes: Adopting the bad driving habit of "high gear at low speed." Prolonged idling and low-speed driving. Using gasoline with inadequate purity and quality. 2. Effects: Difficulty in cold starts, failure to reach the specified idle speed when cold, and in severe cases, stalling during cold idle. Low idle speed after the engine warms up. Reduced engine power, sluggish acceleration, and increased fuel consumption. Deterioration in engine exhaust emissions, which also shortens the lifespan of spark plugs, oxygen sensors, and catalytic converters. Carbon deposits can cause the piston rings to stick, affecting their sealing performance, leading to increased oil consumption, engine oil burning, and a shortened engine lifespan.

What does the M gear in Audi A4L mean?

M gear is the manual mode of an automatic transmission vehicle, and "M+" and "M-" are the gear shift controls. The number of gears depends on the type of the automatic transmission. For example, an 8-speed automatic transmission means the M gear has 8 gears. When switching to M gear, you can shift gears up or down by controlling "M+" and "M-". Scenarios for using M gear: 1. Driving up or down steep slopes: First, shifting to manual mode when going up a steep slope can fully utilize the engine's power output. Shifting to manual mode when going down a steep slope allows the engine to control the speed, reducing the need for prolonged braking and helping to avoid overheating of the brake discs to some extent. 2. Overtaking: When overtaking, you can also switch to manual mode and downshift to gain greater traction, achieving the goal of quick overtaking more effectively than stomping on the accelerator (D gear). 3. Poor road conditions: When starting on rainy or slippery roads, using D gear (default 1st gear) may cause the wheels to slip. Using M gear and shifting to 2nd gear reduces engine torque, effectively lowering the probability of slipping.

Will there be a fine for renewing a driver's license that has been expired for eight months?

There will be no fine for renewing a driver's license that has been expired for eight months. The renewal process is the same as the normal renewal process. The motor vehicle driver should bring the required materials and apply for renewal at the vehicle management office where the driver's license was originally issued. The vehicle management office will process the renewal within one working day after the review is passed. In addition to applying for renewal at the vehicle management office, you can also apply for renewal through the following methods: Renewal via the "Traffic Management 12123" APP. Download the "Traffic Management 12123" APP, then select Service Center -- Expired License Renewal Service -- Fill in the information. The new license is generally delivered by mail. Visit the "Police-Medical-Post" service point at a postal business hall to handle the renewal. The entire process, from registration and medical examination to the production of the new license, takes only half an hour. Currently, only a few cities have opened this service, such as Hangzhou.

Will Tire Repair Fluid Corrode Wheel Hubs?

Tire repair fluid can corrode wheel hubs. Below are the relevant details: 1. Automatic Tire Repair Fluid: This type of repair fluid does not require removing the tire for patching; it can seal a puncture in just 3 seconds. Once added, it can be used for an extended period. If a tire is punctured while driving, the fluid automatically repairs it without the need to stop, completely revolutionizing traditional manual tire repair methods. It has strong repair capabilities, capable of sealing holes as small as micro-pores and as large as 6mm. 2. Wheel Hub: The wheel hub is the rotating part of the wheel steel inside the tire, connected by pillars to the wheel core, which is the metal component mounted on the axle that supports the tire. It is also known as the rim, steel ring, or wheel. Wheel hubs come in various types based on diameter, width, manufacturing method, and material.

What symptoms will a car show if the engine oil viscosity is insufficient?

Generally, several symptoms may occur: The oil warning light on the dashboard will illuminate. The engine temperature tends to run higher, and valve tapping noises may be heard. Knocking sounds can be detected within the engine noise. Below are detailed explanations: 1. Oil warning light on: When the oil indicator lights up on the dashboard, immediate oil replenishment is required. 2. Consequences of driving without sufficient oil: Firstly, lubrication effectiveness will significantly deteriorate. Secondly, in severe cases, lack of lubrication may lead to engine seizure. The less oil remains, the more severe the consequences. When restarting the engine, dry or semi-dry friction may occur between cylinders and pistons, accelerating component wear. Moreover, starting resistance increases substantially, making ignition more difficult.

What is the normal water temperature for an Audi A4?

The normal water temperature for an Audi A4 is around 90°C. If it exceeds 100°C, the fan will turn on, and if it exceeds 120°C, the dashboard will issue a warning. The reasons for high water temperature are as follows: 1. Insufficient coolant: Coolant leakage or a lack of coolant can cause the engine's water temperature to rise. In this case, you should check the coolant level and add more if necessary. After a few days, check the level again to see if it has dropped significantly. If it has, you need to locate the source of the leakage. 2. Faulty cooling fan: If the cooling fan is faulty, the heat generated during high-speed operation cannot be effectively transferred to the coolant, affecting heat dissipation and causing the coolant temperature to rise, leading to issues like overheating. 3. Faulty water pump: Water pump issues can include seized bearings or damaged impellers. Seized bearings are relatively rare, but damaged impellers, such as cracked impellers or impellers loosening from the pump shaft, can slow down the coolant circulation, making the engine prone to overheating.
