Does Sun Exposure Affect White Car Paint in Summer?

Sun exposure does affect white car paint in summer. The ultraviolet rays in sunlight can ultimately cause oxidation of the car's coating, leading to aging, discoloration, and cracking of the paint. Here are specific details about car paint: 1. Paint Oxidation: Since car paint is constantly exposed to the air, over time, the surface paint will gradually oxidize and turn yellow. Especially in summer, the strong ultraviolet rays accelerate the oxidation of the coating. 2. Long-term Lack of Washing: The car body can easily accumulate dust, mud spots, and other dirt. Rainy or snowy weather can leave water marks, and parking near restaurant exhaust vents or barbecue stalls can cause oil smoke particles to adhere to the paint. If these contaminants are not cleaned promptly, they can penetrate the paint layer.

What to Do When the Car Door Handle Freezes?

If the car door handle is frozen, you can use a hair dryer to melt the ice on the handle or use warm water to rinse off the ice on the door. During winter when temperatures are low, it is advisable not to park the car outdoors. If there is water accumulation in the door gaps, it is very likely to freeze. Once the door handle is frozen, avoid using excessive force to open the door, as this can damage the handle and potentially other components like the door handle lock. Car door handles are typically made of 30% glass fiber-reinforced PA6, with the outer shell made of a PCABS blend, and the structural components behind made of 30% glass fiber-reinforced PP. The shapes, colors, and functions of these car door handles and lock modules are highly diverse.

What is the fuel tank capacity of the Hongqi H5?

The fuel tank capacity of the Hongqi H5 is 55 liters. The tank's capacity is fixed, and it is not advisable to overfill it as it poses safety risks and can damage the fuel gauge. Automobile fuel tanks are categorized by material into steel tanks and aluminum alloy tanks. With the development of new materials, the rust prevention of steel fuel tanks has become a significant quality concern. The Hongqi H5 is a model from Hongqi, which largely follows the design of the Hongqi B-Concept concept car. It features an inverted trapezoidal front grille connected to the headlights, with vertical chrome-plated decorative strips embedded inside. This car is equipped with a 1.8T engine, with a rated power of 131KW and a torque of 250NM, paired with a 6AT transmission.

How to Remove Oil Film from Car Windshield?

To remove oil film from the car windshield, you can use a dedicated oil film cleaner. Spray the cleaner evenly on the glass and wipe it with a car wash towel or sponge. Toothpaste can also remove oil film as it contains abrasive particles that provide a polishing effect. Apply it evenly to clean the pores on the glass surface and eliminate the oil film. Oil film on the windshield is mostly found on cars that have been driven for several years, and it is rare for new cars to have this issue. While car paint maintenance is commonly practiced, windshield care is often neglected. Airborne impurities can corrode both the car paint and the windshield glass. Therefore, when performing coating or glazing treatments, it is advisable to also apply a protective film to the windshield to effectively prevent oil film corrosion.

How many cylinders does the Envision have?

The Envision is equipped with a four-cylinder engine, which is one of its strengths in terms of performance. The 2.0T turbocharged engine delivers a maximum horsepower of 260 PS and a maximum torque of 400 NM, giving it a competitive edge among vehicles in the same class. A four-cylinder engine, also known as a four-cylinder power unit, is a machine capable of converting one form of energy into another more useful form. The Envision continues Buick's tradition of high-end interior quality and introduces a newly designed 10-inch high-definition touchscreen to enhance the technological feel. The vehicle also features front-row multi-function seats, rear sliding seats with adjustable backrest angles, a large split central storage box, a heated steering wheel, and a two-piece oversized panoramic sunroof.

What to Do When the Battery Doesn't Hold Charge?

There are two methods to repair a battery that doesn't hold charge: 1. Adding water, but only deionized water or purified water can be added. Tap water must not be used as it can damage the battery. 2. Using positive and negative pulse charging to depolarize the battery, followed by a complete discharge. This cycle should be repeated three times. The battery, also known as an accumulator, uses lead-calcium alloy for its grid framework. This results in less water decomposition during charging and lower water evaporation. Additionally, its sealed structure releases minimal sulfuric acid gas. Compared to traditional batteries, it offers advantages such as no need to add any liquid, easy connection to terminals, and longer charge retention time.

What is the Principle of Crankcase Ventilation?

Crankcase ventilation principle: During engine operation, high-pressure combustible mixture and burned gases from the combustion chamber may leak into the crankcase through the gap between the piston assembly and the cylinder to varying degrees, causing blow-by. The blow-by consists of unburned fuel vapor, water vapor, exhaust gases, etc., which degrade the performance of the engine oil. To prevent excessive crankcase pressure and extend the service life of the engine oil, crankcase ventilation is essential. Crankcase ventilation includes natural ventilation and forced ventilation. Modern gasoline engines commonly use forced crankcase ventilation, also known as the PCV system. Natural ventilation involves installing a ventilation pipe on the crankcase, equipped with an air filter screen. When the pressure inside the crankcase increases, the gases leaking into the crankcase are expelled through the ventilation pipe.
