Will Vehicle Polishing Affect the Paint?

As long as it is done properly, polishing will not cause significant damage. Apply wax evenly to a specific area of the paint surface and control the polishing machine speed between 1200-2000 RPM. Initially, apply moderate to high pressure on the polishing pad to polish the paint surface evenly. Observe the paint surface, and once the sandpaper marks are noticeably removed, reduce the pressure to eliminate wax traces and restore some gloss to the paint surface. After polishing, use a microfiber cloth to clean off any residual coarse wax and dust from the paint surface. Below is some information about polishing: 1. Polishing does not improve the dimensional accuracy or geometric shape precision of the workpiece but aims to achieve a smooth surface or mirror-like gloss. Sometimes, it is also used to remove gloss. Typically, a polishing wheel is used as the polishing tool. 2. A polishing wheel is usually made of multiple layers of canvas, felt, or leather stacked together, with metal discs clamping both sides. The wheel edge is coated with a polishing compound consisting of finely ground abrasives and grease evenly mixed.

How to Distinguish Between China 5 and China 6 When Buying a Car

The differences between China 5 and China 6 emission standards are as follows: Different Emission Standards: The China 6 emission standard is more than 30% stricter than China 5. Excluding the influence of driving conditions and testing, gasoline vehicles' carbon monoxide emissions are reduced by 50%, total hydrocarbon and non-methane hydrocarbon emissions are reduced by 50%, and nitrogen oxide emissions are reduced by 42%. Different Implementation Times: The China 5 standard was implemented nationwide on January 1, 2017, as the fifth stage of the national motor vehicle emission standard. The China 6 standard has been implemented since July 1, 2019. Different Principles: During the China 5 phase, diesel and gasoline vehicles had different emission standards. However, China 6 adopts a fuel-neutral principle, meaning the emission limits are the same regardless of the fuel type. Different Issuing Authorities: The China 5 standard was issued by the Ministry of Environmental Protection. The China 6 standard was issued by the Ministry of Environmental Protection and the General Administration of Quality Supervision, Inspection, and Quarantine. Different Letter Representations: China 5 is represented by "V," while China 6 is represented by "VI." Different Monitoring Requirements for Plug-in Hybrid Electric Vehicles: Compared to China 5, China 6 has improved monitoring requirements for plug-in hybrid electric vehicles, including energy storage systems, thermal management systems, brake regeneration, drive motors, generators, and other regulations. China 5 standard limits are as follows: Gasoline vehicles must not emit more than 1,000 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM (particulate matter) per kilometer driven. China 6 has two standards: China 6a and China 6b, as follows: China 6a standard limits: Gasoline vehicles must not emit more than 700 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 68 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 60 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 4.5 milligrams of PM per kilometer driven. China 6b standard limits: Gasoline vehicles must not emit more than 500 milligrams of carbon monoxide per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of non-methane hydrocarbons per kilometer driven. Gasoline vehicles must not emit more than 35 milligrams of nitrogen oxides per kilometer driven. Gasoline vehicles must not emit more than 3 milligrams of PM per kilometer driven. Affected by the China 6 emission policy, although China 5 vehicles can still be used normally without driving restrictions or license plate limitations, their resale value will be significantly impacted. For car owners, if they purchase a truck for freight transport with a loan, the vehicle's depreciation after paying off the loan is equivalent to the net profit earned during that period. A higher residual value means more profit for the owner. Therefore, from this perspective, China 6 vehicles, which have a longer lifespan and more road rights, are more advantageous.

Can You Put Car Perfume in the Car During Summer?

It is best not to place perfume in the car during summer. The hot and dry weather in summer increases the risk of fire. Especially when the air conditioning is on and the windows are closed, the car becomes a confined space, making it prone to explosion accidents. Many car owners tend to overlook these safety details, which can often lead to serious consequences. Here are some car maintenance tips: 1. Using perfume to mask odors inside the car is not a wise choice, as it does not completely eliminate the odors. 2. When cleaning the interior, avoid using low-quality foam cleaners, as they can leave a pungent smell and may also damage the car's interior. 3. During hot weather, try not to park the car in direct sunlight. Instead, park it in a shaded area or an underground parking lot.

Why is the speed low when the RPM is high?

There are several main reasons for high RPM but low speed: 1. The transmission is in a low gear: High vehicle speed requires high engine RPM to drive. 2. Clutch slippage: The clutch is installed between the engine flywheel and the transmission input shaft. When the clutch pedal is fully released, the power generated by the engine is transmitted to the transmission with nearly 100% efficiency after passing through the clutch. If the clutch slips, it will result in a slow acceleration phenomenon when stepping on the gas. 3. Instrument malfunction: For example, if the engine tachometer shows falsely high readings, or the speedometer displays a speed lower than the actual vehicle speed, it can also create a false impression. The specific situation should be identified and repaired accordingly.

Is Engine Warm-up Necessary in Summer?

Engine warm-up is not necessary in summer, and here are the reasons: 1. Engine warm-up is not required in any season because idling to warm up the engine is ineffective for fuel-injected engines and only useful for carburetor engines. 2. However, carburetor engines have been phased out, and modern cars use fuel-injected engines, so warm-up is no longer needed. Idling to warm up the engine not only fails to quickly raise the engine temperature but also leads to increased carbon deposits inside the engine. Prolonged idling also increases fuel consumption. 3. The correct driving method is to start driving immediately after starting the engine, just avoid running the engine at excessively high RPMs during the initial driving period. This approach protects the engine and reduces wear.

Can You Add Ethanol to a Car?

You can directly add ethanol to a car, but it may cause severe damage to the vehicle, increase fuel consumption, and reduce the engine's power performance to varying degrees. Ethanol gasoline can corrode non-ferrous metals and rubber materials in components such as the fuel tank and carburetor to different extents. Here are some methods to handle a car running out of fuel: 1. Call for assistance. If your car runs out of fuel in the city, there's no need to panic. The current rescue network is quite extensive, and a single phone call can bring professional rescuers to help you. Therefore, calling for assistance should be the first choice when encountering vehicle issues. 2. Look for a tow truck. If environmental factors make the above methods difficult to implement, towing might be a relatively conservative solution. All you need is to keep a tow rope in the car at all times.
