I am aCar modificationLovers, although ChinesecarThe modification market is not developed, but the German Brabus and Hamann modification manufacturers have officially entered the Chinese market in 2006 and 2011. Can new cars modified by these modification plants be licensed in China?
At present, China's car modification market is not as prosperous as abroad, but my country's policy restrictions on car modification have been relaxed a lot compared to before. Consumers can completely modify their vehicles within the scope of the policy. At present, foreign refitting manufacturers that have officially entered the Chinese market must also abide by relevant Chinese policies and regulations. Vehicles refitted and sold by them can be licensed in China, such as the Bosu version of Smart.
Recently, the rain has been relatively frequent. I found that the brake discs of my high 6 will rust after being parked for a period of time. May I ask the rusty brake discs?Braking SystemDoes it matter? How should it be handled?
Since brake discs are mostly made of cast iron, when the vehicle is parked in a humid environment, some rust marks will be formed on the surface of the brake discs, and these rust marks will more or less affect the normal operation of the brake system. We should remove it as soon as possible. If there is only a slight rust on the surface of the brake disc, then we can use continuous braking to remove it; if the rust is more serious, we do not recommend the above method of stepping on the brake to remove the rust.Because there is more rust, the surface of the brake disc will be uneven. In this case, braking will cause the body to shake, and the driver can clearly feel itBrake pedal, Steering wheel and body abnormalities. At this time, it will be difficult to remove the rust. Even i

Even if the brake disc is barely "polished", it will cause abnormal wear of the brake disc, and there will still be jitters. If you want to completely solve this situation, you need to go to the repair shop to remove the brake disc, polish the rust with sandpaper, check the surface of the brake disc for any abnormalities, and then conduct a road test after proper installation to ensure that there is no abnormality. . If there is still jitter, then it needs to be polished and leveled or replaced according to the situation.
I have a 2007 Polo car. The repairman said that the car was used for maintenance some time ago.Three-way catalytic converterIt's time to clean, why does the three-way catalytic converter need to be cleaned? How to clean?
As we all know, the three-way catalytic converter can convert CO, HC and NOx three gases into harmless gases through redox reactions.But the gasoline we use every day generally contains high sulfur and phosphorus content, which willOxygen SensorIt forms compounds with the surface of the three-way catalyst; when driving on a congested road in the city, the stop-and-go situation will cause insufficient fuel combustion, and the product will adhere to the surface of the three-way catalyst; clean the fuel injector,ThrottleWhen the intake duct is maintained, carbon deposits and particulate matter will pollute the three-way catalytic converter. These factors will cause the three-way purification function to be reduced or even fail, and the vehicle cannot meet the exhaust emission standards. At this time, the three-way catalytic converter needs to be cleaned.
Three-way catalytic converters need to be cleaneddetergent, The three-way cleaning agent enters the combustion chamber through the intake vacuum tube. After combustion, a high-temperature oxidation environment is formed around the three-way catalyst. The sulfur, phosphorus and other compounds attached to the surface of the three-way catalyst and gasoline are incompletely burned through the oxidation-reduction reaction. The product is converted into SO2, CO2 and other gases to be discharged, so as to achieve the purpose of restoring the activity of the three-way catalyst. The ternary cleaning agent can fully burn clean in the combustion chamber, so it will not cause any harm to the engine.
Hello, editor teacher, I am a second year student, I like racing very much, especially F1 competition, but I do not understand the Chinese name of F1 "Formula One", please explain to the editor teacher.
F1 is the abbreviation of "Formula One", translated into Chinese is "Formula One". The original meaning of "Formula" in English is "conventions, conventions, guidelines, schemes", which is translated as "equation" here, which means "rules, restrictions". Since all the specifications of the participating vehicles are manufactured in accordance with established terms, such as unified engine displacement and power, they are called "formula racing." At present, there are many formula events around the world, and the top one is F1. Since 5 years, F3000 has been replaced by GP2 events. In addition, the GP3 series and F3 belong to the lower level of formula competition.
Don't panic when driving with a flat tire
Due to the high temperature in summer,tireThe probability of a puncture at high temperatures also increases.The owner of the car should control the direction in daily driving and don’t lettireCrash into obstacles on the side of the road, so as not to damage the tires and cause safety hazards. In case of a puncture during driving, do not slam on the brakes, as this will easily cause the vehicle to flick or even roll over. The correct way is to tightly control the direction of the steering wheel by hand, shift the gear from high gear to low gear, and then step on the brake slowly to make the vehicle decelerate as smoothly as possible until it stops.
