Which one has a stronger start than a manual or automatic transmission? When asked this question, most people's first reaction is: Of course, manual transmission is more powerful. The reason is: racers all use manual gears, and their 100km/h acceleration time is shorter than that of automatic gears; otherwise, racers don't need manual gears! This reason suddenly sounds plausible, but the answer will surprise you. Let's find out together. First, try to find two such cars, the engine displacement is the same at 1.8T, the idle speed is 800r/min, the tires and the body are the same, one is automatic, and the other is manual. The manual gear is in 1st gear, the automatic gear is set to D gear, and the brake pedal is released simultaneously; which vehicle starts more powerfully? Assume that the torque output by the engine at 800r/min idle speed is 20N.m (just an assumption, although...

Many people may take the words "run-flat tires" for granted and feel that as long as the car is equipped with such tires, they can sit back and relax. Are run-flat tires that magical? Of course, this is not the case. If run-flat tires mean they won't blow out, wouldn't ordinary tires have no market at all? What is a run-flat tire? The scientific name of run-flat tires is "run-flat tires," and RSC is its English abbreviation. A run-flat tire does not mean that it can prevent a puncture or air leak. Its "magic" lies in the hard sidewall of the tire. When the tire has no air pressure, the vehicle will lose its balance immediately, and the tire will suddenly fall out of the wheel hub. The most significant advantage of run-flat tires is that in the case of tire leakage, even if the air pressure in the tire...

In the cold winter, many car owners were very anxious when they suddenly encountered a car that could not catch fire. The first reaction was that the car was broken. Most cars fail to catch fire due to human factors, and you can solve them in many cases. This article will spread it to everyone. 1. If you get up in the morning and the temperature is very low, the car's ignition fails. First, try to turn on the key and add the accelerator. Without oil, we continuously step on and release the accelerator when turning the key. When the body shakes, and the engine is about to start, release the accelerator so as not to slam the accelerator and cause damage to the vehicle. 2. In winter, the power consumption of the battery increases significantly, but the capacity decreases at low temperatures, which can easily cause insufficient battery power....

The brake pedal travel is too large, the braking effect is slow, the braking efficiency is very low or even lost, and the braking distance increases. Cause of failure: 1. Insufficient brake oil pressure. (The brake master cylinder lacks oil, the brake pipe is broken, the oil pipe joint is leaking, and the oil circuit is blocked); 2. There is air in the braking system; 3. The free travel of the moving pedal or the brake clearance is too extensive, the brake shoe friction plate is in poor contact, and the wear is severe or oily; The bowl is aged and damaged. Troubleshooting: 1. Depress the brake pedal continuously; for example, the pedal gradually rises and has a springy feeling but stops after a while. When the pedal is still low, there is air in the brake system, and the brake system should be exhausted at this time. 2. The...

Although car use is about performance and practicability, for car owners, if the paint of the car is damaged and the appearance is damaged, it will also affect the mood of users. In order to ensure the beautiful appearance of the car for the majority of car lovers, the editor introduces several methods for treating car paint problems here. Different diseases also need different treatment measures. Oxidation of car paint Perennial exposure to sunlight is the main reason for shortening the life of car paint. Ultraviolet rays in sunlight can eventually cause the oxidation of car coatings. If there are still water droplets hanging on the body when it is exposed to the sun, the rate of oxidation will be much faster. If it is slightly oxidized, it can be removed with wax. Once the oxidation is serious, it must be ground and polished. Cracked paint Cracked paint can easily...

The usage of glass cleaning fluid will be significantly reduced in winter, but it should not be ignored. If you are not careful, the cleaning equipment will be damaged. Some car owners use water instead of water in other seasons with high consumption, but those substitutes often freeze in winter, so they cannot be used in winter. Experts suggest that in an environment below zero degrees Celsius in winter, the anti-freezing winter glass cleaning solution should be replaced, or an appropriate proportion of alcohol should be added to it to lower the freezing point and anti-freezing. At the same time, antifreeze is also an essential antifreeze method. The amount of antifreeze must be appropriate. Care should be taken not to mix products of different brands and models. The second is engine oil. Winter has higher requirements for lubricating cars. If the engine oil is used in summer, it must be...

In winter, many friends have purchased exquisite plush car seat cushions for their cars to decorate their vehicles warmly and beautifully. In winter, the plush car seat is comfortable and warm, but it is also effortless to get dirty. After a period of use, the plush car seat is easy to get dusty, and at the same time, there will be different degrees of curling. Therefore, the plush car seat also needs careful care. To shine,  Here are a few straightforward ways to remove dust from a plush car seat in daily life. 1. Comb with a comb The quality of a wool car seat cushion is similar to that of animal hair. After a period of use, the hair will collapse. You can lightly comb the fur with a comb. Of course, it is more suitable for winter car seat cushions with long hair. Be careful not to use...

Car headlights are constructed of polycarbonate plastic, which makes the headlights more durable, but it also causes a potentially dangerous buildup of oxidation. When the sun shines on the headlight, it enlarges the pores of the polycarbonate plastic on the surface of the headlight, which accelerates oxidation and yellowing inside the headlight, allowing dirt and debris to adhere to the outer surface of the headlight. The following will teach you how to prevent the headlights from turning yellow and ensure the clarity of the headlights. 1. Wipe off the dirt, debris, debris, etc., on the surface of the headlight with a soft cloth. 2. Use soap and water to clean the headlights every three months to prevent the accumulation of dirt, etc., and prevent the headlights from turning yellow. 3. After cleaning, polish the headlights, wipe the headlights with a chemically synthesized polishing agent, and wax and maintain the headlights...

There is a lot of rain in spring, and the acidic substances in the rain will damage the paint of the car, so special attention should be paid to protecting the paint of the car. When carrying out seasonal maintenance, it is best to give the car a paint beauty treatment, which can not only prevent the paint surface from fading and aging but also show its fashionable and exquisite style. The air filter should be replaced on time The air filter of the car is equivalent to the human nose because the air in the spring contains more dust and fine particles Sand particles and air filters are easily blocked, causing the car to show symptoms such as weakness and unstable idling. Therefore, it is recommended to check the air filter once at 5000 kilometers in spring, which is good for the engine. Purified water cannot be added to...

Many car owners always have inappropriate misunderstandings when using their cars, and if the misunderstandings are not corrected in time, it is easy to damage the car. Here, some common misunderstandings are introduced for the reference of car owners. Using a large throttle is good for the engine Some car owners think that often using a large throttle is bad for the engine, but this is the wrong idea. Because the engine speed in gear is often mentioned above 4000, it is not only harmless but also has certain benefits for the engine. Often, it is not good for the engine to step on the accelerator in neutral or at high speed for a long time. It is not safe to habitually step on the clutch Many owners of manual motorcycles may habitually step on the clutch. This is the wrong approach. Because habitually stepping on the clutch is bad...
