For many people, a car is still a "luxury", and a new car bought with hard-earned money will have to be driven for at least 10 years. Whether the car is durable and less faulty has a lot to do with the operation during the "run-in period". Generally speaking, before the new car has a mileage of 5,000 kilometers, it belongs to the running-in period. Although the engine of the new car has undergone "cold running-in" before leaving the factory, this running-in cannot replace the running-in in actual use. So, what problems should you pay attention to when running in a new car? You might as well learn the ten new running-in skills we will introduce, so that your car can go through this running-in period that determines "future happiness". Tips 1: It is necessary to warm up the car when it is coldSome people will ask: the engine technology...

Turbo is referred to as Turbo. If you see Turbo or T at the rear of the car, it means that the engine used in the car is a turbocharged engine. I believe that everyone has seen many such models on the road, such as Audi A6 1.8T, Passat 1.8T, Bora 1.8T and so on. A turbocharger is actually an air compressor that increases intake air by compressing air. It uses the inertial momentum of the exhaust gas discharged from the engine to push the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipeline to pressurize it into the cylinder. When the engine speed increases, the exhaust gas discharge speed and the speed of the wheel also increase synchronously, and the impeller compresses more air into the cylinder. The increase in the pressure and density of the...

Car anti-theft is the most concerned issue of every car owner. At present, there are many kinds of car anti-theft devices, but they can be summed up in three forms: gear locks, car network anti-theft devices, electronic Immobilizer. Shift lockShift lock has a variety of advantages, using the most primitive anti-theft principle to mechanically prevent thieves without destroying The original car line, does not increase the battery load, easy to use. The unique lock channel design of the soft chain shift lock improves the reliability of theft prevention to a higher level. Different from the ordinary in-line lock cylinder, the lock channel of the soft chain lock is a curved soft design, which will not leave any gap for the external forced theft tool. Its key is soft like our metal strap, usually shrinks in the sheath, pushes it into the curved lock channel when needed, and turns it against...

What method should car owners use to identify the difference between new tires and retreaded tires? The most common is to observe the color and gloss of the tires. The color and gloss of the retreaded tires are relatively dull. It can also be identified by observing the overlap between the tread and the sidewall. The overlap between the tread and the sidewall of a retreaded tire is not as smooth and smooth as a new tire. Professional masters identify tires by the signs on the tires. There are some raised signs on the tires, indicating the model and performance of the tires. These are the breakthrough points for identifying retreaded tires. Generally, retreading The signs of the used tires are re-applied after retreading, while the signs of brand-new tires are integrated with the tire. The identification method is to scratch these signs with fingernails. Generally, these signs of retreaded...

Chinese people often associate the luxury of a car with the interior space. Therefore, ample interior space has become an indispensable factor in considering whether a mid-size car can meet the more needs of private users. Nowadays, when many consumers buy a car, they only judge the interior space of the car from the appearance of the car. This is not comprehensive, the wheelbase, the rational design of the center console and the layout of the engine compartment are all important factors that affect the interior space of the car. The so-called wheelbase is through the midpoint of the two adjacent wheels on the same side of the vehicle, and is perpendicular to the longitudinal symmetry of the vehicle The distance between the two perpendiculars of the plane. Simply put, it is the distance from the center of the front axle to the center of the rear axle. The wheelbase...

Many car owners have had trouble starting their cars. Especially for old models, it is very likely that it will not catch fire after starting many times. At this time, some "novices" will inevitably wonder: Is there something wrong with the car? In this regard, experts explained that the reasons for the difficulty of starting the vehicle are many. If you encounter such problems, you can find the reasons from the following points: < STRONG>Reason 1: The fuel injector is dirtyAfter the vehicle has been running for a period of time, it is easy to stick some glue on the fuel injector, which will block the normal fuel injection amount , resulting in poor gasoline atomization, so that the ignition delay, the car is difficult to start the phenomenon. Support: Go to the auto repair shop to clean the fuel injector. Cause 2: The battery loses powerThe battery has a...

The cold winter has officially arrived. Our car should also pay attention to the maintenance after entering the winter. Special care for the battery is quite necessary. Here's a DIY method for battery maintenance. The battery is most afraid of low temperature, and the battery capacity in low temperature environment is much lower than that at normal temperature. Therefore, the electrolyte level should be checked before the cold season. If necessary, the electrolyte of the battery should be supplemented, the specific gravity of the electrolyte should be adjusted, and the storage status should be checked, and charged if necessary. Appropriate use also requires careful maintenance. The maintenance of the battery is actually not complicated. You can do it yourself. Hands-on practiceStep 1: Wipe the outside of the battery with a damp cloth to remove dust, oil, white powder, etc. Wipe up the leaking dirt. Scrub the stigma of the battery...

The service life of an automobile battery is not only determined by the structure and quality of the battery, but also closely related to its operation and maintenance. Generally, the service life of a car battery is about 2 years, and if properly maintained, it can reach 3 to 4 years. At present, there are still many misunderstandings in the maintenance of the battery, which leads to the early damage of the battery. Misunderstanding 1: When using maintenance-free batteries, simply think that maintenance-free means that no maintenance is required. Misunderstanding 2: Corrosion on the surface of the battery pole post does not need to be dealt with, as long as it is not loose. Corrosion appears on the surface, and corrosion occurs on the inner surface of the terminal, resulting in an increase in the resistance value, affecting the normal charging and discharging of the battery, and must be dealt...

During the working process of the engine, the performance of lubricating oil is constantly declining. If it is not replaced in time, it will cause damage to the engine. Therefore, we should master some simple methods to identify the deterioration of lubricating oil. Oil Flow Observation MethodTake two measuring cups, one containing the lubricating oil to be checked, and the other empty on the table. Lift the measuring cup full of lubricating oil 30-40 cm away from the table top and tilt it, let the lubricating oil slowly flow into the empty cup, and observe its flow. If the oil flow is suddenly fast and slow, and sometimes large pieces flow down, it means that the lubricating oil has deteriorated. Hand twisting methodTwist the lubricating oil between the thumb and index finger for repeated grinding. There are few chips and no friction. If you feel a large friction such as...

After the car body is collided, the body steel plate is wrinkled, and the paint surface is easily damaged. The steel plate is exposed and easy to rust. It must be repaired and repainted immediately. Unlike metal, the paint layer has a very low hardness and is easily damaged. Therefore, you must use a soft suede, cotton or wool brush when cleaning or sanding, otherwise, scratches will be scratched and self-defeating. After the car has been used for a long time, the paint will inevitably fade, whiten, and darken more or less. Generally, frequent cleaning can reduce the phenomenon of fading; mild fading can be waxed and polished, and moderate fading can be waxed and polished. It needs to be ground, and if it is serious, it can only be repainted. Nowadays, many people like metallic paint, but they need more care for metallic paint, often polishing and waxing. High-efficiency...
