买车需知

买车需知 Buy a car need to know The heavier the car, the more fuel it will consume From the point of view of saving, vehicle weight and fuel consumption is proportional to the weight of the larger, more fuel-efficient car, the use of relatively poor economy, such as the small vehicle weight increases 40 kilograms to fuel consumption of 1%; but the advantages of better stability since the major automobile has a sharp turn and brake condition, is not easy to happen "floating phenomenon. Two, different drive mode 1, off-road vehicle front and rear wheel drive, traction, through strong adhesion, good stability, the body and the transmission system of plate thickness, the safety coefficient is higher than the sedan, but for off-road weight, poor fuel economy. 2, senior car front and rear axle bearing load is basically the same, strong power, traction, driving in climbing, muddy roads and bumpy road, power, prevent rear wheel sideslip and stability is obviously superior to the "front drive car. The drive shaft returns to the rear axle, causing the floor to bulge, a few total components are arranged, occupying a larger space, and it is difficult to make the car smaller. 3, the small and medium-sized car saves the transmission shaft, the transmission system is compact, the weight is lightened, the floor reduces and is flat, the center of gravity drops. When uphill, the weight is shifted backward, the front axle load is reduced, and insufficient traction can not be generated. It is difficult to use in the mountainous area where the upper and lower slopes are more. 4, the micro car saves the transmission shaft, adhesion, traction, but the wheelbase is smaller, there is no exhaust pipe under the floor, engine exhaust, noise will not pollute the car. Rear axle load, turn easy sideslip, long and complex control system, cooling system complex, suitcase is too small. Three, automatic car save trouble, do not save money Automatic gear (also called stepless speed change) is equipped with automatic control device. It can automatically adjust the gear according to the speed of the vehicle. Without manual operation, it saves a lot of shift and clutch work. The disadvantage is that the price is expensive, the cost of the maintenance is very high, and it is used more than the manual gear fare. Because the power transmission of the automatic transmission is done by hydraulic pressure, it will cause power loss in the work, especially in low speed or traffic jams. When stop and go, it will increase fuel consumption. Four, the aluminum ring for car wheel At present, the price of aluminum alloy wheel rim is about 2~3 times of that of steel wheel, but the benefit is much higher than that of steel wheel: 1, light quality, fuel-efficient. 2, good heat dissipation, increase tire life. 3, high roundness, can improve wheel movement accuracy, suitable for high speed driving. 4, good elasticity, improve vehicle ride comfort, easier to absorb vibration and noise in motion 5, can be recycled 100%, belong to environmental protection products. Five. Buy a zero kilometer car The "zero kilometer" car means that the vehicle is sold directly without any operation, or transported to the seller's hands by a special transport vehicle, and its mileage is zero. When buying, do not choose a new car that has traveled a certain distance (although the mileage is the vehicle mileage). Because car drivers often violate the provisions to run in period car driving, hurry and speeding, running caused by bad, even the engine early wear, buy this car will be no end of trouble for the future. Six, buy domestic cars or imported cars? Imported cars are superior to domestic ones in quality, But from the comprehensive advantages and disadvantages in terms of analysis, in addition to price performance in front of the other, in the days after the repair cost and spare parts supply, import car does not take any advantage. Domestic car repair more outlets, and relatively cheap charges. Imported vehicles once malfunction or accident, repair is relatively trouble, is a performance, the structure changes of imported cars faster, some repair technology is not comprehensive, it is difficult to provide high quality services; two is imported accessories are not only expensive, but also there are a lot of fake products. Therefore, no matter from the economic or practical and convenient considerations, we should try to choose domestic brand-name cars. Seven, the purchase of small cars imported, how to choose? With the development of national economy and the improvement of people's living standard, the people demand for cars is more and more big, the quality of the car is more and more high, small cars imported relatively complete types, for passenger cars, for passenger and cargo carrying some vans and cars and other tools. When buying small cars, choose the full range of vehicles for use. 1, the choice of car weight: the same type of imported cars have a technical index is self-respect, generally low self-respect economy will be better. According to the determination of small car weight, each increase of 40 kilograms, to consume more than 1% of the fuel. Especially when selecting passenger cars, we should pay attention to the selection according to the actual situation of our country. The quality of lubricating oil, fuel oil and road conditions in our country are still can not adapt to the high degree of luxury, standby power and heavy vehicles, if you just use this type of car, will cause waste or shorten the service life of the vehicle in use. 2, engine type selection: imported small car engines, gasoline and diesel engines two kinds, in other conditions the same, diesel engine car economy is good. In the same type of vehicle, the smaller the engine displacement, the better the economy. According to China's road conditions, the car with a displacement of 1500 ~ 2200 ml of engine, 9 ~ 12 seat Tourer with 1800 ~ 2200 ml of engine, 0.5 tons of vans with 2000 ~ 2500 ml of engine, 1.50 ~ 1.75 ton van engine should use 3000 ml. 3, maintenance convenience, choice: should choose parts of security, convenient maintenance vehicle, which can reduce maintenance costs and reduce stop time. At present, the Japanese imported cars, TOYOTA auto parts types and prices are better than other models. Automatic transmission in our country on the road using poor economy, maintenance difficult, should try not to choose. 4, good elasticity, improve vehicle ride comfort, easier to absorb vibration and noise in motion 5, the body style choice: body style generally according to its use and hobby choice, according to the economic angle of choice, body smaller, economic better.
