The difference between gasoline and diesel cars

At present, the cars on the domestic market that use gasoline engines and diesel engines are roughly the same. Many friends who purchase cars will ask what are the differences between these two kinds of cars. Which kind of car will be better? In order to help everyone better understand the difference between petrol and diesel cars, follow Xiaobian to see what's different between the two.

汽油车和柴油车的区别

First, from the perspective of the cost of refueling. The cost of refueling a diesel vehicle is generally lower than that of a gasoline vehicle. In the past, we always believed that the quality of diesel was relatively poor and the price was low, but now the diesel oil has been greatly improved. The cost of refueling a diesel car is even lower, and the performance of a diesel engine is also increasing. In the future, diesel-powered cars will become more popular. The price of domestic gasoline has been rising all the way. After experiencing price cuts, it has now risen again. In fact, petrol vehicles consume more fuel than diesel vehicles. From the point of view of the burning efficiency, even if a diesel vehicle does not refuel at a certain speed, it can maintain a certain speed, while petrol vehicles cannot.

Second, from the point of view of the ride and driving experience. In this respect, diesel vehicles are slightly inferior because of the high carbon content of diesel fuel and the presence of certain impurities. Therefore, after the launch, the automobile exhaust often emits black smoke, and the sound of the engine is very large, giving a noticeable The sense of trembling, ride experience is not very good. Gasoline vehicles are much better in this respect. During the driving process, gasoline can be fully burned, the driving process is smooth, and the sound produced by the engine can hardly be heard. The ride experience is generally very good.

Third, from the perspective of the impact on the environment. The extraction of diesel fuel is rougher than that of gasoline. The combustion efficiency of diesel engines is also not as high as the combustion efficiency of gasoline engines. Therefore, the exhaust gas after diesel combustion contains more greenhouse gases, which has a greater impact on the atmospheric environment. The gasoline engine combustion efficiency is relatively good, the greenhouse gas after combustion of gasoline is mainly carbon dioxide and nitrogen-containing gas, relatively speaking, the impact of gasoline vehicles on the atmosphere is smaller.


Deep Groove Ball Bearing

Deep groove ball bearings are bearing the most widely used type. The basic model consists of a deep groove ball bearing outer ring, an inner ring, a Steel Ball and a group of holding structure into. Deep groove ball bearing type has two kinds of single and double row deep groove ball structure also split seal and open two structures, it means open bearings without sealing structure, sealing deep groove ball into dust seal and oil seal. Dust Gland Material steel stamping, serve only as a simple prevent dust from entering the bearing raceways. Oil-proof seal for the contact, which can effectively prevent the bearing grease inside the spill.
