Nowadays, the use of diesel vehicles is prevalent in large passenger cars and trucks, and the use of gasoline vehicles dominates in domestic cars. Each of them holds one side. What is puzzling is why diesel vehicles and petrol vehicles will Is there such a clear watershed? Is that better than a diesel car or a petrol car? Then we may objectively compare the strengths and weaknesses of each other for discussion and discussion.
Diesel vehicles
Advantage:
1. Low-speed and high-torque means that at a very low speed, the highest torque can be obtained, and the explosive force is strong. This is also the biggest difference from the petrol car, which shows that it is not possible to grind the road or climb the slopes on complex roads. Strong load capacity.
2. Fuel-efficient and economical, the energy consumption is only 45% to 60% of the gasoline engine; not only that, compared with the gasoline engine, the complicated high-pressure ignition device is less complex, the service life is mostly longer than that of the gasoline engine, and the maintenance cost is also saved. pen;
3. The ignition point is higher than gasoline, so the safety factor is high. It will not be ignited due to prolonged high-temperature heating or other sudden conditions, causing an explosion.
4. Less exhaust emissions, more environmentally friendly than petrol vehicles. According to statistics, the greenhouse effect of diesel engine emissions is 45% lower than that of gasoline, and carbon monoxide and hydrocarbon emissions are also lower than gasoline vehicles.
Disadvantages:
1. A lot of noise is emitted at the start-up, and the first-time test cars are mainly psychologically prepared. Not only are there great sounds, but the body will also vibrate strongly;
2. It is relatively troublesome for diesel vehicles to start in the winter, because the properties of diesel oil will condense into wax in winter, so you need to warm up in advance.
3. The price of diesel vehicles is high. Although the diesel used in diesel vehicles is not expensive, the technical requirements for the production of diesel vehicles are high, resulting in diesel cars ranging from 1 to 3W higher than the price of gasoline vehicles.
Gasoline car
Advantage
1. The petrol car has a large power. Although it is not as explosive as the large torque of the diesel car, the win is stable and the average speed is faster than that of a diesel car.
2. The start-up noise is small and much quieter than diesel cars;
3. The price of petrol cars is relatively affordable compared to diesel cars.
4. Whether it is a hot start or a cold start, it will not be affected by seasonal weather;
5. The lighter body is relatively simple and easier to operate than a diesel vehicle.
Disadvantage
6. The amount of oil consumed is large. In general, one level of gasoline vehicle is about 25-30% of that of diesel vehicle.
7. The amount of carbon monoxide emitted seriously pollutes the environment and is not environmentally friendly.
8. Gasoline itself is volatile, so the odor is great, and car owners with motion sickness must pay special attention to it.
Xiao Bianji: Actually, I think it is a matter of opinion whether the diesel vehicles are good or the gasoline vehicles are good. What's more, the future is the mainstream of diesel or gasoline cars. In fact, it is not the most important thing for us. The most important thing is that the owner can choose a car that suits his needs.
