Are there more diesel cars in developed countries?

Yes, there are many more diesel cars used abroad than at home.

Compared with gasoline engines, diesel engines have the characteristics of high efficiency, low fuel consumption, long life, and reliable use, and at the same time, diesel vehicles have one-third higher fuel economy than gasoline vehicles. In developed countries such as Europe and the United States, there are not only non-discriminatory policies for diesel vehicles, but also the process of diesel is extremely fast. In the more mature European and American automobile markets, more than 90% of commercial vehicles are powered by diesel; The proportion of diesel cars has approached 40%; Passenger cars with diesel engines accounted for 35 percent of total sales, while France accounted for 54 percent; In Germany, almost all taxis use diesel engines; In Japan, where the industry started late, the proportion of diesel engines in commercial vehicles also exceeds 38%.

It is understood that in the European market, a large part of the reason for the popularity of diesel cars is the problem of concept. In the eyes of the French and Germans, a person who buys a diesel car means: this person is a person who loves environmental protection, is a person with relatively high quality, and is a person with noble character and worthy of respect.

In these developed countries, driving a fuel-efficient car is a real fashion. In today's increasingly tight energy situation, China is gradually aware of the advantages of diesel power, gradually connecting with the world, and encouraging the development of diesel-powered vehicles.

Diesel cars are popular in Europe, why can't they be done in China, do you know the reasons behind it?

Each has its own advantages, and the decibels are as follows:

First, the advantages of gasoline vehicles.

1. The sound is small.

At this stage, no matter how diesel vehicles are made, the movement of gasoline vehicles is still smaller than that of diesel vehicles.

2. High power.

Disadvantages of gasoline cars.

1. High fuel consumption.

Usually, a grade of gasoline vehicles is about 25-30% more waste oil than diesel vehicles.

2. Small torque.

The torque of gasoline vehicles is generally 30%-40% less than that of diesel vehicles. Climbing hills, overtaking and planing, torque is the most important.

Second, the advantages of diesel vehicles.

1. Long life, economical and durable.

Diesel engine.

The speed is lower, the related parts are not easy to age, and the parts wear is also more than that of gasoline engines.

Less, the life is also relatively long, there is no ignition system, and there are few auxiliary electrical appliances, so the failure rate of the diesel engine is much lower than that of the gasoline engine, which has low fuel consumption and liters of electronically controlled common rail turbocharging.

The fuel consumption of a diesel engine is comparable to that of a liter of electronically controlled gasoline engine.

2. Low speed is large.

Torque diesel engines can usually obtain high torque at very small speeds, which is better than gasoline engines in complex road surfaces, climbing, and loading. However, it is not as good as gasoline vehicles in terms of speeding up and high-speed driving on the highway.

3. High security.

Compared with gasoline, it is not volatile and ignition point.

It is higher and less likely to be ignited or occur by accident**, so it is more stable and safe to use diesel than gasoline.

4. More environmentally friendly.

The greenhouse effect from diesel engine emissions.

45% lower than gasoline, carbon monoxide.

With hydrocarbon emissions are also low, just nitrogen oxides during the service life of the vehicle.

and PM (particulate) emissions are greater than those of gasoline engines. With the continuous progress of technology, its emissions have reached Euro III and Euro IV emission standards.

Diesel engine disadvantages.

1. Loud noise.

Vibrations affect driving comfort, so passenger cars are relatively rarely used. However, with the continuous progress of technology, some mid-to-high-end diesel vehicles have been quite close to gasoline engines, and major domestic and foreign automobile manufacturers have also launched many diesel cars and SUVs.

2. High manufacturing cost.

The fuel injection device of diesel engine is extremely precise and difficult to manufacture, and if inferior fuel is used, the life of the injection device will be seriously shortened. Due to the compression ratio of diesel engines.

It is very high, and it requires high structural strength, so the weight and volume will be relatively large.

3. Difficult to start.

Due to the fact that diesel is not volatile and compression ignition, etc., it starts coldly in winter.

Not as good as a gasoline engine. Even if there is a preheating device, it should be preheated for tens of seconds before it can be started.

It doesn't matter if it's a diesel car or a gasoline car, all. It's just that there are different types of diesel and gasoline vehicles. Diesel car power, suitable for pulling goods or pulling. Gasoline cars are mainly pulled.

It must be a gasoline car good. Because gasoline vehicles have a more obvious sense of acceleration than diesel cars, and it is also more convenient. So gasoline cars are good.

Diesel cars have the benefits of diesel cars, gasoline cars have the benefits of gasoline cars, relatively speaking, diesel cars are much more powerful than gasoline cars, but diesel cars are more expensive than gasoline, and diesel cars are more expensive than gasoline cars.

Personally, I think gasoline cars are better, because gasoline cars have better power, the driving environment will be more comfortable and quiet, and the driving experience will be better.

No matter how good it is, it will not be installed in a passenger car...

Why don't there be diesel cars in China? A friend told me that he wanted to buy a diesel car, I think his idea is really good, let's say that diesel cars are powerful and fuel-efficient, so why are there so few people driving on the road? Before explaining this problem, it is necessary to popularize the knowledge of diesel cars.

First of all, we must know that the structure of diesel engine and gasoline engine is different, diesel engine is not spark plug, it is not burned by ignition, but by using a pressing way to make diesel combustion, so that the most intuitive advantage is that the structure is simple and the compression ratio is high, and the compression ratio is high, and the two advantages of strong power and fuel saving are highlighted.

Diesel cars have so many advantages, why are they not common in China?

The first point is that the oil of diesel fuel is easy to cause fuel injector blockage, compared to foreign countries is relatively easy to happen, the direct reaction is to feel that the car can not supply oil, and there is that diesel car refueling is not so convenient, after all, at the gas station and you are basically refueling with large trucks, even if they are not filled every time only add a few hundred liters of diesel fuel is enough for you to wait.

The second point is the diesel label, the diesel label represents its solidification temperature, the diesel and gasoline are not the same, although there are anticoagulants and other such products, but can not make the oil solidify when the sheep is killed, but if you really add the wrong oil, we will be very embarrassed the next morning.

The third point is noise and vibration. Compared with gasoline engines, diesel engines produce more impact than gasoline engines, so the noise and jitter will be greater.

Although the noise and vibration of our diesel cars have been greatly reduced, they still cannot be compared with cars of the same level in quiet and stable diesel cars.

The fourth point is the policy, in some big cities such as Beijing, it is a well-known fact that diesel passenger cars cannot be licensed at all, and even the diesel version of Range Rover, Discovery and other luxury cars have not been spared.

Because the cost performance of diesel cars is very low, and now there are many provincial and municipal regulations: diesel cars are not allowed to enter the city, so there are very few people who buy them, and slowly no manufacturers are willing to make diesel cars.

On the one hand, because the technical requirements are relatively high, China has not been able to meet the technical requirements, and the safety factor is not very high. On the one hand, fuel vehicles are already entrenched, and people are reluctant to make changes.

Because diesel cars are not competitive, plus the pollution is very serious. Therefore, there are no diesel cars in China.

For domestic diesel models, as long as there are the following reasons:

1.Restrictions of national policies, such as Beijing, individuals who buy diesel passenger cars are not given a license plate 2The ratio of gasoline to diesel in petroleum smelting tends to be a fixed proportion, and diesel is used too much and the amount is too large, resulting in a shortage of diesel.

3.Diesel is an important material for our country's national economy, and diesel fuel for passenger cars is not very sufficient.

The quality of domestic diesel is too poor! **Not supported!
