There are two main models on the market today. One is, and the other is diesel. Many people who are not very familiar with the car do not know the difference between gasoline and diesel, so they do not know how to choose when buying a vehicle. What is the difference between a gasoline car and a diesel car?
Diesel vehicles emit less carbon dioxide than gasoline vehicles, but diesel vehicles emit four times more nitrogen oxides and 22 times more particulate pollutants during driving. These substances can seriously damage people's bodies. Organs that cause lung or cardiovascular disease, internal organs and other diseases can even lead to heart disease, stroke, and diabetes. Therefore, environmental pollution caused by gasoline and diesel vehicles is differently ignored.
From the aspect of power, the low-speed torque of diesel vehicles is larger than that of gasoline vehicles. Under the same displacement, diesel vehicles are significantly more powerful than petrol vehicles when they start and climb, but diesel is less volatile than gasoline. Compared with the power, the ignition point is also relatively high. Therefore, in the case of the same model, the diesel fuel consumption is one third higher than that of the gasoline engine.
Compared with gasoline vehicles, diesel cars have lower CO2, CO, and HC emissions, but NOx and particulates are high. Through continuous technological improvements, the CO2 emissions of diesel vehicles are now reduced by about 25 percent. NOx and particulate emissions are also reduced by more than 98% compared to older diesel vehicles. However, diesel vehicles can only fully utilize the energy-saving and emission-reduction effects by using clean diesel fuel. The poor quality of diesel fuel will greatly increase environmental pollution.
Although there are many advantages of diesel fuel, it is still mainly gasoline vehicles. The main reason is that there is insufficient supply of diesel fuel and there is no way to meet the current market demand. At the same time, many diesel oil products on the market are very poor and will cause serious problems during use. With the diesel pollution, many consumers are still impressed by the noise and emission of black smoke. Therefore, they are reluctant to use diesel vehicles.
