There are two types of cars currently on the market: a diesel car, a petrol car, and the simple point is that one needs to add gasoline, and the other is to add diesel. Which is better than that, diesel is cheaper than gasoline, and diesel is more fuel-efficient. The following specific analysis.
First of all, what kind of fuel-efficient? For the car owner, of course, what kind of concern is more cost-effective, after all, the car is a means of transportation. Most people know that running the same number of kilometers, diesel cars can save 30% of the oil than gasoline cars. Because the thermal efficiency of diesel is higher than that of gasoline, the energy conversion ratio of the compression ignition type diesel engine is higher than that of the ignition type gasoline engine.
In terms of power, for example, the two cars with the same displacement can clearly feel that the power of diesel cars is much stronger than that of gasoline vehicles when climbing. Diesel fuel is characterized by low volatility, high power, and high ignition temperatures. Therefore, small diesel engines are more than 30% more economical than gasoline engines.
In terms of noise, of course, diesel has so many economical and practical features. It has some disadvantages. That is, the noise is relatively large. We can clearly feel the noise of the engine during the driving process. Gasoline vehicles in this area have a relatively large advantage.
When refueling, diesel vehicles are far less convenient than gasoline vehicles. Gasoline vehicles are added to the corresponding gasoline according to the requirements of the car. In winter, when the temperature of the diesel car is lowered, the owner of the car is slightly careless, causing the diesel fuel tank to freeze. Can't start the car anymore. And many carts that pull goods are diesel cars, so you may have to wait in line when you are refueling.
As far as the service life of the car is concerned, the construction of the diesel car is simple, there is no point system, so it is not easy to malfunction, and it is relatively reliable than the gasoline car.
In terms of environmental protection, diesel vehicles emit less pollutants than gasoline vehicles, and emit lower emissions and are more environmentally friendly than petrol vehicles. However, the current choice of gasoline vehicles is much more than that of diesel vehicles.
