As more and more people in the country purchase cars, gasoline and gasoline are gradually becoming more popular with the national V standard, resulting in a gradual increase in oil prices. The primary consideration for many consumers to buy a car is the cost of fuel. Some car owners have chosen diesel cars because their factory costs are relatively low. What are the differences between diesel and gasoline vehicles ? Today, Beimai.com will give you a detailed introduction.
1. Who is more fuel efficient
Gasoline car: â˜…â˜…â˜†
Diesel car: â˜…â˜…â˜…â˜…â˜†
Owners of diesel vehicles have said that diesel vehicles are very fuel-efficient, while gasoline vehicles are more fuel-efficient than diesel engines with the same displacement. The same level of diesel vehicles will save about 30% more fuel than gasoline vehicles.
Diesel vehicles are more fuel efficient than gasoline vehicles, which is determined by the technical characteristics of the engine. Because the compression-ignition diesel engine has a higher energy conversion ratio than the ignited gasoline engine, the energy consumption is 45%-60% of that of the gasoline engine.
Moreover, the thermal efficiency of diesel is higher than that of gasoline, and the calorific value of diesel is high. Therefore, the volume of combustion of the same mass releases more energy, and more work is done during the power stroke.
2. Who is better?
Gasoline car: â˜…â˜…â˜†
Diesel car: â˜…â˜…â˜…â˜†
The low-speed torque of the diesel engine is larger than that of the gasoline vehicle. When the displacement is the same, the diesel vehicle will feel the power of the diesel vehicle more powerful when it starts and climbs.
Compared with gasoline, diesel is less volatile, has higher power, and has a higher ignition point. Small diesel engines are one-third more fuel efficient than gasoline engines. The compression-ignition diesel engine has a higher energy conversion ratio than the ignited gasoline engine, and the energy consumption is 45%-60% of that of the gasoline engine.
3. Who is more convenient to refuel
Gasoline car: â˜…â˜…â˜…â˜…â˜…
Diesel car: â˜… â˜… â˜†
Although diesel vehicles have advantages in terms of power, fuel economy and economy, almost everyone will choose a gasoline truck when choosing a car.
Diesel vehicles are far less convenient than gasoline vehicles when refueling. Gasoline vehicles can be directly added to the corresponding oil according to the number required by the car, but diesel is not so easy. In the winter, when the temperature is too low, the owner must choose the corresponding negative diesel. Because of the slight carelessness, it is very likely that the diesel will freeze in the fuel tank and cannot start normally.
Of course, there is another reason, because the larger trucks such as domestic trucks use diesel fuel. Sometimes, when refueling, there may be queues with large trucks, and it may take a long time.
4. Who is less noisy?
Gasoline car: â˜…â˜…â˜…â˜…
Diesel car: â˜… â˜… â˜†
It is well known that the noise of diesel vehicles will be larger than that of gasoline vehicles, especially when the vehicle is accelerating.
Diesel vehicles mainly use compression ignition type ignition mode, while gasoline vehicles adopt ignition mode. When starting diesel vehicles, the compression ignition will be loud to a certain extent, so it can be clearly felt during driving. The noise of the diesel engine. In terms of noise, gasoline vehicles have certain advantages.
However, with the use of some advanced technologies, some diesel cars and SUVs use a more advanced fuel injection system, which also shortens the distance with gasoline vehicles in terms of noise control.
5. Who has a longer service life?
Gasoline car: â˜…â˜…â˜…
Diesel car: â˜…â˜…â˜…â˜…
Compared with the gasoline engine, the diesel engine has a simple structure and no ignition system, thereby reducing the probability of failure, and thus is more reliable than the gasoline engine, and the average service life is 1.5 times that of the gasoline engine. Moreover, the greenhouse gas emitted by diesel engines is also 45% lower than gasoline, and it is more environmentally friendly than gasoline engines.
Through the introduction of small series we feel good diesel or petrol car it good? Xiao Bian personally think like car because diesel in the country house belonging to a strategic reserve, when an emergency occurs, the use of diesel fuel will certainly be restricted to the time diesel vehicles It will not work properly. Therefore, it is more convenient to choose a gasoline car. I hope that today's introduction will help you. You can choose your car according to your own preferences.
