What is better diesel or gasoline?

Choosing a car is also a choice of fuel. Everyone knows that diesel fuel is much cheaper, but is it really better than gasoline. Let's get this straight. So:

What's better? Diesel or petrol?

What is the difference between the principles of operation of diesel and gasoline engines? The whole difference lies in the method of ignition of fuel in the engine. Gasoline burns with spark plugs and its interaction with the air. The diesel burns due to the preheated air until the moment of explosion, that is, without spark plugs. Details and components of diesel engines are much stronger than its gasoline counterparts, since the load that they have as a result of the reaction greatly affects the design of the engine. This influence is devastating. If we talk about the price, it should be noted that the fuel pump and injectors in a diesel engine are much more expensive than in a gasoline engine. The advantage of a diesel engine in the ignition system is the absence of complex electronic systems to start the reaction.In a gasoline engine can not do without them. Well, do not forget about the efficiency of a diesel engine. This has already been said above. Gasoline is more expensive than diesel. Accordingly, a diesel car will travel longer, while spending less fuel than a gasoline car.

What is better? Diesel or petrol? If we are talking about the Russian conditions of car operation, then it is worth noting that in winter, diesel fuel thickens. The car simply can not start and work on this fuel. However, there are special types of diesel. For winter and for summer. Unfortunately, their quality in the Russian markets leaves much to be desired.

Until recently, diesel scolded for the fact that it affects many parameters of the car. High vibration levels during operation, smoky exhaust and low performance. These are not all cons for which diesel cars were criticized. However, in recent years, technological progress has eliminated many of the shortcomings of diesel. The problem of low power is now solved with the help of turbocharging, for example. And this is not the only acquisition.

In general, buying a new car with a diesel engine seems to be more promising. If we are talking about buying a used car, then there is not much difference. It is necessary to understand each used car separately. Since a large number of factors affect its quality work. Accordingly, it is better to buy a new car with a diesel engine, and the old one with a gasoline one.
