What are the volumes of the engine and how do they differ?
The motor is the heart of every car.Its main characteristics are power, which is measured in horsepower (hp), and the volume, measured in liters or cubic centimeters. There is an opinion that the higher the last figure, the better the machine. We can agree with this, but only in part. It all depends on what the purpose of the operation of the car is pursued. Powerful aggregates have both their pluses and their disadvantages. Small engine volumes are quite viable and enjoy a certain popularity among all segments of the population.
Classification of cars by volume of the engine
At once it is necessary to understand how thisvalue. Each "engine" consists of a certain number of cylinders. The total index of their internal size determines this most important characteristic for the part. It is important that diesel and gasoline cars have different classification. If to speak about the last, it is accepted to allocate: minicars (to 1,1 l), midget cars (from 1,2 to 1,7 l), mid-size cars (from 1,8 to 3,5 l) and large-size cars (over 3,5 l). Also, the volume of the engine depends on the class of cars - the higher it is, the stronger the motor. This directly affects the speed and fuel consumption. Obviously, a more bulky mechanism will allow to accelerate rather quickly, and midget cars are not designed for racing. But we should pay tribute to modern models, which also show convincing figures on the speedometer and with small "engines".
How does the car's engine volume affect fuel consumption?
Many will immediately reply that it is directly proportional.And they will be right. It is known that powerful machines consume more. But here on the road there is a reverse effect - they are a bit more economical. This difference is not felt due to the fact that in the conditions of the city everything is exactly the opposite.
But do not think that power depends onlyfrom one of this indicator. Important and torque, and transmission gear ratios. Sometimes it happens that a weak motor, which pulls well at the "bottoms", is much better than a more voluminous fellow, but with a bad draft.
It is generally accepted that the volume of the diesel enginecar must be necessarily large. But modern models go well and on 1,1-liter babies without problems, and in motorcycles even install motors on 0,6 l.
How does the price of the car depend on the volume of the engine?
It's no secret that more powerful unitsexpensive. This is due to the fact that engine volumes of more than 2.5 liters are used for high-class machines that require other expensive mechanisms in the assembly. Someone can say that you will have to spend not only when buying, but also during operation for fuel. But for the comfort of coming to always pay?
One more common opinion is that large volumesengine provide him a long service. This is far from the case. After all, the operating time of this part depends not on the size, but on the quality of the fuel, used in the course of its operation, careful care and the conditions in which the car is located.
When choosing a car you need to think carefully,which is the engine volume is optimal. It is not necessary to pursue prestige and overpay for extra cubic centimeters. It is best to treat the car simply as a means of transportation.
