What is the relationship between the number of cylinders in an automobile engine and the engine speed? The power of the car mainly depends on the engine. Engine is the source of automobile power and the heart of automobile. If the engine wants the car to run, it needs the cylinder inside the engine to do work and generate electricity. The engine doesn't have a cylinder, and many cylinders are working. The engine we usually say refers to the number of cylinders in an automobile engine. Generally speaking, the more cylinders, the higher the rotating speed and the greater the rising power.

The common cylinder numbers of automobile engines are 3, 4, 5, 6, 8, 10, 12 and 16. The engine with the displacement below 1 liter has 3 cylinders, the engine with 1-2.5 liter has 4 cylinders, and the engine with about 3 liters has 4 cylinders. Under the same displacement, the more cylinders, the smaller the cylinder diameter, the higher the speed and the greater the rising power. Generally, there are in-line cylinders, V-type cylinders and W-type cylinders. Generally, engines below 4 cylinders are arranged in line, engines above 6 cylinders are arranged in V-shape, and engines above 12 cylinders are arranged in W-shape.

The cylinder is the power source of the car. Gasoline and diesel are burned in the cylinder, and the expanding gas drives the related machines to move, which is converted into the power to push the car forward. More cylinders produce more energy and powerful thrust. How many cylinders does an engine have? The sum of the working volumes of all cylinders is called engine displacement, which is generally expressed in liters (L? It is said that the "power" of large displacement is good, so off-road vehicles usually have more cylinders, and the 4-cylinder engine with the largest displacement is relatively stable. The 3-cylinder engine locomotive is suitable for cities, with sufficient power, small displacement, light weight, low fuel consumption and relatively low maintenance cost, but its absolute power is small, the power is slightly insufficient when driving at high speed, and the vibration jitter is slightly large. With the development of technology, the more cylinders, the more emissions, the higher the power and, of course, the greater the price difference under the same cylinder diameter. For example, cars with 4-cylinder and 6-cylinder engines may have a price difference of 10,000 yuan even if they emit 2 liters.

Is the more cylinders, the better the fuel consumption? Theoretically, the more cylinders, the heavier the car body and the higher the fuel consumption. However, according to the specific situation of the vehicle, the cylinder diameter and the engine stroke determine the displacement. The fewer cylinders, the larger the cylinder diameter and the higher the fuel consumption. For example, if the same four cylinders are discharged, the larger the cylinder diameter is. If the fuel consumption is the same, under the same displacement of four cylinders, multiple cylinders will indeed bring more flatness. However, if the discharge exceeds a certain threshold (i.e., too large or too large)

With small displacement and multiple cylinders, the air intake is less, but with too many cylinders, the air that can be distributed by each cylinder becomes smaller. With less air, no matter how much gasoline is blown, gasoline will burn with less air. This is the disadvantage of small displacement multi-cylinder engine. At the same speed, the torque will increase, and the acceleration of the car will get worse, in order to prevent it.

Which cylinders should I choose to buy a car? However, for city agents of family cars, the fewer cylinders, the better. If there are three cylinders, there is no need for four cylinders. If there is a turbine, you can't pump it yourself. This can save the cost of the car. In addition, you won't lose too much power experience. If you choose sports cars and off-road vehicles, the more cylinders, the greater the power. In short, the situation that meets your actual needs is the right choice!
