Is it really fuel efficient to use neutral gear?

Many car owners think that it is more fuel-efficient to use neutral gear. Today, let's talk about whether this statement is correct. Indeed, neutral glide will save fuel but that is only applicable to the past. It may not be applicable now. Why do you say so? Let Xiao Bian analyze it for you below.

First of all, the previous engine could not take its own oil, so it was necessary to mix the air and oil in an appropriate amount through the carburetor and feed it to the engine. Therefore, as long as the engine is started, it is necessary to feed oil through the carburetor, and the amount of oil intake depends entirely on the amount of air. The neutral gliding means that the engine is disconnected from the wheels when the vehicle is put on neutral. Therefore, the engine is quickly reduced to idle speed. At this time, the air intake volume is greatly reduced, so the oil intake is also reduced. In order to achieve what people say in the mouth of "fuel-efficient" effect. However, due to the large pollution and high energy consumption of carburetor engines, it has gradually been replaced by EFI engines.

At present, the fuel intake of our cars is generally intelligent and is controlled by computers on the cars. Therefore, when we release the accelerator car by coasting, the computer will automatically determine that the engine will be stopped. When the speed is reduced to near stop, the computer will automatically send fuel to the engine to achieve the effect of speed increase. Not only that, most of today's cars can always check the instantaneous fuel consumption, you can judge whether the taxi can be based on the instantaneous fuel consumption. So, even if you don't hang a neutral gear, the computer system will take the initiative to help you save fuel, and you don't need to coast through air to save fuel.

If we must hang a neutral gear to glide, then the result will only increase fuel consumption without saving fuel. Why? Because the connection between the engine, transmission and wheels is broken when the car is hung in neutral. Although the gliding distance will be relatively long, the computer would not dare to stop fueling the engine in order to prevent the engine from stalling. In spite of the fact that the gliding distance is short, the engine and the tire are connected, so the tire can drive the engine to rotate, which ensures that the engine speed will not turn off. Therefore, the engine can take a rest and it can be Achieve fuel-efficient results.

After reading the above analysis and introduction, will you also say that the car's neutral gliding will be more "fuel-efficient"?

Polyether Polyols for Flexible Foams

The products are suitable for preparation of flexible polyurethane foam plastics, such as furniture mat, mattresses and sound-absorbing board, carpet bottom, filters, packaging materials, etc. When foams are produced,the amount of the additives is variable and adjustable in a wide range.They also have good stability during foaming.
