Today I will tell you about some reasons for the automotive fuel consumption and how to reduce fuel consumption。Many friends think that automatic transmission cars are greater than the fuel consumption of the hand gear，Let's discuss this issue today。

Anyone who has drove a manual blocking car knows。When driving a manual transmission car，When the road conditions are not good, the file must be reduced。The momentum of the engine →→Mechanical energy.The efficiency is 100%after the clutch is completely combined.

So the automatic transmission vehicle is the automatic lifting of the file，Its energy conversion isEngine motor energy→→liquid energy→→kinetic energy,Efficiency is about 80%first，But the speed reaches a certain time，The torque converter of the liquid force will be locked equal to the mechanical transmission efficiency of 100%。How did it raise the gear by itself? First of all, according toThe opening of the throttle(Reacting the load of the engine)，Also based on the carMotors.For example, the car now is 30km/h，The opening of the throttle has reached 40%，That indicates that the car is driving at a low speed，The load of the engine is relatively large。At this time the gearbox will be reduced，Converse。

Let the automatic transmission rise faster

If the car is drove, it will save the transmission as soon as possible，This transmission ratio will be smaller，The efficiency will be higher。According to our understanding, I step on the big accelerator when I start.，Let the car run quickly，I feel that this will save fuel。Actually doing it like this is wrong。Auto -transmission cars usually step on the accelerator when starting，The speed of the car should be a little bit up, and then the throttle pedal should be easily stepped and then stepped on。This way, a transmission will rise immediately after a transmission，Because you operate the control unit of the transmission in this way, the small load of the signal of the throttle pedal is received，It will rise in a block，Efficiency will increase。

Can't drive too fast in the speed

The speed of the car will seabet appbecome larger when the speed is slow，But it does not mean that the faster the speed is, the more fuel it will be。If the car is too slow, the efficiency will be too low，The faster the opening of the wind, the larger the wind will be larger。Our economic speed is to raise the transmission to the highest gear and step on the throttle pedal to step into about three -fifths。The speed of the car is about 80 ～ 100，This speed is the most economical，The fuel consumption is also the lowest。

Driving habits are very important

Many people are most motivated to drive，The accelerator and the brake will be very urgent，This fuel consumption is the biggest。Try not to open the window，After opening the window, the resistance of the car will become larger，and make the canopy very dirty。After the car runs up, if it is not an emergency, try to use the mobilization mechanism to control the speed。Such fuel consumption will be relatively small，The brake pads are not easy to wear。

Summary

We understand the principle of upgrading the automatic transmission vehicle and do it.，Develop good driving habits。can better reduce the fuel consumption of the car。If you do not follow the routine card，The car becomes a "oil tiger".。

Do you usually drive like this?
