变速箱的升降档方式

Upshift and downshift mode of speed box
开过手动挡车子的人都知道。开手动挡车子的时候车子车速跟转速上来了就要人工换挡,路况不好的时候要降档。发动机的动能→→机械能。离合那器完全结合后效率高。
Anyone who has driven a manual transmission knows. When driving a manual car, when the car's speed keeps up with the speed, you have to shift gears manually. When the road conditions are bad, you have to downshift. Kinetic energy of engine → mechanical energy. After the clutch is fully combined, the efficiency is high.
那么自动挡车子它是自己自动升降档的,它的能转换是发动机动能→→液能→→动能,效率先大概在80左右,但是车速达到一定时,液力变矩器会锁住等于是机械传动效率90。它是怎么自己升降档的?首先要根据节气门的开度(反应出发动机的负荷),还有就是根据车子的车速。比如说车子现在的车速是30km/h,节气门的开度都已经达到40,那说明车子现在是以低速行驶,发动机的负荷比较大。这时候变速箱就会降档,反之。
Then, the automatic transmission vehicle has its own automatic lifting gear. Its energy conversion is engine kinetic energy → hydraulic energy → kinetic energy. The efficiency is about 80 first, but when the speed reaches a certain speed, the hydraulic torque converter will lock, which is equal to the mechanical transmission efficiency of 90. How does it shift up and down by itself? First of all, according to the throttle opening (reflecting the load of the starting engine) and the vehicle speed. For example, the current speed of the car is 30km / h and the throttle opening has reached 40, which means that the car is running at a low speed and the engine load is relatively large. At this time, the transmission will downshift, and vice versa.
让自动变速器升档快一点
Let the automatic transmission upshift faster
要想车子开起来省油那要让变速器尽快升档,这样传动比会比较小,效率会比较高。按照我们的理解就是起步的时候踩大点油门,让车子快点跑起来,觉得这样会省油。其实这样子做是错了。自动挡的车子平时起步的时候要轻踩油门,车速稍微上来一点之后要轻轻松一点油门踏板然后再轻踩。这样子做变速器就会立马上升一个挡,因为你这样操作变速器的控制单元收到油门踏板的信号的小负荷,它就会上升一个挡,效率就会提高。
If you want to drive the car to save fuel, you should make the transmission upshift as soon as possible. In this way, the transmission ratio will be relatively small and the efficiency will be relatively high. According to our understanding, when starting, step on the gas pedal to make the car run faster. I think it will save fuel. In fact, this is wrong. When a car in automatic gear starts, it is necessary to step on the accelerator gently. After the speed rises a little, it is necessary to step on the accelerator pedal gently, and then step on it again. In this way, the transmission will immediately rise by one gear, because if you operate the transmission in this way, the control unit will rise by one gear when it receives a small load from the signal of the accelerator pedal, and the efficiency will be improved.
车速不能开太快
Don't drive too fast
车速慢了油耗会变大,但是并不是说车速越快就越省油。因为车子开得太慢的话效率会太低,开得越快收到风的阻力就会越大。我们的经济车速是让变速器上升到了较高的档位时油门踏板踩到大概五分之三的位置。车子的车速大概是80~100之间,这个车速是较经济,油耗也是较低的。
The fuel consumption will increase when the vehicle speed is slow, but it does not mean that the faster the vehicle speed, the more fuel-efficient it will be. Because if the car is driven too slowly, the efficiency will be too low. The faster you drive, the greater the resistance to the wind. Our economic speed is to press the accelerator pedal to about three fifths when the transmission rises to a higher gear. The speed of the car is about 80 ~ 100. This speed is economical and the fuel consumption is low.
驾驶习惯很重要
Driving habits are important
很多人开车较求动力,油门跟刹车都会踩得很急,这样子操作油耗是较大的。尽量不要开窗,开了窗之后车子的阻力会变大,而且弄得顶篷很脏。车子跑起来之后如果不是紧急情况的话要尽量利用发动机制动来控制车速。这样油耗会比较少,刹车片也不易磨损。
Many people drive for power. They step on the accelerator and brake very quickly. In this way, the fuel consumption is large. Try not to open the window. After opening the window, the resistance of the car will increase, and the roof will be very dirty. After the car runs, if it is not an emergency, try to use the engine brake to control the speed. In this way, the fuel consumption will be relatively low, and the brake pads are not easy to wear.
