變速箱的升降檔方式
Upshift and downshift mode of speed box
開(kāi)過(guò)手動(dòng)擋車(chē)子的人都知道。開(kāi)手動(dòng)擋車(chē)子的時(shí)候車(chē)子車(chē)速跟轉(zhuǎn)速上來(lái)了就要人工換擋，路況不好的時(shí)候要降檔。發(fā)動(dòng)機(jī)的動(dòng)能→→機(jī)械能。離合那器完全結(jié)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.
那么自動(dòng)擋車(chē)子它是自己自動(dòng)升降檔的，它的能轉(zhuǎn)換是發(fā)動(dòng)機(jī)動(dòng)能→→液能→→動(dòng)能，效率先大概在80左右，但是車(chē)速達(dá)到一定時(shí)，液力變矩器會(huì)鎖住等于是機(jī)械傳動(dòng)效率90。它是怎么自己升降檔的？首先要根據(jù)節(jié)氣門(mén)的開(kāi)度(反應(yīng)出發(fā)動(dòng)機(jī)的負(fù)荷)，還有就是根據(jù)車(chē)子的車(chē)速。比如說(shuō)車(chē)子現(xiàn)在的車(chē)速是30km/h，節(jié)氣門(mén)的開(kāi)度都已經(jīng)達(dá)到40，那說(shuō)明車(chē)子現(xiàn)在是以低速行駛，發(fā)動(dòng)機(jī)的負(fù)荷比較大。這時(shí)候變速箱就會(huì)降檔，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.
讓自動(dòng)變速器升檔快一點(diǎn)
Let the automatic transmission upshift faster
要想車(chē)子開(kāi)起來(lái)省油那要讓變速器盡快升檔，這樣傳動(dòng)比會(huì)比較小，效率會(huì)比較高。按照我們的理解就是起步的時(shí)候踩大點(diǎn)油門(mén)，讓車(chē)子快點(diǎn)跑起來(lái)，覺(jué)得這樣會(huì)省油。其實(shí)這樣子做是錯(cuò)了。自動(dòng)擋的車(chē)子平時(shí)起步的時(shí)候要輕踩油門(mén)，車(chē)速稍微上來(lái)一點(diǎn)之后要輕輕松一點(diǎn)油門(mén)踏板然后再輕踩。這樣子做變速器就會(huì)立馬上升一個(gè)擋，因?yàn)槟氵@樣操作變速器的控制單元收到油門(mén)踏板的信號(hào)的小負(fù)荷，它就會(huì)上升一個(gè)擋，效率就會(huì)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.
車(chē)速不能開(kāi)太快
Don't drive too fast
車(chē)速慢了油耗會(huì)變大，但是并不是說(shuō)車(chē)速越快就越省油。因?yàn)檐?chē)子開(kāi)得太慢的話(huà)效率會(huì)太低，開(kāi)得越快收到風(fēng)的阻力就會(huì)越大。我們的經(jīng)濟(jì)車(chē)速是讓變速器上升到了較高的檔位時(shí)油門(mén)踏板踩到大概五分之三的位置。車(chē)子的車(chē)速大概是80～100之間，這個(gè)車(chē)速是較經(jīng)濟(jì)，油耗也是較低的。
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.
駕駛習(xí)慣很重要
Driving habits are important
很多人開(kāi)車(chē)較求動(dòng)力，油門(mén)跟剎車(chē)都會(huì)踩得很急，這樣子操作油耗是較大的。盡量不要開(kāi)窗，開(kāi)了窗之后車(chē)子的阻力會(huì)變大，而且弄得頂篷很臟。車(chē)子跑起來(lái)之后如果不是緊急情況的話(huà)要盡量利用發(fā)動(dòng)機(jī)制動(dòng)來(lái)控制車(chē)速。這樣油耗會(huì)比較少，剎車(chē)片也不易磨損。
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.
