The best time to shift

    1. With regard to engine power:

Automobile Engine maximum power is brought into play in a certain speeds, so the car brochures or promotional materials where the note is on power and speed on a par. When the car when the engine low-speed driving (for example, 1500RPM), engine power may only play 10% -15% (the specific parameters of the engine you have to study your “speed / power curve” will be able to determine, if you any . Moreover, this function is the derivative curve is not smooth, hehe). Transportation to Taiwan JC said at the time: “as if the car needs 70 horses pulling the original (engine a maximum power of 70 horsepower), you now only allow 15 Mara, can not effort it?”

2. With regard to combustion:

A long time in the low engine speed state of the work will cause burning inadequate, and some parts will be coke, and some parts will be sticky sticky paste is not fully burning grease to live, resulting in further combustion is not sufficient, a vicious circle. By that time, your car does not want the meat is also difficult. Transportation to Taiwan the day of the examples JC said: “The reform and opening up, China’s ministries and bought a large one world-famous brands of high-level cars (JC did not name, I guess the big Ben), to the professional drivers do not open the year, on the fuel rise, running down, and so have been a negative phenomenon. Fenfen Ran ministry summoned the leadership of the company’s Beijing office in the old Germany, questioned the quality of their products. the old Germany came after the first own car and turn in the yard 2 laps, the driver usually asked the question how to drive, how to file maintenance and timing of addition and subtraction, etc., and open the car probably looked at the machine lid. and then to the leadership of the old Germany, said: Sunday (when no weekend) morning, 6:00, please have the driver fill up the car at the starting point Jingshun waiting for me, I personally give you repair. the driver early Sunday morning, came to the agreed location, and my heart still straight wonder how this old German repair here? 6:00 the whole to the old Germany, and also opened a big Ben, he was off the professional driver said: Do you follow me, do not pull down. Having turned and bolted on the train speed will soon reach 200KM / H, has been open to the Miyun Reservoir, the dam was stopped (Journey time is approximately 200KM). Germany, the old man out of the car smiling driver of China, said: car has been repaired. tried the drivers drove slowly in situ is indeed a lot. the old German explained said: You had the habit of opening the car is your Chinese habits, to open our company car according to our instructions on the habits and requirements, you long-term low stall speed increases, making combustion inadequate sticky messy oil to spray nozzle and other parts are all paste lived. Today, let’s open so fast, speed more than in 4500-5000, the oil flow will be large, the original sticky sticky things are washed away. so good and opened the car . “I heard later that there may be factors that Peking Man Kanda Shan (JC is a true story) it is not so Xiehu do not know, but the truth is very clear.

3. On how to fuel-efficient:

The long-term low-speed driving the engine will make the engine work state of decline in combustion is not sufficient. Fuel consumption will certainly rise. Let’s state the driver, but it was such a study (and I am also such a school, my coach was driving the gold sea coach driving experience over 40 years, he told me earnestly teaching: a moving car on the plus-two stalls!), Low speed add files and provinces in order to fuel-efficient vehicles. Indeed fuel-efficient, and why? I see and then the driver will repair a relationship, he would be bored nothing to put the whole engine apart, rub inside and outside again revised again, but now let’s standards and requirements of joint-venture car apparently is not allowed. And then the Chinese engine and vehicle, from the materials, design, to the poor standard of work and commissioning levels can not accept high-speed and high-speed test, so only low-speed low-speed. Now I open Jetta Ci, 3000RPM plus stalls, a tank of fuel to run 720KM Tan (and I often run along the Fourth Ring, He He) is not evidence of oil.

4. With regard to the life of the engine and driving pleasure:

In accordance with the engine was originally designed to work at a higher speed, and various parts of the dynamic balance and moment of inertia and other parameters are also under high-speed design of the reference value, if the engine a long time in the non-normal working mode of operation the internal parts of the load and wear of natural increase, jitter and frequent phenomenon called the bachelor life I am afraid that should be affected. Your own car more and more meat, driving pleasure also vanished. I think the Jetta car when the engine speed of 3000-4000 the most effort, who wish to bring up who is to blame when overtaking. Hehe.

5. With regard to file a smooth and noise addition and subtraction problems:

Modified profile is smooth, mainly depends on the oil from the line with technology. I 3000RPM plus stalls, very smooth. What do you think 3000RPM stall when the noise increases ugly? I 2000-2500RPM plus stalls, the old German is very tactfully said to me: “Do you not hear the engine send a very nasty voice?” Oh, I drive his car, look at his sad about it. What is the sound speed of the engine under it nicely, I am afraid the problem is also a point of view. Yet another reason for this is, let the car too bad. I sat the best car is a BENZ S600, engine speed is never too high to hear it. Buick good too. Again, the higher the addition and subtraction file stalls the more stable is a normal phenomenon, and different gear transmission ratio is not the same as the middle of a relationship.

6. With regard to a file plus two files need special attention:

Old German car got started, a file transfer speed of the general to the 4000 (also 5000 rpm) before adding two files, I originally thought it was a driving style, later discovered that everyone is behaving like. Plus two stalls in a stall speed of 40KM or so has been basically achieved, this is such a more general public at large or the Ford of foreign cars, if Porsche car, I think it is probably a speed-plus-two stalls in the 70-80KM / H (which are no rare, Porsche design speed of more than 300, six forward files). Asked in detail later learned that the German car is so taught in school, and started when the stall speed increases to be particularly high. The reason is when the car starts, the required maximum power (not just a DX article says the car a significant decline starting on the frictional resistance, the resistance is negligible for the car, on the ground, I use a leg will be able to top touch my Jetta), which power is used to overcome the inertia of the car, (gasoline combustion heat transformed into kinetic energy), and a file transmission than the minimum, maximum vigor, we must maximize. And then the Germans to accelerate very fierce, the reason is to keep the engine work in the 2000RPM below.

7. Look at the tachometer may also be helpful:

I do not know Fukang car speed reflected in Shayang? But my Jetta car tachometer, from 2000-4000RPM is a green flag (Changchun do not know when the public improvements, the original did not) This is a very clear sign — Health rotating speed. In Germany, the basic open highway speed, most cars are in for 150-180KM / H speed of a long drive, 200KM per hour over the motorcycles and cars for more than 250KM very common, when the engine speed probably will be 5000 above. Think they will understand, he ran five 140-150KM stall speed of the engine speed would have been more than 4000, you may often be so, why a file, two files when you are not out? By the way, why did I choose 3000RPM as the transfer increases the number of files? Because my car just after the 3000 switch to increase file transfer is more than 2300, which can guarantee that my engine is always working in health, within the range of speed, it can make you healthy healthy, always healthy!

2000 Conversion file is lower the lower limit would normally be 2500-3000, because the engine-specific. A more simple method of measuring gear speed is first in the two files (or 3 files) on the drive, be sure to find a certain speed, when the throttle to reflect the most sensitive, light-point throttle vehicles will forward string, remember when speed of, say, 3000 forward, then the shift on the left in 3500, the economy can shift a little 3200, and 3800 can be a little fierce pulls.
Uniform traffic can be augmented by a further 1 file (MPG). For example, or that 3000 turn, third gear, 50KHM, if the uniform driving (50KMH), which can be attached to the fourth gear, want to further reduce back to third gear when accelerating. Prop file to avoid oil, hurt the engine. Counter-to-high switch would not hurt the engine in Germany, driving habits are little lower than the stall speed by 4000, on the highway coaches requirement is increased to third gear 100KMH, to directly push the five-speed. 2 file 20, 3 stall 30, the method is not very good, fuel-efficient is a certain, but most vulnerable to large accelerator can speed again able to come up, there is no more hurt than this engine, and this method is not suitable for novice.

I observations: speed gear change, at least at the maximum speed torque calibration value (car description —- on both engine technology parameters), then also it should be larger, there is no good, there is no high-speed engine is not Well, if the delay block if, instead, hurt the engine! !

2000 conversion block, is not even barely have enough to do not last? No really! Whether the engine is still Europe and the United States, Japan, the 2000 is not transferred to the engine caused by fuel-efficient, but the injury!

In fact, this issue really was not any discussion of the significance of the number of rotational speed of the shift, the easiest way is to look at your car manuals on the engine maximum torque of rotation on the line, shift can not be lower than it!

I have 3 block, sometimes often open until 80, four block and sometimes 100, sometimes skip a gear directly into 5-speed. Like track and field competition in the 4X100 relay, like to play a maximum capacity of each rod must be the end can there be good results. There’s really nothing, and anyway this would not hurt the engine, making the engine was fuel-efficient living rather than in the low rotational speed of each block, the low-speed high gear the engine will not work properly, incomplete combustion caused by coke, but also will pollute the EFI system, or even plug the nozzle, disrupt the normal operation of the computer board.
