Recently, Toyota can be said to be a leader in repeatedly jumping sideways to do things!
First of all, the use of defective parts to build a new car, two days ago and suddenly held an electric vehicle strategy conference, announced that it will invest 35 billion US dollars in electric vehicles before 2030, but also to launch 30 electric vehicles, its luxury brand, Lexus will also bid farewell to fuel and become a pure electric brand.
Car owners who pay attention to the industry know that Toyota Akio has been a determined electric vehicle black for many years, and two or three months ago, he just made another statement about shelling electric vehicles and was overly concerned.
I have to say that Akio Toyoda really "transmuted" and changed fifteen times in one breath.
Punch yourself in the face and hit it
Hey, who in front of you is so backbone, vibrating and wordy?
If you want to make money, don't be humble, but don't be a jerk again.
After all, the development of science and technology is not subject to human will!
Well, without further ado, let's start today's sit-in session!

Tiger, I just bought the Ten Generation Accord this year, the fuel version of the cvt transmission. Lent to a friend for a day. Came back and found that the throttle was empty. The speed lows are not too severe. The speed is fast, the void is serious, and the speed rises, and the speed is significantly delayed. How about that?
Results of Tiger Sitting:
First of all, Tiger first threw out the answer to the question "ECU learning"
That's right, ninety-nine percent of the throttle can't have a vacancy. Your engine is already an electronic throttle EFI engine. The throttle is simply a sensor that collects a position signal like a sliding varistor or encoder. The engine's computer calculates how much gas to feed and how much oil to inject based on the throttle you are stepping on.
So when you step on the accelerator and issue an order, the computer says that it has received a power request instruction, please increase the intake of the throttle motor, and increase the injection pulse of the fuel injector, and then the power can come up. Therefore, you see that the power release is completely different from the era of carburetors, which has a process of information transmission processing, which has a certain lag relative to the mechanical throttle.
At the same time, if you forcibly step on the deep throttle, the computer finds that the air-fuel ratio is too outrageous, the emissions are not up to standard, I can't do it, and then give the throttle and the injector a move instruction that it thinks is appropriate, which is equivalent to your partial power request exceeding its ability, and it will not come according to you. The carburetor car is not the same, you give the throttle, he will inject oil vigorously, no matter how the exhaust gas is discharged, it costs no oil, and it is dry to death.
So what exactly should the owner do to get back to the previous power response? Quite simply, just leave him alone and keep driving! The ECU will relearn the record data based on your original driving habits.
Because the vehicle will have some deviations from assembly to the owner's use, the most intuitive feeling about this is that when the manual transmission is opened, the feeling of stepping on the clutch of each car will be different. Then during long-term use the clutch itself also wears out.
We often say that new cars need to be "run-in" for a period of time and then in better shape, which also has the credit of self-learning.
Therefore, after driving for the pot friend, the power becomes smaller, and the general reasonable situation is that the ECU has made corresponding changes according to the driving habits of your pot friend.
The car was naturally just fine in two days

Tai Ge good, automatic start and stop when I drive will not deliberately close, because the start and stop can be controlled by their own braking force! I usually only have a red light above 50 seconds before I will deeply press the brakes, use the start-stop function, I will not save fuel in this way? And destroy the car?
First of all, the conclusion: not exactly chicken ribs, can save fuel, almost does not hurt the car.
Of course, if you can tolerate the few aspects that most people consider to be shortcomings, then it is practical.
Bosch of Germany once did an experiment, the specific process will not be repeated, they finally came to a conclusion - the average fuel saving efficiency of automatic start and stop is 8%-15%, and the more blocked, the larger the displacement, the better the effect.
Although it can save you fuel, there are still many riders who will turn it off after getting on the car, and think that if it is not turned on by default. So why is it that a good design has become a chicken rib?
The main worries of car owners are only a few:
Injury engine, in fact, will not damage the engine, automatic start and stop is a kind of hot start and stop technology, cold car is not working, cold start will hurt the engine. Combined with special starters and special designs, the life of vehicle components will not be reduced.
Cars with automatic start-stop capability, the power and torque of the starter are far more "arbitrary" than the traditional starters. Because in the automatic start-stop system, the manufacturer's design requirements are often to specify a smooth start of the engine within 1 second. This is not such a strict requirement in traditional car design.
Injuring batteries is a real problem
Some people say that saving fuel always saves more money than changing batteries. Yes, but let's roughly calculate an account, according to the data, the average mileage of China's car in a year is 18,000 kilometers; then open the automatic start and stop, a year can save about 84 liters of fuel, that is, about 550 yuan.
The automatic starter type has very strict requirements for the instantaneous large current release ability of the battery. Therefore, we need to know that models with automatic start-stop capabilities and batteries carried by the original cars are special batteries! That is to say, their batteries and the batteries of traditional cars are not the same thing!
Ordinary car battery 300 is not done, the automatic start and stop of the battery because of frequent discharge requires a high price of 1500 yuan - according to the car maintenance three years a battery replacement, the battery price difference of 1200 yuan.
With automatic start and stop for three years, the fuel cost saves 1650 yuan, the battery difference is 1200 yuan, in fact, you save 450 yuan in three years, and save 150 yuan in one year.
This 150 yuan will have to endure frequent vehicle shaking at startup, although the car company has done a lot of optimization in this regard, but there is still obvious shaking. There is also the one-second lag at the green light, although it is short, but the cars in the queue behind do not think so.
