When the throttle opening increases, what gear does the automatic transmission shift?

So let's talk about how the throttle works first.

The opening and closing of the throttle is related to the amount of fuel injected into the engine, that is, when you start the engine, the throttle will open, but it will not open very much. Of course, when stepping on the gas pedal, the gas pedal will open halfway, and when stepping on 3/4, the gas pedal will open completely, which has nothing to do with the gear position. .

But this is only for common low-end cars. . Then there is BMW's function of variably closing the exhaust valve, that is to say, BMW has a stepless variable throttle opening mode. When we step on a certain throttle, the throttle can be changed: "stepless", and Honda has also developed a "variable timing control valve" system, which is our common VTEC engine, so this technology can control the size of the intake throttle, but it has a series. . Toyota also has the same type of products. .

More advanced cars, as well as the adjustment chain of camshaft angle change and so on. .

To sum up, the throttle opening has nothing to do with the gear of any vehicle. .

There is a simple reason. In order to make the fuel burn fully, it is necessary to have enough intake air. The optimum mixing ratio is114.7. In other words, stepping on the gas pedal can't speed up crazily, but it costs oil (of course, it also helps). Therefore, the control system of throttle opening directly determines the performance of the engine.
