Is the electron accelerator useful?

Electronic throttle throttle can amplify the throttle signal and control the opening and closing of the throttle again. When stepping on the accelerator pedal, the signal of the accelerator pedal position sensor is collected, and the rearranged accelerator signal is transmitted to the computer to improve the response performance of the engine, thereby improving the sensitivity of the accelerator, speeding up the starting speed, and finally achieving the effect of instantaneous speed increase.

Generally speaking, fuel consumption is related to personal driving habits. Setting the semi-acceleration mode with electronic throttle basically does not increase fuel consumption, and the throttle responds faster and lighter, and the power is improved. In other words, if you want to get the same power as before, you can use less force when stepping on the accelerator, which is helpful for fuel consumption.

However, if the full acceleration mode is started, the fuel consumption will increase by 0.5- 1 oil. If the original car has weak power and heavy body, the depth of the accelerator pedal will be greater and the fuel consumption will increase.

Extended data

The electron accelerator will have the following characteristics:

(1) Amplifies the throttle signal to improve the static response.

The so-called "acceleration" of electronic throttle is mainly realized by improving the sensitivity of throttle response, which will amplify the input throttle signal by 50%. That is to say, at any time, the last 33% throttle signal is useless, and the throttle output is full throttle when the driver depresses the pedal 66%, which improves the throttle response sensitivity by 50%.

However, the electronic throttle does not reduce the classification of throttle signals as many people say. In fact, the throttle signal is infinitely adjustable, only from the previous 1: 1 to 1. X is the amplification factor of the signal.

(2) Increase the speed of throttle signal and improve the dynamic response.

When the accelerator pedal is depressed, the accelerator will calculate the change rate of the accelerator signal according to the depressed amplitude and time. The faster the change, the stronger the acceleration requirement, and the accelerator will increase the change rate, and the final effect is better dynamic response.

(3) Provide virtual driving style for ecu to adjust engine parameters.

The ecu of modern engine generally has the adaptability of driving style. If the driver often steps on the accelerator quickly and deeply (commonly known as pulling speed), ecu will gradually think that the driver's style tends to be "intense", so that the engine will slowly adjust the accelerator and fuel injection system to obtain the best adjustment parameters of the engine under this style.

After using the electronic throttle, even if the engine is driven according to the previous "gentle" driving style, the engine will still get a "fierce" driving experience, which is equivalent to cheating the ecu. Over time, the engine will automatically modify its parameters to adapt to this style.
