What happened when Ariza 5 didn't increase the throttle speed?

Arrizo 5 is an electronic throttle. Generally, the electronic throttle will have a delay of about 1 second, which is normal. When stepping on the accelerator, you can increase the speed and speed or turn off the ECO, which will improve the slow response of the accelerator.

The slow throttle response is due to the engine throttle characteristics of TSI, which is slower than the power output of natural inhalation, but stronger. Because drivers usually have fierce driving habits, they step on the accelerator too deeply and too quickly. At this time, the gearbox does not respond well, which will also cause the throttle to respond slowly. In another case, when the engine speed is low, the exhaust gas is not enough to drive the turbine to run, which will also cause the throttle response to be slow. At present, most models are gradually converted into electronic throttle, which is inherently slower than the traditional cable throttle. After all, it takes time to perform the process of induction+signal generation+signal transmission+signal analysis+control execution. Therefore, it is most important to develop good driving habits and have a calm mind.

If the fault of electronic throttle is eliminated, we should turn our attention to the three systems of the engine: air intake, oil circuit and ignition. Just mentioned the signal of the throttle position sensor. In fact, it is a member of the air intake system, and the normal operation of the engine requires sufficient air. The air intake system leaks or is blocked, the power drops when the car refuels, the speed can't go up, and the body shakes.
