What are the advantages and disadvantages of electronic throttle accelerator?

　　Because of environmental protection, economy, reliability and other reasons, electronic throttle is now widely used in newer models. What are its shortcomings and some points? Let's have a look.

　　I. Advantages of Electronic Throttle Accelerator Manufacturers

　　1. Amplify throttle signal to enhance static response

　　The so-called "acceleration" of electronic accelerator is mainly achieved by improving the sensitivity of accelerator response. That is to say, 33% of the accelerator signal at the end of the pedal is useless at any time, and the accelerator output is full throttle when the driver steps down 66%, which makes the sensitivity of accelerator response increased by 50%. In fact, the throttle signal has been steplessly adjusted, only from the previous 1:1 to 1:1.x, x is the signal amplification factor. (For example, after installation, you can adjust half-open or full-open, that is, you can adjust the proportion to 1:1.5 or even 1:2).

　　2. Amplify the acceleration of throttle signal and enhance the dynamic response

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

　　2. Disadvantages of Electronic Throttle Accelerator Manufacturers

　　1. Increased difficulty in oil separation and coordination of manual vehicles

　　When the manual gear vehicle is added to the accelerator, the response of the accelerator pedal is too sensitive, and more precise oil separation coordination is needed to achieve the previous effect. This is very similar to the influence of clutch depth on the smooth start. The deep clutch is easy to control, but the operation stroke is large; the shallow clutch has a short operation stroke, but the control is difficult, so is the impact of the throttle pedal on the start.

　　2. Increasing fuel consumption

　　Because the accelerator improves the throttle response, which is equivalent to a more "intense" style of driving, this will undoubtedly increase fuel consumption, but the increase in fuel consumption is not very high. The actual fuel consumption measured by the fleet more than two years ago increased between 5% and 10%, which is acceptable to those who are interested in driving.
