The electronic throttle controller (also known as the electronic throttle accelerator) can provide the driving computer with the function of accurately controlling the air entering the engine. With a relatively gentle opening and closing speed, the driving computer can calculate a more accurate fuel injection amount, which has achieved a more environmentally friendly and fuel-efficient combustion condition. However, this will also lead to the pedal reaction of the throttle can not be like the traditional cable throttle Sensitive; for this reason, a product called electronic throttle controller will appear on the market to improve the slow response of the throttle, which is also the result of TROS throttle controller.
In order to calculate the correct fuel injection quantity, the driving computer needs to read the signals returned by many sensors to determine the fuel injection quantity. The types of these sensors include: air flow meter, throttle opening signal, engine speed, water temperature, oxygen sensor, etc. However, the computer passively receives the signals to control the fuel injection quantity, so once the sensor signals The instantaneous change is too large. For example, if the throttle is opened or closed, the computer may not be able to calculate the most appropriate fuel supply immediately, so the engine will have a "fuel consumption" situation, so there will be an electronic throttle.
The principle of the electronic throttle is to install a pedal angle sensor on the accelerator pedal, which is responsible for turning the pedal depth into an electronic signal and then sending it back to the fuel supply computer. The computer then controls the servo motor on the throttle according to the engine speed, gear, load and speed at that time, so that the butterfly valve on the throttle can do the opening action. The main purpose of making the trip computer responsible for the control of throttle opening is as follows:
First, it can make the throttle do the best opening rate under different loads to achieve the balance of air flow rate and flow rate;
Second, to slow down the throttle action speed, because it is controlled by the servo motor, the butterfly valve's reaction speed can be controlled differently according to different rotating speeds, so that the computer can keep up with the change of air intake, and then calculate the optimal fuel injection quantity; in addition, idle speed increase, cruise speed control or anti-skid control can also be achieved through the electronic throttle controller.
For the views above, it is not difficult to find that the biggest advantage of electronic throttle is to save fuel consumption, but in this way, it is easy to produce the situation that the response of throttle becomes slow, the force path of oil return and re acceleration is half beat slow, even the problem of slow starting. However, since it is electronic signal to control the throttle, as long as appropriate optimization and adjustment are made to this signal, the throttle response can become sensitive or slow, so as to provide high performance or fuel saving effect, which is exactly the principle of the electronic throttle controller. As an old brand manufacturer, TROS electronic accelerator has many years of R & D and production experience, with stable performance The power improvement effect is obvious, the speed change is very linear, and many additional functions are added, further improving the value of the product.
