What's the use of a car throttle? What is the correct way to use it?

The accelerator is called "accelerator pedal" in the structure of motor vehicles. When driving a motor vehicle, when you need to accelerate or meet reinforcements, you must step on the accelerator pedal to improve the engine power and torque, which is usually called "refueling", but from the conventional terminology, "accelerator" seems to be coming. If you control the oil, the throttle is deep, as if there is too much oil, and the throttle is very shallow, as if it is the amount of oil. Is that really the case?

What's the use of cars? Long ago, the accelerator pedal was mechanically connected with the engine. At that time, the throttle valve directly controlled the oil quantity. The auto time of oil and gas is controlled by throttle stretching. The throttle opening of the fuel grille is very large, the air flow of the cylinder increases, the chemical oil is blown out in the airflow, and the throttle opening increases. Fuel supply will increase, engine speed will increase and engine speed will decrease.

But now, the engine of the engine is controlled by the driving computer, and the throttle actually controls the throttle, which is the full name of throttle body. The sensor next to the throttle is called the throttle position sensor, which can transmit the throttle opening signal to the driving computer in the form of voltage. The driving computer calculates the injection quantity according to this signal and other signals, and controls the fuel injection of the injector. The greater the throttle opening, the greater the fuel injector calculated by computer, and the higher the engine speed. or vice versa, Dallas to the auditorium

Specifically, the throttle size is the angle of the throttle opening, that is, the degree of the pedal that controls the intake. Next, the sensor transmits the received signal to the drive computer. Under the setting conditions of the computer, the air-fuel ratio of the mixed gas is calculated by measuring the intake air volume and air-fuel ratio; Of course, this is also a batch correction signal, such as intake air temperature, and then the engine speed changes, resulting in changes in power and torque.

I hope my answer can help you, and I hope you can help me forward it, like it, support me more and pay more attention to me. If you have any questions or requests, you can leave a message in the comment area, and I will reply them one by one.
