What is the use of the two tubes with antifreeze for the throttle

The function of this line is to control the engine to warm up and idle quickly.

, meaning the throttle when the temperature of the vehicle is low.

There is an air intake duct that can increase the air intake at this time to increase the idle speed of the engine, and when the engine water temperature rises, it is bypassed due to the action of these two water pipes.

The opening of the intake tract is gradually reduced, so as to reduce the air intake volume and gradually restore the normal idle speed of the vehicle, so as to achieve the purpose of rapid warm-up.

The tube on the throttle valve is basically a vacuum tube, one is EGR (exhaust gas recirculation), the other is for brake vacuum drum vacuuming, and the third is for cold car speed.

Throttle Valve is a controllable valve used to control air entering the engine, which enters the intake pipe and mixes with gasoline (different styles of cars, different design mixing parts) to become a combustible mixture of gas, which participates in combustion work. Four-stroke gasoline engines are roughly like this. The throttle valve is the most important part of the engine system of today's EFI car, its upper part is the air filter, and the lower part is the engine block, which is the throat of the automobile engine.

Whether the acceleration of the car is flexible or not is very related to the cleaning of the throttle. Whether the throttle should be removed and cleaned is also the focus of much discussion among car owners.

These two water pipes are used to heat the incoming air, when the cold starts the air from the idle motor hole, when the water of the engine reaches a certain temperature, the air flows through, which is for the air heating, and then in order to provide good combustion, the combustion is good, and the idle speed is otherwise stable. In a word, it is to provide heating for the air, in order to stabilize the idle speed quickly, especially in winter.

The water pipe here is for heating the throttle body! The flow velocity of air out of the throttle valve is large, and it is easy to freeze in winter! In order to avoid this situation, hot water is drawn from the cylinder head to heat the throttle body, which belongs to a small cycle.

The water temperature is kept at around ninety degrees.

It is to prevent the throttle from freezing, and it is also to increase the intake air temperature and improve the combustion performance of the cylinder;

It's not heating, I think it's cooling.

It is to prevent the throttle from freezing

Preheats the air for precise control of the air temperature.

The function of the pipeline is to control the engine warm-up and slow idling, which means that when the temperature of the vehicle is low, there is an air inlet out of the throttle valve to increase the air intake at this time, so as to improve the idle speed of the engine, when the engine water temperature rises, due to the action of these two water pipes, the opening of the bypass air inlet is gradually reduced, so as to reduce the amount of air entering the vehicle and gradually restore the normal idle speed of the vehicle, so as to achieve the purpose of rapid hot car.

1. The tube on the throttle valve is basically a vacuum tube, one is EGR (exhaust gas recirculation), the other is for brake vacuum drum vacuuming, and the third is for cold car speed.

2. The working principle of the electronic throttle is: through the sensor on the oil and gas pedal, the computer detects and controls the amount of fuel injection for the amount of air intake, and the heavier the step, the throttle opening is large, and the air intake is more, the computer will automatically adjust the corresponding fuel injection amount according to the parameters, and the heavier the fuel injection, the more fuel injection.

3 Not all automatic transmissions are electronic throttle, which is based on the configuration of the model, and the work of automatic transmissions is basically: P parking gear. r reverse gear.

D automatic gear, some models also have S gear or L gear, all according to the gearbox configuration, D gear is generally four gears, some cars are five or six gears. After hanging into the D gear, according to the engine speed, the number of kilometers, the computer will automatically jump from the first gear to the second gear, the third gear and the fourth gear, but there is a premise, it must be after the car walks up, let go of the throttle and then step on, the automatic gear will automatically jump up, if the car steps together, it can be held throttle is not loose, so that the original gear is a few gears will not jump, can only feel the speed of the car up, let go of the throttle and then step on, let it jump gears by itself, otherwise the computer will think that you are uphill, will not automatically change gears. The automatic transmission mentioned upstairs is infinitely variable gear, which is different from the automatic transmission.

And the automatic transmission has been around since the sixties

The tube is a vacuum tube and a water pipe, the electronic throttle is the foot pedal that has a sensor, the sensor gives the computer board a signal, the computer controls the motor stroke in the throttle body according to the signal, the automatic transmission and the electronic throttle are not the same thing, the automatic transmission is from the start to the driving only one gear, the automatic transmission appeared relatively early, there was an automatic transmission in nine years, and the electronic throttle valve appeared after the appearance of the EFI engine.

1. What are the many tubes on the throttle for, can you briefly explain them one by one (thank you).

2. What is the principle of the electronic throttle and how to control it and the electronic accelerator pedal?

3. Is the automatic transmission an electronic throttle?
