What does a car throttle do? What is the function of the throttle?

The throttle valve is a controllable valve that controls the entry of air into the engine, and the gas enters the intake pipe and mixes with gasoline to form a combustible mixture, thus combusting work. It is connected to the air filter and the engine block, which is known as the throat of the automobile engine. There are two types of throttle valves: traditional cable-based and electronic throttle.

The function of the throttle valve is to control the intake flow of the engine, which is a controllable valve that controls the air to enter the engine to determine the operating conditions of the engine.

1. Increase power by accelerating or decelerating;

2. Through its self-adjustment, the air intake function is corrected;

4. The function of controlling the operation of the engine assembly (the idle switch inside the engine is working);

5. Control the flap, control the size of the air intake through the work of the sensor, and use it for the lifting of power;

The function of the throttle is to control the air intake of the engine, and the throttle is commonly known as the throttle that is controlled.

The main function of the throttle valve is to control the amount of air intake according to the load of the engine.

The throttle is installed on the engine, which is used to control the amount of oil entering the cylinder combustion (commonly known as the throttle), the larger the opening, the more fuel mixture enters the cylinder, the higher the engine speed, and the opening of the throttle is changed, so as to control the engine speed;

As for how often to clean, it is determined by many aspects. For example, the driving environment of the vehicle, the control mode of the EFI engine, etc.

If the vehicle is working in a relatively polluted environment (mainly referring to inhalable particulate matter), impurities will quickly accumulate on the throttle, and over time, it will affect the air intake of the engine, and then it needs to be cleaned. This phenomenon is most noticeable when starting the vehicle.

For example, some Japanese engine control systems traditionally prefer to calculate the time of fuel injection and ignition by measuring the air flow. Therefore, the accuracy of air flow measurement is very strict. A slight blockage can also cause the engine to work abnormally.

But for some American engines, which do not use air flow as the basis for calculation, there is not such a big response.

Therefore, different vehicles and different working environments will cause inconsistency in the cleaning time of the engine throttle. There is no rule for how often the throttle should be cleaned. If there is such a regulation, it is an abnormal regulation, indicating that the car is defective in its design.

The throttle has many functions, mainly in the following aspects:

1. Increase power by accelerating or decelerating;

2. Through its self-adjustment, the air intake function is corrected;

4. The function of controlling the operation of the engine assembly (the idle switch inside the engine is working);

5. Control the flap, control the size of the air intake through the work of the sensor, and use it for the lifting of power;

Dirty throttles are mostly caused by poor air quality and oil quality. The carbon deposits generated during gasoline combustion, due to the effect of negative pressure, will infect the throttle and make it not close well, thereby increasing the air intake and producing errors in signal transmission, resulting in high fuel consumption and engine idle shaking.

Therefore, during maintenance, it is necessary to check the opening of the throttle frequently, and if it exceeds the normal range, it should be cleaned.

It is the driver who controls the air intake in a timely manner according to the road conditions, which actually reflects the load of the engine, and it is controlled by the driver's accelerator pedal. There are also those that are directly controlled by the computer.

According to the size of the throttle, the load of the engine is determined, and the pulse width of the injection and the ignition time are controlled.

The throttle is driven by an electric motor on the throttle body, which improves the dynamics, safety and comfort of the vehicle and reduces emission pollution.

It can control the amount of air intake, oil and air are mixed in proportion, more air intake, the car runs strongly, and it also consumes fuel.

The function of the throttle valve of the automobile: it controls the intake air flow of the engine and controls the air entering the engine, which is a controllable valve that determines the operating conditions of the engine.

1.increase power by accelerating or decelerating;

2.Through its self-adjustment, the air intake function is corrected.

How to clean and prevent It should be removed and washed! Some cleaning mistakes of correcting the throttle!

The main cause of throttle fouling comes from oil vapor, followed by particulates and moisture in the air, which means that the throttle fouling speed will be much slower when using a qualified air filter and removing the crankcase ventilation pipe. The crankcase has a built-in crankshaft, and the bottom is connected to the oil bottom, and the working temperature of this part is about 100° 180°. The longer the oil is used, the higher the temperature, the stronger the volatilization, and the cylinder compressed air will be squeezed into the crankcase through the gap in the piston ring, so there must be a channel to release the gas, otherwise the oil bottom will form positive pressure (please refer to the related article "Night Stalker" for details).

The reason why the crankcase ventilation pipe is connected to the throttle valve is, on the one hand, an environmental requirement, and on the other hand, the air is extracted from the crankcase by the negative pressure of the intake air. When the oily vapor reaches the intake pipe, it becomes cold, and the oil in it will condense on the intake tract and throttle, and then the carbon deposits in the steam will also be deposited in these parts, because the air flow in the gap where the throttle is opened is the largest, the space is small, and the gas temperature is also the bottom, so this part is the most likely to condense.

Therefore, how long the throttle will be dirty depends on the quality of the air filter, the brand and quality of the engine oil used, the condition of the driving section, the air temperature condition, the engine operating temperature, driving habits and other aspects. Even in terms of individuals, it is not possible to determine the time to clean the throttle with a fixed number of kilometers, the first time the new car cleans the throttle interval is the longest, and then due to the continuous condensation of oil and gas in the crankcase ventilation pipe and the intake tract, the cleaning frequency will increase, and different weather will also affect the speed of throttle dirt.

Impactful. The main function of the spark plug is to point into the mixture in the cylinder, if the spark plug is damaged and does not work, the mixture in the cylinder will not be able to burn, then the cylinder will not work, and the engine will have a jitter fault phenomenon. The vehicle will have a lack of power and increase fuel consumption.

In severe cases, the engine will stall, and the vehicle will break down and cannot drive normally.

Therefore, the spark plugs need to be checked and replaced regularly. Generally, the pole gap of the spark plug is checked, and if the pole gap is less than 1mm, the spark plug needs to be replaced. Because the pole clearance of the spark plug is too large, the ignition amount will be insufficient, the vehicle will also have jitter and insufficient power, and the carbon deposit in the engine cylinder will also increase.

As long as it can be ignited normally, it will basically have no effect, let alone fuel saving. If you change the spark plug of the first class can save fuel, why don't car companies change to the best spark plug? Why some people say that it is good when they change it is because the spark plug before the replacement has been reduced in performance, such as gap changes, carbon deposits, gum adhesion and other effects, while the new one is in the best working condition, and the ignition operation will naturally be smooth.

Switching to platinum and iridium only has a longer lifespan and a more reliable tip discharge than the traditional one, rather than the ordinary spark plug that consumes oil. The selection of spark plugs should be selected according to the manufacturer's regulations and driving habits, focusing on the selection of calorific value, and not believing in exaggerated publicity.

The throttle is the throat of the automobile engine, controlling the air intake of the automobile engine, and the driving computer then judges the amount of fuel injection according to the value of the air flow sensor, so the accuracy of the air intake of the throttle valve is related to the amount of fuel injection. It is the premise of stable operation of automobile engine. So the accelerator pedal we step on is not actually to control the throttle, but to control the throttle to open at a finger level.

The air in the engine needs to pass through our throttle, and our throttle is very easy to accumulate dust, when there is too much dust, it will cause our throttle to be at the same opening, the incoming air is blocked by dust, so it will cause us to actually enter the engine under the same opening, the actual air into the engine will be less. So in this case, we need to clean our throttle valve to ensure that our throttle can accurately enter the amount of air in the engine.

Throttle. The throttle valve is a controllable valve used to control the air to enter the engine, and after entering the intake pipe, it is mixed with gasoline (different cars, different design mixing parts) to become a combustible mixed 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 truck, the 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 Cheyan Juezi is flexible or not is very related to the cleaning of the throttle. Whether the throttle should be removed and cleaned is the focus of much discussion among car owners.

What kind of fault can the throttle have?

Fault summary: The composition of the electric throttle valve can be roughly divided into the following parts: throttle valve, electromagnetic actuator, potentiometer, controller (some do not, directly by the ECU tube, bypass valve.)

There are two types of fault characteristics: hard faults and soft faults. Hard faults refer to mechanical damage, soft faults refer to dirty, disordered, etc.

Hard fault: The resistance part of the potentiometer is made by spraying a layer of carbon film on the polyester substrate, which is actually a very low-level preparation process and does not have high wear resistance. To put it bluntly, it's not as good as the potentiometer we usually add a little bit of!

The sliding contacts are made up of a row of stainless steel counter-claws, attention! It's a back-claw! This is simply to add insult to injury!

In addition, there is no protective agent on the carbon film at all, and the carbon powder that falls off leads to poor contact, and it is inevitable to turn on the light! Once repaired a carbon film that was scratched and leaked, it was only 70,000 kilometers, and the master's feet were also owed!

Soft faults: People are often troubled by cleaning the throttle because most of the time the throttle is opened too low. Air flows through the throttle gap at a very high speed (tens of hundreds of meters per second), and the gradual accumulation of dust has an effect on the air flow that exceeds the throttle adjustment capacity.

The role of the throttle valve of the car: 1. Improve the power by accelerating or decelerating; 2. Through its self-adjustment, the air intake function is corrected; 3. The function of controlling the operation of the engine assembly; 4. Control the flap, control the size of the air intake through the work of the sensor, and use it for the lifting of power.

The function of the throttle valve of the automobile is to control the intake flow of the engine, control the air to enter the engine, a controllable valve that determines the operation of the engine, such as the working conditions, and the air enters the intake pipe and mixes with gasoline to become a combustible mixed gas and participate in the combustion work.

The throttle valve of the car is the throat of the car engine, and the flexibility of the car acceleration is closely related to the cleaning of the throttle.

1. Remove some air pipes around the joint door first, and remember the location of these pipes, and then remove the joint door.

2. The side of the joint door against the combustion chamber will be dirty, which is the main messy part of our cleaning. Use a special cleaning solution to dissolve the carbon deposits, and it is best to wear a mask and gloves when cleaning.

3. Wait for about 10 minutes before using a brush to remove the carbon deposit. Finish with a towel to wipe clean.

4. Install the joint door back on the engine according to the original position, and also install the air pipes just now, and finally initialize the air joint door.
