What is the pipe between the throttle valve and the cylinder head of the car

Both tubing are connected to the exit joints behind the oil baffle in the valve chamber. A fitting passes through the trachea directly to the intake hose. The pressure effect of the crankcase is reduced, and the exhaust gases of the exhaust oil and fuel mixture are sucked into the cylinder and burned with the aerosolized gasoline.

The faster the speed, the more exhaust gases are discharged from the crankcase. The more exhaust gases enter the throttle valve as well. The pressure has increased.

The role of the valve.

It is responsible for inputting air into the engine and exhausting the exhaust gases after combustion. In terms of engine structure, it is divided into intake valve and exhaust valve. The function of the intake valve is to draw air into the engine and mix it with fuel for combustion; The function of the exhaust valve is to exhaust the exhaust gases after combustion and dissipate heat.

Hello, happy to answer your questions.

Questions. Hello, hello, these two air pipes are used to ventilate the crankcase, one leads to the air cleaner and is the intake and the other leads to the intake manifold, which is the exhaust gas.

Questions. The one leading to the front of the throttle should be inhaled or exhausted.

It's aspirated, and it goes into the engine from this tube.

Questions. Why some cars are going out to buy noodles.

Vent. That is because the lower exhaust is too big to pump, or the supercharged engine, after the big throttle intake has no vacuum, it is vented from that tube.

Questions. Isn't it all bad?

No, depending on the situation, it is not right to vent at idle speed, but it is right to vent at high load.

Questions. Increasing the throttle should be out of gas, right?

There should be only one trachea on the valve chamber cover, which is the exhaust tube. (When the engine is working, it will produce exhaust gases, and direct emissions will pollute the air, so it will be connected to the intake pipe for combustion) I don't know what car you are talking about?

There is a small pipe connected to the throttle where the intake pipe of the car is close to the throttle, this pipe is called the crankcase ventilation pipe, which is connected to a crankcase ventilation valve in the engine cylinder head.

This valve, called the oil-water separator, filters the gas mixture inside the crankcase to allow the oil to flow back into the engine, and pours the gas through the hose into the throttle valve for secondary combustion, improving fuel economy and reducing pollutant emissions.

Function: 1. The water pipe on the side is to return the exhaust gas to meet a certain emission standard.

2. The water pipe is used to heat the throttle body. Because the climate in the north is cold. The velocity of air out of the throttle valve is high, 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 throttle body is a valve that controls how much air is sucked into the engine. It is a circular steel sheet with a shaft in the middle, which is connected to the throttle cable and controlled by the throttle cable.

Extended information: Electronic throttle valve is a throttle component of the engine intake system of automobiles. It comprises a throttle body, a throttle valve plate, a throttle shaft, a DC motor, a gear reduction mechanism, and its signal output is to the throttle position sensor of the single-chip microcomputer, and also has a torsion spring, one end of which is fixed on the throttle body, and the other end is fixed on the gear of the throttle shaft;

Also has an idle speed adjustment device: the external adjusting screw is screwed on the throttle body, the inner adjusting screw is screwed on the inner cavity of the outer adjusting screw, the push rod is placed in the inner cavity of the outer adjusting screw, there is a shoulder on it, the outer end of the push rod before the shoulder stretches out from the opening of the outer adjusting screw, and the spring top rests between the shoulder of the push rod and the inner adjusting screw;

The outer end of the ejector rod rests against the gear of the throttle shaft, which keeps the throttle disc in a slightly intermittent position when driven without a motor. The high and low idle position of the present invention is adjustable, and the engine air intake is accurately controlled under the idle working condition, and the manufacturing accuracy is reduced simultaneously.

The water pipe connected to the throttle body of the car plays the role of heating the throttle.

In winter, the air of the engine is very cold, which is not conducive to the ratio of mixture, so two small tubes are connected to the cooling system of the engine to incorporate the throttle into the antifreeze circulation, and the throttle is heated through the cooling water of the engine.

In the cold car state, this device does not work, but the engine has a starting enrichment system when the car is cold, so the impact is not large, but the mixing ratio returns to the normal working state after the hot car, and if the inhaled air is too cold at this time, it will affect the operation of the engine, so this device is added.

Throttle maintenance and cleaning steps:

1. Turn on the air intake filter.

2. Remove the intake hose.

3. Open the throttle flap.

4. Use cleaning agent to spray and wash.

5. The operation is completed by installing the return filter system.

In places where the temperature is low, the throttle body freezes, which is avoided by heating through the water pipe. Today's car idling is computer-controlled, and many years ago, it was true that the idle valve could be controlled by the heat of the water pipe, and that was history.

To improve the idle speed of the cold car, many cars will have a higher speed, and the water temperature will drop to normal, and the air intake of the six solar terms will be controlled by the water temperature. I've been a car repairer for twenty years.

The two water pipes are for cooling, and the small pipes above the intake pipes are for exhaust gas circulation.

The throttle valve controls the air to enter the engine, and the gas will mix with gasoline to form a combustible mixture after entering the intake pipe, thereby combusting to form work. It is connected to the air filter and the engine block, which is known as the throat of the automobile engine.

The throttle is one of the most important components of today's EFI engine system, its upper part is the air filter air grid, and the lower part is the engine block, which is the throat of the automobile engine.

Whether the car accelerates flexibly or not has a lot to do with the dirt of the throttle, which can reduce fuel consumption and make the engine flexible and powerful. Whether the throttle should be removed and cleaned is also the focus of much discussion among car owners.

Hello, connect the waste secondary combustion pipe and the vacuum suction pipe of the brake pump respectively.

It's the water pipe, which is for heat dissipation.

This pipe is called a wastehead.

The function of the exhaust pipe is to extract the exhaust gases of the engine under certain conditions.

Part of the exhaust gas from the engine is returned to the intake manifold and re-enters the cylinder together with the fresh mixture to participate in the combustion work.

Because the exhaust gas cannot be burned, the combustion rate and combustion temperature in the cylinder are reduced, so as to achieve the purpose of improving the emission and can also reduce the content of pollutants.

Not connecting the car exhaust pipe has no effect on the engine, but it has an impact on the environment.

Some unburned gases will be directly discharged into the atmosphere, the car exhaust pipe will not be connected, and the engine may be noisy.

It is a valve valve that can control the engine, and the throttle valve is connected to the air filter on the top and the engine is connected to the engine below, which is in the middle of these two things.

There are two main parts to the structure. The first is the air filter, which is responsible for filtering out impurities in the air. The second is the air intake pipe, which introduces air into the air pipe.

Throttle valves, potentiometers, bypass valves, solenoid actuators, controllers, are organized by these few parts.
